So the project isn't dead I've just been extremely busy with work.

Finally found a twin rad setup that works - https://www.ebay.co.uk/itm/252198042402

The bike is currently at the machine shop getting the engine brackets and radiator brackets made up.

And this arrived today

It's back!!! The wheel is finally back!!

So this is a 19" yz excel rim on a dt125r hub.

Fits nice even with the wheel pushed althe way towards the engine there's still clearance.

Got the new bolt for the dog bone to mount it to the frame from fowlers

Just waiting for the rear axle spindle to turn up so I can get the rear wheel fitted

I wouldn't bother with that. Seen them snapped quite easily. I would use a ground anchor and chain when at home and a chain around the wheel when out. Always try and chain it to something when your out. Remember even your own garden isn't safe.

When I lived at my parents we had a large garden with a dog that always barked at strangers yet one night I found my motorbike was missing!! Ran up the garden at 3am in my pants to find her resting at the side of the road on the kick stand. Guessing they went to get a van. I was very lucky

So this turned up today

Yeah fits but needs a few modifications. Needs custom head to frame brackets and the front engine brackets.

The decider was the fitment between the swingarm and that fits no modifications

@Zrako calum's method works great. i've got some close up pictures so you can see how it works

https://dt125r.co.uk/topic/595/project-i-can-t-leave-things-alone

i used a stock dtr lower bearing in the frame with the yz forks and the stock yz top bearing sat in the new bearing cup

How much did you pay just out of interest?

I picked this up -

Don't really know what gas gas model it is apart from being 320cc.

Bought it at 5pm for £400

Crashed it in the field at 6:30pm ripped the back off and bent the wheel.

Sold at half 7 to a guy that races them for £700.

lol not really sure what I had.

So here we go once again i'm rebuilding the bike

this is where the project starts:

i have already made a start and thanks to @Calum 's bearing cup guide i have started making the yz125 forks fit my dtr.

so lets talk forks..

i had the bearing cup made up at a local machine shop using Calum's design. i took the design down with the frame and the yokes. the measurements had to be adjusted to make the cup fit the frame as the size wasn't correct for my frame. i'm not saying his design and measurements was wrong in anyway it just wasn't quite right for my frame. unsure if it changes throughout the models slightly.

so as the yz125 stem is longer and the stock yz top bearing is large than the dt frame the bearing cup is required to make it all fit.

i used a stock yz125 top bearing and stock dt125r bottom bearing to make it all fit. no modifications are required to make the dt bearing fit the stem it's the correct size believe it or not and theres no play.

the axle spindle is larger on the yz forks so you will need to use the yz front wheel.

TBC

Before I messed with my 2000 dtr build quality was great. The 3mb I think it was? Never let me down

Haven't posted in a while but things are still slowly moving .

The wheel has been with the builder for a week now so hoping to have it back soon.

Ordered the wrong front yz calliper doh!! So sending that back and ordering another. They calliper carry is wider on a 98 then the 97. My forks are 98 .

The yz exhaust has arrived as well but I forgot to take a photo. It doesn't quite fit might need a little bit of heat and some bending to make it work but it's not to far off.

Welcome

Hi all so here we go.... my 2000 dt125r

i've had the bike since 2008 and it love it.

a picture from my last overhual in 2012

some pictures of me having fun the day she got her mot after the last over haul.

I've really loved this bike and i took good care of it. i was riding it up until feb 13 when i got my car licence and then it sat.

during this time i managed to find a yz125 engine that i thought would be great so i sold my 3mb fully running engine to a friend for £150!!!!! DOH looking at the prices of them on ebay now i feel a bit stupid.

TBC

Very nice it's hard to find one that hasn't been hacked about. Can hardly call mine a dt anymore lol

@Calum was still a size/rez issue but lets you get to 100% on mac

@zrako I'm sticking with off road but I want to use the 19" rear

Hi all,

My names Gareth and I'm 27 from the Isle of Wight, uk.

I've got a dt125r 2000 and a drz400 2006

A picture would help us see what you are seeing

I used a hel set like this with no problems - http://www.wemoto.com/bikes/yamaha/dt_125_r/88/picture/hel_front_hydraulic_hose_-_standard_set-up/

Be careful with discs I can't remember what type it was but once I went for a cheaper disc and it would rust over night where as the more expensive ones didn't rust at all. Sorry not sure what the coating was called

look good @Darty.

do you have it up and running on your bike?

Thermostat stuck closed?

Man I love that clear clutch case

I have it on the rear of mine as they are road legal.

This there’s a picture in my built thread.

Haven’t ridden on them yet but they look great

I went with 112. If it’s to long I’ll shorten

i've decided on

13 front
48 rear

@Darty do you think there will be much need for one on a yz? or the cdi will be well tuned as is?

@scrimsmustang were you using normal bulb lights? i was going led all round.

my m.o.t tester is one of the 3 blind mice

So the new stator with lighting output turned up today.

But still no sign of the bike

look good @Darty.

do you have it up and running on your bike?

as i need to build a loom i'm interested in this system.

what are they like to setup for someone who has never used them?

i'm not a complete novice as i work with winols but i'm not advanced either

You can get them both from fowlers.

Sorry should of made my question more clear. Did
These come on the bike from factory as they
Weren't on my bike?

Hi all,

does anyone has these on their dt?

Number 7 in the image

COVER
30X-2219X-00

when i took mine apart i didn't have these on the bike.

thanks

@Calum i don't have an account and i'm lazy

i think the cowling was £120 and the rest came to £275 not bad for genuine parts that aren't really around anymore

@Calum was still a size/rez issue but lets you get to 100% on mac

Right lets try again...

so these turned up yesterday

had the headlight cowling a while but i finally ordered the others.

all brand new and genuine.

i haven't ordered the front mud guard yet as i think i might use the more sporty looking yz one.

I don't think so... I've got an Apple ishit and it's stayed the same as far as I'm aware. I'll upload them to the mac and try again

Whora hijack!! Haha

@scrimsmustang just bolting a light to a yz isn't fun. It's all about building something your way that no one else has.

I'm not some one that can just buy and sell bikes I get attached to them. I've had my dt 9 years and it changes with me. No other dt would ever feel the same. Its like having a child and watching it grow.

@Calum ah ok thanks annoying. Has it changed? I used to upload from my phone before.

 

Error request entity to large

Hi all,

So.....

The project isn't dead but I still don't have it back from the machine shop. It's only been 4 months for a couple of brackets I'm going to get a bit pissed with the guy soon!!

But these came today


Hmm getting an error uploading photos...

does the stock dt wheel fit in that wr swing arm?

Any good on the yz125 or is it for restricted road bikes?

Hi all,

Going to 520 pitch on my dt just wondered what chain length is recommended? Thanks

How odd. Have you been self mixing up until now then?

A picture would help us see what you are seeing

My main job is a network engineer for a broadband firm.

We use mikrotik for our routing and netgear for our switches.

Cisco If we really have to but it's not worth the mark up.

How much did you pay just out of interest?

I picked this up -

lol not really sure what I had.

Welcome

Same frame colour as me. I like it

Awesome thanks @Calum

That's what I tried to fit. At the top of both rads there is an outlet to join them. On the yz there is a gape in the frame but on the dt there is not. I didn't fancy drilling the frame.

Evening all,

So how does the coolant bottle work?

Is it just an overflow?

I see that on the radiator the inlet/outlet is only open when the spring is pushed up by pressure?

Before I messed with my 2000 dtr build quality was great. The 3mb I think it was? Never let me down

Awesome thanks.

Only reason was with the yz engine i no longer need the oil tank and that leaves a massive gap. Not sure what todo ATM. The Lanza rad appears to be a rare beast.

Any suggestions on what to use for a twin rad setup on the dt?

Thanks

Thermostat stuck closed?

Thanks @Bentley.

What size is every one running on the front?

I've current got:

Front 90/90/21
Rear 90/100/19

I can't find a set that matches that. I can find an 80/90/21.

I can get road legal 90/90/21 but I would have to have mis matched tyres. Is that aloud?

Man I love that clear clutch case

Never even thought of a lithium battery. Thanks @CYBER-NINJA

I did have a look at the Michelin AC10?

What are like like on road? I was told they are dangerous due to then spacing of the rubber?

Hi guys I'm after some recommendations on some dirt tyres.

They need to be road legal but the main use is intended for forest/green lanes.

Size I'm looking for is 100/90/19

Any suggestions?

Thanks

@zrako I'm sticking with off road but I want to use the 19" rear

I'm keeping the stock arm and swapping the wheel hubs over just to keep the project going ATM. I did like the idea of the yz wheel adjustment on the rear as it looks smarter than the dt 1

Yz one is not wide enough. Tried this myself 2 weeks ago and gave up on that idea

I wouldn't bother with that. Seen them snapped quite easily. I would use a ground anchor and chain when at home and a chain around the wheel when out. Always try and chain it to something when your out. Remember even your own garden isn't safe.

When I lived at my parents we had a large garden with a dog that always barked at strangers yet one night I found my motorbike was missing!! Ran up the garden at 3am in my pants to find her resting at the side of the road on the kick stand. Guessing they went to get a van. I was very lucky

Any things can be done if your willing to spend the money. I haven't done that but I have a yz125 engine in a dtr frame. I needed to sort top and front brackets.

Don't you have paperwork? I'm going with 2000 dtr

Kick start kit - https://www.ebay.co.uk/itm/252747321086

@Zrako the guy made it out of alloy

The 1lx is up for sale

I've got a spare complete yz engine but in parts in a box. Do you have a picture of the gear you require? I can take a look on Saturday

This would work - https://www.smtp2go.com

We use this for temporary projects Etc at work. You get a 1000 free emails a month should do ok

Mk4 was hydraulic as well

My mk3 is my baby and she never lets me down. Got a ajq 20vt under the hood running 1.7 bar of boost takes lots of shit and make me smile and others surprised.

Used to have a mk2 I rebuilt but I scrapped that to try And win a girl back that didn't work doh lol

opps . how did that happen

@Calum said in mine DTR:

@CYBER-NINJA Better clutch feel, easier to use and the better ones are self adjusting. No more fettling the clutch perch.

If you have ever driven a Japanese car then you will understand. Most Jap cars from the 60's up come standard with hydraulic clutch. It's only now that the VW crew catching up.

just catching up.. my 96 mk3 golf has one

dam car thread i'm going to need to upload photos of my turbo mk3 now

@Zrako calum's method works great. i've got some close up pictures so you can see how it works

https://dt125r.co.uk/topic/595/project-i-can-t-leave-things-alone

i used a stock dtr lower bearing in the frame with the yz forks and the stock yz top bearing sat in the new bearing cup

is there and email server configured?

when i subscribe to a thread i don't get an email.

i have checked in my junk box

My stock dtr would top out at 60 on stock brackets. That wasn't quite max revs but with all the noise I didn't dare

What would you say the perfect colour is? The plug must be oily if it's dripping from the exhuast

Looking good

Any tips on doing a rolling burn out? I've never done one and been thinking about giving it a go on my drz

What ratio would you run?

Ok awesome thanks guys

Hi all,

So I know the basics of 2 stroke engines and I know the crank is oiled by the stroke oil.

My yz engine doesn't have an oil pump and it's self mix.

I'm assuming not all 2 stroke road bikes have always had a oil pump?

The reason I ask is because a guy I was talking to today reckoned I would be in trouble using the yz engine on the road because it would have a lot of overrun/coasting down hills and in traffic etc. He seemed to think that it would blow up rather quick as the crank would be dry.

I know some oil will get onto the crank with the idle ammout that's aloud to pass but will this be a problem?

Also what ratio would you guys use on the road? I don't mind a bit of Smoke and I also get a bit excited with the throttle.... every day.

Thoughts would be great

Ok man thanks.

I've got a guy in mind but I thought you might be with a try as you've done one before

@Calum did you see my post about the bearing cup?

Hi all,

My names Gareth and I'm 27 from the Isle of Wight, uk.

I've got a dt125r 2000 and a drz400 2006

I used one of these that I found on uk eBay

http://doctorenduro.com/index.php?main_page=top_mount_led_tail_brake_light

Hang on so the old light is working?

If you cut the 3 wires at the same time when power was applied chances are you've blown a fuse. I'd check them first

So neither bulb is working?

I used a hel set like this with no problems - http://www.wemoto.com/bikes/yamaha/dt_125_r/88/picture/hel_front_hydraulic_hose_-_standard_set-up/

Be careful with discs I can't remember what type it was but once I went for a cheaper disc and it would rust over night where as the more expensive ones didn't rust at all. Sorry not sure what the coating was called

How odd. My 2000 dtr had no problems at all. Is the headlight dim as well? I'm wondering if there's a problem with the voltage regulator.

@Calum i'm also attempting to put the yz125 forks on my dt125r.

would you be interested in making another bearing cup for the top bearing that i could buy from you?

Evening all,

Has anyone fitted a yz125 or wr400 swing arm to their dt125r?

I've seen the wd200 swing arm fits but they seam a little hard to come by in the uk.

Thanks
Gareth
