2003 Yamaha Dt125R Project

@Calum well i say that what i mean is you can change the top bearing to taper bearings instead of the standard ring bearing

[Calum]

@Walney-Reptiles Not without changing the the yokes/bearing cup.

I done it cause I fitted USDs. But otherwise, no. Or I'm sure it could be done, but what would be the point?

[DTR+NSR]

@Calum my dt is fitted with tapper bearings top and bottom with out modifications, tapper bearings are able to cope with greater loads so generally last longer.

[Calum]

@DTR-NSR Cool, hit the geezer up! I didn't know it was a thing.

My DT was stolen and ramped. Forks bent, wheels bent, bearings in the head tube was fine. They are robust enough. Obviously Taper has its advantages.

[Walney-Reptiles]

Well i have made some more orders list below

Head race bearings
Linkage bearings and bushes
Rear swing arm bearings
Frunt wheel and Rear wheel bearings
in total £186.59

Heres a list with everythink i have bought since i started the project back in july including the above..

Athena 125cc cylinderhead kit £429.95
All bearings in engine (SimplyBearings.co.uk) one from pjme £128.09
All bearings on frame and wheels (coming from ebay.co.uk) £186.59
Athena full oilseals (from ebay.co.uk) £33.95
Athena Full gasket set (from ebay.co.uk) £29.99
MSP (replacment bits for inside engine that i lost) £45.48
Sub Total £854.05 SO FAR

I estimate there will be atleast £600-£700 more ontop left to be spent before it is complete

[Calum]

Oh sweet bud. Sounds very expensive, but if its a job worth doing it's worth doing right.

[Walney-Reptiles]

@Calum I agree there mate, I will be getting a new carb ANY advice on carbs? im not after the cheapest one or the most expensive one also i will be getting one of them zeeltronic CDI's for my bike but id like to know if anyone on here has set one up? currently i have the 3RM-20 cdi units would the zeeltronic CDI replace that? i also use the PV System.

[Walney-Reptiles]

So i have Just ordered some more bits...

Yamaha WR125X Radiator With 12v fan (Im going to fabricate my own mounts for this so dont worry if you think it wont fit ordered this because my DTR one is Crap and the wr one was only £32 with free postage)

Also ordered
a second Rad fan witch was £18
DT125R Stainless Engine mounting allen bolts

Just an extra note im going to cut the elbow off the bottom of the radiator and spin it to point the correct way

[Walney-Reptiles]

@Walney-Reptiles where’d you get the linkage kit from pal?

[Walney-Reptiles]

@Walney-Reptiles don’t suppose you could measure those linkage seals for me bud?

[claws]

@Walney-Reptiles well with your setup i would recommend some 28mm - 32mm carb. for example a mikuni tm28 or a keihin pwk 28. im running a keihin pwk 36 on my dt but i have a 170cc kit on it. its still too big for the bike
