DT125R FORUM

When I see someone with the same colour and model DTR as me...

Welcome to the forum mate, I've only had my DT a few months but been on here since before I bought it, a great bunch of people on here and you'll find that no topic ever goes unanswered, which I've found is quite rare on other forums
And speaking of having bikes in the house.. When I got my first ped at 16 I insisted it sat in my bedroom until I did my cbt, and sat in my bedroom it did.
And the ped I got when I was 12 did also. What tolerant parents I have

Set about fitting the 3MB head today.
My torque wrench is too big so went to halfords for one, now if anyone here lies in Derby they'll have heard about the round about in Kingsway that has recently been made larger and now has a load of traffic lights on it. Well long story short, it's fucked everything up and they're shit, the retail park next to said roundabout was completely grid locked. It took about an hour to et out of the retail park once I'd been to halfords. Fabulous.
Anyway, £80 later-

Then the ball ache commenced:

Old 3BN head off:

Nice clean 3MB head on and all put back together, with genuine yam head gasket.

Started about 4th kick, took for a ride and can tell it's got more compression, it vibrates more too and seems abit nippier, will be better when I get my new zaust.
Unfortunately the sender wotsit in the head for the temp gauge looks completely different to the one in my 3BN head, hoped it would work but it doesn't.. Stayed at cold the whole time I was out. So I'll need a new one of them:(

Head cleaned up well, I'll be using the thermostat and other bits off my current head as I know they work

A hoon around the back lanes was also had afterwards:D

Mild mods while retaining the original format is the route I've gone down, while keeping all the original bits that I've taken off to be put straight back on if the time does come to sell it. The temptation to go abit crazy will always be there but having known the guy I bought it off all my life nearly, and taking it to him to mot it every year, I'd get an arseholing for it

More on topic though it sounds like mr horny head hasn't a clue what he's doing, hasn't mixed oil with the petrol and shagged his top end, completely his fault and not your responsibility. This will blow over I'd have thought, he doesn't really have a leg to stand on, shame he pressed buy it now though as eBay will take they're chunk. Yeah there'd have been more things you could've done like a receipt and some disclaimers to cover yourself but it's not the first thing you think of doing when selling something

Finally got it taxed and went out on it today, lots of smiles all round, handles great even on those knoblies and pretty damn quick, got 75 out of it down a straight riding against the wind, but it's the getting there that's the most fun bit, can't wait to get a decent pipe on it!! :DD

Honestly if I had the licence, I'd get an MZ Baghira. Husqvarna frame, Yamaha 660cc single with an Mz badge. They're the dogs dandies and won't break the bank either

Here's something you don't see everyday, or even a year. A Suzuki RG500 that's never been started let alone ridden. Lived it's whole life sat in someone's office under a sheet.

Part of me wants the person who buys it to fill it up with all its fluids and ride it like it was made to be ridden. Although it's quite clear this bike will most likely never even get fired up. A shame, but also quite fascinating to know of such a legendary and quite old bike that is essentially brand new.

Not much of an update but gave it abit of tlc the other day.
I must say, if you've had trouble finding products that do what you want to add some good shine, Auto Glym works wonders.
I used Auto Glym rapid detailer on the plastics and tank (their super resin polish didn't touch it, but this spray makes it like new) and their trim gel on things such as air box, clocks, fork gaiters and brake disc cover brings all up really well.

The only other mods I really have on my list for this bike are a zeeltronic ignition and possibly a WR200 swing arm if I can find one that isn't in fkin Australia or somewhere stupid.

@Calum said in '99 DT125R "OEM+":

@Burridge Nah must admit thats not on really!

Fingers crossed though that the performance is at least decent!
Shut up it is!!! Hahaha

Sorted the midguard problem out, a nut between the top of it and the bottom of the yokes gave enough clearance and it looks no different so I'll be leaving it like that. Everything tightened up I took it out and the faff has been worth it. It's transformed it completely, power kicks in at 6000 from the pv opening then at 8000 the pipe kicks in with a nice rasp, and goes on to go off the clock at 80mph

Next problem: melted my boot on it.

Well guys I've managed to get it on, all be it big faff. Haven't bothered with the bracket as Calum's said, cut an inch and a half off the end and got the dep on, the 2 pipes were so far out they were almost side by side. Put a spacer on the front bracket of the dep to pull it out more to like up abit better with the main pipe, used the original grommet with a piece of handle bar grip packing out the main pipe cus it was far too big.
Next problem!!

The pissing front midguard hits the pipe when turning the bars left! For now I'm gonna pack out the 2 bolts holding it on
closest to the engine to angle it away from the pipe, and maybe get a different midguard later on that I can butcher abit to fit round the pipe.

@mightyman I know how you feel, this thing wasn't cheap and as good as the workmanship is I've been pretty pissed at how badly it fits, with the equipment the guy has to make these things and how much he's making off them I'd have thought he'd have some decent jigs to make sure they fit better than they do. It said in the title that this was for a dt125 r

Hopefully I don't get the ban hammer for posting pornographic material but I'll take the risk.
Postie brought this today

@dtluke said in 3MB head.... Should I buy it?:

@AndyYam is the 4DL as good as the 3MB? I've just put on my third head gasket now (Athena gasket) and still have a leak so I'm guessing my 3bn is warped anyway

Use a genuine Yamaha gasket when you put your new head on, a lot more money but it'll be worth it

On a serious note though (last post also serious mind) I'd send that thing back. It's clearly been sat in his toilet for the last year or so. If it's going anywhere near your engine you want bits that aren't half dead from the get go

Cheers guys, I'll keep a look out on eBay, I don't mind something that needs a good clean or a skim, I've skimmed a head before on a piece of glass with fine grinding paste haha and it came out well, just as Calum said it needs to not have any pitting or damage on the combustion chamber, and it's hard to make out in pictures sometimes

So since before even getting my DTR a couple weeks ago I've been reading up as much as I can about them, restrictions etc. And seen that the 3BN head has a restrictive squish band, does anyone have any idea where I can get a 3MB head? eBay is abit hit and miss, all I've found on there so far are heads that look like they've been frisbee'd off a cliff

Thankyou in advance

@Biker_123 Mate you got off lucky, it lasted from 8-5 this time!!! Got home and fell asleep at 8pm, dreaming about pissing shoulder checks.

Hello there,
So as I was taking my YBR125 for its last MOT the other week to then sell it and put the money into savings, I saw a black DT125R at the place I've always had my bikes MOT'd, had a sit on it and knew I needed it. So much for "savings".
Got the YBR sold within a few days and went back just the other day to have a closer look at it, it's a V-reg, so '99? and having done research a late 1999 as it doesn't have the steering lock on the ignition barrel?
Anyway, it's done 2500 miles, and from the condition of the bike and the keys it's genuine. Started 3rd kick after not being ran for a good while and I had a pootle on it round the car park.

I get paid in a few days and plan on going back down and buying it.

Since seeing it I've been researching DT's as I previously knew zilch about them.
At the moment I'm trying to determine what exact model it is if it's a late '99, and what that translates to in terms of restrictions etc, and more information about this Zeeltronic ignition system, how I'd go about setting it up and most importantly if it's compatible with the bike. (fitting it shouldn't be a problem, especially not after doing a full 12v ignition system conversion on an old MZ)

That's all for now, any info greatly appreciated and I hope to be back here soon as the owner of said DT

I may be very biased but my dream DT is my own would still love to do a supermoto conversion on it though. And the twin can setup on that does look cool

@MIGHTYMAN
They are pretty loud, depends what engine size mainly though, a little .15 isn't all that loud but .21 and up just scream, sound like a chainsaw when ticking over
