Forget the dep the fmf has given me more bottom end and mid range without effecting the top end feels slightly heavier than the dep but I don't think this pipe will rust out like the dep

Italian made 1988 model

Appreciate the response I've only chose the dt125r as silly as it sounds I almost lost my life in a crash on 1at the age of 17 came close to amputation to my right leg just below the knee i also shattered my shoulder socket broke collar bone and a internal bleed, I had always planned to do a nut and bolt rebuild on 1 after that but not found the time til now altho whilst looking I found they were all going up in price and to be fair even a bad 1 was around the £1000 mark so I spent the extra on what I consider a half decent 1 I plan to use when the summer comes as little as we may get and then strip it to rebuild through the winter, I had no plans to mod it at this point however on riding it you can feel how restricted it really is but that really is where the interest of the dt125r comes into it. Off road I ride a 06 crf450 that I've converted to run a 2001 cr500 engine I built the bike from scratch last year so basically from 1 extreme to the next and 2 totally different bikes

Frame been acid dipped to kill any rust and then acid etc primed

Quick test fit up before it gets rebuilt

Mick Abbey tuned wr200 cylinder and head ready for the transplant

Honda bit slow on the uptake, 1 i made earlier

thought I would share my other pride and joy my cr500r 06 crf450 with a 2001 cr500 2 stroke motor I build from scratch

@Zrako
There you go mate its in a cr450f frame

vapour blasting doesn't damage the seals or anything

Seeing as it's a nice day I thought I'd put it back together at least until the 200 engine is back anyway

New bike anyone 1 careful owner low mileage cheap runner no knocks or bangs recent rebuild no time wasters

@Darty yes mate in Bude it's tatty really tatty it's not had mot for a few yrs now but it's fast I'll give it that, it will power wheelie 1st 2nd and 3rd on the power valve, it's got a puncture but gonna put a tube in it and take it for a blast see if it will wheelie in forth . The bloke has a j reg 1 there he's gonna drag out its tidier than this 1 but apparently it struggles to select gear when it's warm I'm probably gonna buy that as a spare

@scrimsmustang
Gonna copy this 1 on my 89 try and make it look pretty and then list it again

See this thing, shame it burnt itself out

It is registered but currently no mot I did have a daylight mot but you find its constantly on the back wheel I think it's a bit too easy to lose your licence too but it's definitely fun to ride on or off road, I have both sets of rims and a adapter plate to space the front brake as the sm front brake discs are bigger and change and the rear calliper mount is different but I've always kept all parts needed guess it's a matter of weighing up the pros and cons

It's not mine I saw it on Facebook, mine is under lock and key 3 locks and a pitbull before anyone gets to mine thanks tho

@CYBER-NINJA lmao both sounds like bit of a chore

Few more bits all stripped back to bare metal including a fuel tank already for primer

All stripped and ready to post to mick abbey tuning

@Kieron12345 I've seen it where it's fried the piston All down the front with the power valve shut too where it can't get the exhaust gasses out quick enough apparently, It's 2 stroke it's gonna go through pistons no matter how you ride it so you may aswell get the most out of it

My rgv250 was a animal i find hard to believe a rs125 would come anywhere close to it

Hello again I'm Andrew from Cornwall back after a few weeks out bit side tracked with my new toy a evo 6 running 376bhp, my dt125r is a 1994 model was totally standard and only every covered approx 4320 miles with all old mots to verify, by far from my first dt125r I've had a fair few now. I've fitted a front and rear del and I've had it rejetted it's now running a 250 main however I find the cdi is pretty restricted so now I've ordered a new zeeltronic setup from borut I'm just wondering how hard it is to fit and does it come with a basic map or do I start from scratch? Any help would be much appreciated. Many thanks Andrew

@scrimsmustang looks like you've have some good ones, wish I'd known you before I got any of mine as I was only meant to buy 1 decent example

Some tool

This look about right?

Ordered some nice new bits today a fmf fatty front pipe and power core rear silencer along with the exhaust flange adapter witch will allow me to run the fmf, spoken to mick abbey to ported the cylinder and modify the squishband, it looks like it's been rebuilt not so long ago the gaskets are pretty fresh but gonna open it up for piece of mind and rebuild it anyway makes sense too. Bad side I'm having problems finding panels I want a full new set really but according to fowlers of Bristol they are discontinued

It tells you someone has done a bad paint job in the past in the least

That join doesnt look too good surely my tail pipe slots over the front pipe leaving a nice tidy surface for my rubber to sleeve over

@declan said in Anyone mounted fmf on Dtx?:

Wr200fmf is a direct bolt up all I did was mount it on the rear on the grab handle rather that the original exhaust mount

I've ordered a set of these the pivot back or forward too

I had this problem the tabs were worn on the wheel, i started cheapest option first being the cable and lastly changed the wheel which sorted it

That's the same as mine, that's the bike that's been reframed on ebay aint it?

Looks like you have this 1

@dan28 the cap is included in the pics I've posted mate the cap has the pin in the base which then locks into the sleeve the sleeve slips over the power valve and mine doesn't spin inside it then the cap locks in place through the 2 holes where it bolts to the cylinder holding everything in place

@dan28 I have the early version the same as you if you pull the power valve cover off the left side of the cylinder there is a sleeve that slots over the top of the powervalve itself when you pull the sleave out there is a pin in it basically turn the valve 180 and put the sleeve back but insure you turn the sleeve the pin will need to locate in the top now rather than the bottom as long as you still have the pin in the collar you can't get it wrong however I have seen this pin removed where people without the know how have tried to open the power Valve and snapped it off

@Louis-James thanks mate appreciate it I'll get on it tomorrow first thing, there is nothing wrong with the crank in it but knowing my luck they will have discontinued it by the time I do need it lol always the way ain't it

@Louis-James think thats how I'll go about it, when I spoke to fowlers they were suggesting I had to buy the crank in 2 halves is this right? Your don't have a part number do you bud? Seem to be getting a lot of ideas from your build the bigger carb reeds for example it's nice to know it's already been done

ideal know for next time, cheers bud

@Calum I didn't mate no lol only just getting used to it, will delete my pics and leave yours as its all in 1 then

Mine were good but I did upgrade to the carbon ones from eBay chaos stage 1 I believe, instantly as soon as I started it you could feel the throttle more responsive admittedly it didn't make loads of difference but the bike did seem to rev more freely I think it's all the little things that add together to make a complete package reeds should be a must, I've already ordered another set for my next project.

Thats prob half your issue you wanna try get that sorted

I also have hy-tech carbon reeds and I would say my bike is too thirsty for a 125 it goes through a full tank in no time at all probably just as thirsty as my mitsubishi evo

Mine didn't like too much air I've had to seal Some of the hole back up and I'm running a full dep exhaust carbon reeds and a 250 main jet

What's people's views on fitting my mikuni tm30ss carb from my wr200 to my dt125r was wondering if there would be anything to gain from it as I've picked up a 34mm upgrade for my wr200 so have the tm30ss doing nothing and looks almost new be a shame to see it go to waste

I have 2 in my kitchen and a cr500 in the bedroom

Worse case its only £41+vat complete new

My spring doesnt come up through the holes like yours does, the legs sit underneath the same as it does in the Haynes manual image

@Uber_Beluga you will definitely need a torque wrench mate and a flywheel puller

@Darty am I right in saying the port timing is all out on the 170 kit too? Sure I read somewhere something about it as I did look into it myself

Each to their own their is loads of different factors to take into account like condition of the engine itself how often it's serviced has the kit been run in properly and how the bike is ridden a extra 45cc is alot of strain for a crank

For the sake of £20 on gaskets and 30mins work I would pull the top end off could be little or nothing but atleast you know. I'd cringe riding around sounding like that I'd be constantly waiting for it to go bang

@irongamer727 that is something abit more than the powervalve vibrating I'm sure I'd look into that abit more if I were you, could end up costing you a complete rebuild if it goes

7 bloods clots below the knee and far too many idiots on the road for my liking, don't think there is much to finish it, paint the tank as I've have it blasted due to 1 small ding in it and change some light connectors

Hello lads lost interest altogether and thinking it must be worth more in bits, it's running a wr200 3xp engine with a ported and modified squash band done by mick Abbey tuning a full fmf exhaust for the wr200 direct bolt up, has wr200 upside down forks along with the wr200 front brake setup it also has the wr200 alloy rear swingarm with adjustable damper

It tells you someone has done a bad paint job in the past in the least

@scrimsmustang my fmf came with a adapter plate that bolts straight to the head and then the front pipe slots over the top and then 2 springs to hols it together the same as you do on the crossers

@declan said in Anyone mounted fmf on Dtx?:

Wr200fmf is a direct bolt up all I did was mount it on the rear on the grab handle rather that the original exhaust mount

It's alive I decided to run it on the 3xp loom and cdi unit so after changing a couple of connectors for both the front and rear lights I have a full set of working electrics again, still can decide what colour to paint the engine cases do I go silver to match the alloy rear arm and usd forks or do I go for the darker grey what are people's thoughts

Even so mate I'd love to do it

Stunning cars mate some of us would kill for cars like that

Living the dream

@zrako ideal thank you, I've been searching for hrs on the net for some sort of picture to see if it does your a star you've put a end to my headache

Another 1 for you guys an I right in thinking the loom on a dt comes through in between the front mudguard and the bottom yolk on the forks?

http://imgur.com/henNb7f
Starting to look like a bike again, 1st test fit

http://imgur.com/jvexlUq

@oldman thanks will look into

@declan sorry declan it's true there are a few different builds on this forum ask each 1 of them if they thought about cost first

@oldman do you have a number for the place you got your original graphics? I have copies but would rather original if I can

@calum thanks mate. Keep up the good work without you we wouldn't even have a forum. I personally couldn't find enough hours in the day to keep on top of it. Well done mate

@cyber-ninja even 1 picture at a time seemed to be a problem I don't know maybe my phone I've had to go back to my old 1 I managed to smash my screen while fitting the engine in this one . Calum don't jinx it everyone else seems to be in it to make a quick quid I can imagine imgur isn't too far behind

@cyber-ninja it wouldn't let me do it that way for some reason mate kept telling me too big entity but I got there in the end that's the main thing lol. Thanks guys

@irongamer727 I bought a complete bike bud it was a dog of a bike to look at but it rode well with plenty power

@irongamer727 I have just fitted a dt200wr 3xp engine in mine it's a direct bolt up apart from needing 3.5mm spacing washer either side of the front mount As the front of the engine where it sits into the frame is 7 mm narrower than the original dt125r engine

The dt200wr has a bigger disc and twin piston calliper

For the sake of £20 on gaskets and 30mins work I would pull the top end off could be little or nothing but atleast you know. I'd cringe riding around sounding like that I'd be constantly waiting for it to go bang

@irongamer727 that is something abit more than the powervalve vibrating I'm sure I'd look into that abit more if I were you, could end up costing you a complete rebuild if it goes

@nottsbiker with the wr alot of the parts are discontinued so if you come across bit of a dog your better off breaking it, I tried to source replacement panels and graphics but it's not happening and then a decent dt125r seems to make more money than a wr200 I think half of it is if your gonna cross over and go above a 125 with a full licence why stop at a 200 I personally wouldn't therefore the 200 in form of a 125 sounds good to me

Can't imagine you getting a 3xp engine cheap, I looked before I ended up buying a complete bike even a 3et on eBay was £450 time you paid postage

I'd say piston rings at a guess maybe just a cracked ring would cause issues

That or small end rattling worse case

@scrimsmustang it's hard mate do you know when you buy some for good money I gave £2200 for it and soon as I had it I noticed lose bolt bolts missing the I have a speed wobble that was horrible the tyre had cracked up I don't know how he got it through a not then I had the issue with the oil baffle plate and the water propeller I've gotten to hate the bike if he lived closer I'd of been banging his door for my money back it's a shame as it is a good looking bike but it's destroyed my ideas of having 1 I just want rid of everything dt/we

@scrimsmustang looks like you've have some good ones, wish I'd known you before I got any of mine as I was only meant to buy 1 decent example

@scrimsmustang how much is the right price scrim? I could be tempted I need to move a couple first ideally tho as I have far too many can you send me a few pics to my msg box please

@scrimsmustang can imagine that 525 was a handful, i have a 2001 cr500 motor in a 06 crf450 chassis and you cant keep the front down

@scrimsmustang always liked the yz250 more than enough power, quick little bikes

It is a dt200wr yes running the 3xp cylinder and head and a tm30ss carb that I'm planning to drop into the dt125r

They were a tad expensive but its 1 of them things you only buy once aint it

I've ordered a set of these the pivot back or forward too

I have 2 in my kitchen and a cr500 in the bedroom

Something wrong with your bike if its not coming in until 8k lmao mine comes in at 6 and its not all that gutless before that either

@calum I'd agree with you my probs topout the same hence wanting to give it abit longer legs but then i like the bottom end power its a matter of finding something in the middle

@declan not alot of space needed bud they get there nice and fast

Thats prob half your issue you wanna try get that sorted

Ive always been told to adjust the mixture screw til it idles at the fastest point turning quater a turn at a time and then turn the idle screw down to suit

I have a rebuilt wr200 going into mine that did 104mph before it was rebuilt and mick abbey tuning cylinder and modded head, I'm having frame painted monday/tuesday i had the wr200 fork clamps bored to take the dt head stem and all the alloy rear swingarm and shock has been stripped right back and polished, not sure if I'm gonna run a wr200 loom and cdi or dt loom with zeeltronic

@terry-tz think I'll try that 1 combo closest to that i have is 15/57 but it is fast til 70 but wont go even a mph over weather down hill or up hill it doesnt matter, the engine has a tuned cylinder and modded head so even in top gear it pulls like a train but once it hits that 70 thats it

I have 1 bike running 15 front and 57 teeth rear tops out at 70mph , another running 16 front 53 rear tops out at 68 another running 17 front 52 rear not sure what its topping out as the speedo isnt working and another 50 rear and 13 up front but no speedo at all lol

What size sprockets are people using? My dt i use mostly seems to stop pulling at 70mph but gets there fast abit too fast for my liking so thinking of changing sprockets i see a few of you suggesting yours do 80mph what size sprockets you running?

I dont know about that 1 mate but see what i mean about them being more fun, my dt i use most just to thrash about has now covered 1100 miles with the pv pinned and it hasn't been a problem at all

At a guess mate that 1 sends signal from the cdi unit, have you tried riding the bike to see if it still cuts in?

The powervalve is different you would have to change the whole lot in my opinion its not worth it the servo takes the fun out of it anyway

My rgv250 was a animal i find hard to believe a rs125 would come anywhere close to it

Highly unlikely you would swap a wheel on a bike with that mileage you just wouldnt need to if the mileage was correct

@calum can you really see the wheel lungs wearing at less than 7000 miles then as i cannot

2k will get you a fairly decent bike and the best bit about it is they are only going up in value

For example then how does the the wheel wear to the point it doesnt work the wheel block for the speedo with only 6892 on the clock lol i think they are clocking them knowing that there is no history of mileage available to potential buyers there is little tell tale signs like the rubber condition on the kick start the original grips being worn all point to the bike doing alot more miles than the clocks say

I had this problem the tabs were worn on the wheel, i started cheapest option first being the cable and lastly changed the wheel which sorted it

Speedo screen was cracked and the speedo drive on the wheel didnt work i had to change the front wheel before the speedo worked luckily i had a spare. It smokes a fair bit too so I'm guessing they are changing the mileage when they come in as there is no way mine has only done 7000 would make sense as if you have taken any notice all the bikes they have listed a very low miles

I've dealt with them in fairness they are a pain in the ass took them over 2wks to deliver the bike and then i only had the bike and a receipt i then had to hound them for the dating certificate which you need before you can mot the bike even tho it stated in the listing all paperwork to register in hand however this was not the case and apparently the blole was on holiday so i had to wait for him to return. My advice would be to buy 1 already registered

That 230 lanza looks very similar to the wr200 apart from the front forks but even the frame looks the same

I have a wr200 exhaust on 1 of my dts mate and i had a gap similar what i did was use the bolt hole that the grab handle goes on instead and the put a washer over the bolt that would normally go through the bottom tailpipe bracket and tighten that the bottom mount should be just infront of the original bolt hole

That join doesnt look too good surely my tail pipe slots over the front pipe leaving a nice tidy surface for my rubber to sleeve over

Worse case its only £41+vat complete new

I dont think you need a new spring you need to push the feet of the spring back through, the spring is pretty slack on all ive seen but not had any gear selection problems

My spring doesnt come up through the holes like yours does, the legs sit underneath the same as it does in the Haynes manual image

New bike anyone 1 careful owner low mileage cheap runner no knocks or bangs recent rebuild no time wasters

Totally different bike to ride without, the powervalve hits so much harder when it kicks in, the servo just smoothes out the power delivery i think but definitely prefer it without but each to their own i guess

Ok so i have a S reg here that ive bought to rebuild the pv as you can see has been pinned it pulls nice and strong every gear to the point it comes off the clock yet i dont have the same issues as above and the only difference is i have a standard front pipe

Cant see pinning the pv would be a issue mine 95 model didnt come with a servo and the pv is pinned wide open on that and its covered 600 miles in the last 3wks with not a single problem

Its only the waterpump 1 whatever theey used to glue it has melted the propeller so it must of been running at nearly a 45 degree angle nowonder i had vibrations, just not sure if i am able to get the oil baffle plate as its bent it

I dont understand why someone would go through whole process of rebuilding a engine and the to glue a plastic cog which ive just ordered new is only £13 gets me

@CYBER-NINJA mainly on road i ended up ordering mitchelin comp 3 for the rear and comp 6 for the front they seemed to have good reviews

What are people running on my new dt i have a kings rear tyre and a golden tyre on the front and it feels like its on ice

@Uber_Beluga you will definitely need a torque wrench mate and a flywheel puller

I also have hy-tech carbon reeds and I would say my bike is too thirsty for a 125 it goes through a full tank in no time at all probably just as thirsty as my mitsubishi evo

@Alastair thanks I think the 1 I have my eyes on has only done 6000 miles If it's that easy I might take the tipper over

@Alastair hello mate did you bring the dt over from France yourself? How easy was the whole process? I only ask as I have my eyes on another dt but it's in France they seem to be cleaner bikes over there

@Mightyman
That's result of a piston hitting a power valve the cylinder melting shows the carbon buildup etc I know the difference

@Mightyman I've seen it first hand mate it melts the front of the piston dead in line with the exhaust port, I personally pinned the power valve with the idea it's 2 stroke it's gonna want rebuilding from time to time

@Kieron12345 I've seen it where it's fried the piston All down the front with the power valve shut too where it can't get the exhaust gasses out quick enough apparently, It's 2 stroke it's gonna go through pistons no matter how you ride it so you may aswell get the most out of it

@Calum I know wouldn't be buying a dt125r if I had a full licence lol defeats the whole idea surely

@Calum learn something new every day

I believe they didn't fit the servo before 97 unless it's a import I have a 94 and mine doesn't have a servo, your best bet is to open the power valve and pin it

The nipple is there its just the pipe has been cut if you look at it just take that bit of pipe off and replace it that 1 goes to the inlet

There is normally 2 one to the inlet and the other you can see in the pic goes to the bottle, looks like you will need a new pump, that or pre mix fuel

At least all is not lost he has a frame and a Id it could be worse they could of gotten rid of the frame number Not that I would wish that on anybody I'd be fuming, good luck with piecing if back together

@Zrako
There you go mate its in a cr450f frame

@Zrako I think so yes, it was also on my cr500 originally someone had tamed it down it now has a 39mm

Ideal appreciate the response, opens my options up about what I can put on there I have a 35mm pwk air striker carb I'm wondering if that maybe too much

@Mightyman thanks mate I only run mine during the warmer weather so guessing I will get away with it if that's the case, just don't want to cook the motor

@Darty did I see you needed a new dep?

@Darty I thought it was yours he did I knew I had seen the name someone on the forum but couldn't find it, thanks mate looks alot tidier than the job mick abbey did with my dt

Just wondering if anyone has used kpmotosolutions before? I'm looking to have my wr200 engine tuned

I did both on a dtr thinking I was clever that thing would wheelie in forth

Fowlers have a website I use them for all my genuine parts I would start with your cheapest option the temp sender that bolts straight in the top on the cylinder head

Think those little bikes are underestimated I bought a kx 85 for my 8yr old son and that thing will power wheelie on the power band 1st 2nd and third with me on it and I'm a tad over 16 stone from pull away it will kill my dt

You could always just stick a big washer behind the bolt that runs through the middle you can lock it off that way which is what I have ended up doing today as since having port work and the power valve modded it kept moving a little over fully open

No its not I've not seen that one

That's the same as mine, that's the bike that's been reframed on ebay aint it?

Looking good mate

You should have this 1

Looks like you have this 1

Funny you say that calum mine is drinking fuel lately I always use super unleaded from tesco but i seem to always be filling up

See I sent my dt parts like that, I paid £170 including my postage back but he didn't skim the head or cylinder so now wondering if that is why or just the fact they didn't need it maybe

All stripped and ready to post to mick abbey tuning

Mine were good but I did upgrade to the carbon ones from eBay chaos stage 1 I believe, instantly as soon as I started it you could feel the throttle more responsive admittedly it didn't make loads of difference but the bike did seem to rev more freely I think it's all the little things that add together to make a complete package reeds should be a must, I've already ordered another set for my next project.

Ordered some nice new bits today a fmf fatty front pipe and power core rear silencer along with the exhaust flange adapter witch will allow me to run the fmf, spoken to mick abbey to ported the cylinder and modify the squishband, it looks like it's been rebuilt not so long ago the gaskets are pretty fresh but gonna open it up for piece of mind and rebuild it anyway makes sense too. Bad side I'm having problems finding panels I want a full new set really but according to fowlers of Bristol they are discontinued

@Mightyman New to all this computer tech but will keep that in mind

all stripped ready to be blasted and powder coated

@Calum after riding it I'm toying with the idea tbh probably make a ideal project it rides pretty nice

@Darty yes mate in Bude it's tatty really tatty it's not had mot for a few yrs now but it's fast I'll give it that, it will power wheelie 1st 2nd and 3rd on the power valve, it's got a puncture but gonna put a tube in it and take it for a blast see if it will wheelie in forth . The bloke has a j reg 1 there he's gonna drag out its tidier than this 1 but apparently it struggles to select gear when it's warm I'm probably gonna buy that as a spare

@Mightyman they look alright in pics mate but if I am honest it looks like a dt on steroids it's too bulky the dtr is definitely the better looking bike I think

@dtr-mkd I'd take the cover off and check it's all moving as it should if so pin it in the open position and unplug the servo then try it again

Calum he stated his bike was the dtr and I know my f plate dt125r was a manual power valve and the only restriction on it was the power valve

Being a 88 model I'm guessing the power valve isn't on cables the best thing you can do if not is take the cover off the powervalve on the left side of the cylinder head and rotate it 180 degrees and then refit the cover

Appreciate the response I've only chose the dt125r as silly as it sounds I almost lost my life in a crash on 1at the age of 17 came close to amputation to my right leg just below the knee i also shattered my shoulder socket broke collar bone and a internal bleed, I had always planned to do a nut and bolt rebuild on 1 after that but not found the time til now altho whilst looking I found they were all going up in price and to be fair even a bad 1 was around the £1000 mark so I spent the extra on what I consider a half decent 1 I plan to use when the summer comes as little as we may get and then strip it to rebuild through the winter, I had no plans to mod it at this point however on riding it you can feel how restricted it really is but that really is where the interest of the dt125r comes into it. Off road I ride a 06 crf450 that I've converted to run a 2001 cr500 engine I built the bike from scratch last year so basically from 1 extreme to the next and 2 totally different bikes

its me again calum andrew1680 I logged out and it wouldn't let me log back in so if you wanna just delete that account I will just continue with this 1 ive had to set up a new email to link this profile too so just as well continue as I am, thanks for the help really appreciate it
