DT125R FORUM

@Stevie-Wonder Yay! Congrats dude! Welcome to the big boy club!

Aww, that sounds sick. I live near the Forest of Dean which I imagine would be endless fun of cycling round there. But I've never been as I don't have anyway to transport push bikes over to there (40 ish mile). That does sound like hard work though, just keeping the bikes riding nicely

Replacement

Unable to log back in had to set up a new account

I have tried another CDI still no luck. No servo cycle and no spark. I have tried three different stators and same result. Because the replacement bits I .trying are second hand I have now way of knowing if they are ok. Is there a way to work through the bots one by one. For example can I connect the servo to the battery somehow to see if it works? I can turn it by hand so it's not seized. I don't understand why servo and coil not working. Please help.

Any decent fan kits to mount to the radiator? Adjustable thermo activated switch, shrouded to pull air through from the rear of the radiator?… I’ve got some work to do first, there was oil scum in the radiator and I guess all the way through the thermostat, pump and system. (I’m wondering if the stat is all gummed up) The pump rotor and seals were replaced when I rebuilt the bottom end… It’s not the head gasket blowing though, it’s not pushing coolant into the expansion tank or noticeably lowering the level in the radiator. I had problems with a slight step in the casings at the rear of the barrel which I thought I had fixed. There’s a ‘wet line’ between the barrel and inlet manifold that seems to support my theory. I’m waiting on a new genuine base gasket, thermostat and some Loctite VHT copper RTV sealant, as well as the thermostat and gasket…

I’ve tried another cap ( an old one that came with the bike as the bike came with 2 boxes of parts) and it seams to be worse so I think that shows both caps are bad and the og one wasn’t as bad Thank you very much

Okay...so some overnight parts from Japan and CMSNL and some others from Australia I've finished the gearbox rebuild.....

This completes the output shaft rebuild.

[image: AP1GczNkYj3ORIWqQl0xC4kYfaZyJ1ywJV2dfvlihCnch34e7OrCJ1hJIc1Oh9EXyTvIBN8FWkZxZgKaWRp0BakEPsrsPAWWkLHEcPGATSnyyucBAsdvVx3W-xukLygatC3vIlJjx5vrvCrE_pRhpFoyG6KT=w1922-h928-s-no?authuser=0] Should go without saying, all near bearings and a lovely carbon fibre chain guard which I bought about 5 years ago for the Raptor. I'll probably keep the Raptor bone stock and therefore it's not needed for that project and can go onto this beasty. I did have some swinging arm spool spacers machined up but for the life of me I simply cannot find what I done with them. No doubt they'll turn up eventually.

@HOTSHOT-III No, I believe it's a Yamaha DT230 Lanza arm. But yes it's like half the weight of the original one I had. I just need to get the right parts machined up to fit my wheels etc. I've been so spent on 4/5 other very expensive projects that I just haven't bit the bullet yet to order the machine shop work. With regards to mudflap where, I'll probably design some sacrificial item in CAD and 3D print it. @RikuRo I've sent you various links. Any DTR from 1989-2004 will do.

@Challenger very nice build, may I ask which wheels these are and what size they are. I presume they also fit the dt125r swingarm and forks?

@somerandomguy314 Really? I am sure that's not the case, I sell to EU all the time through eBay's Global Shipping Programme. Ask the seller if they'd enable it, it's invisible to them and they just ship it to a UK Warehouse.

YAY! What has been, three long years and the bike is finally on its own two wheels again. [image: ILujNIK.jpeg] Trip down to the powdercoaters to pick up the suspension spring as it just didn't feel right to put the crusty one on there. [image: 2aP5114.jpeg] I had it repainted the OEM colour for this bike, but fitted the RX/MX/SX shock absorber. It was refurbished to the best of my abilities. [image: 2QH7PxV.jpeg] Sadly the bike isn't concourse and never will be. [image: 1CoLTaZ.jpeg] But it's starting to come together nicely now! [image: 7k2txzW.jpeg] And at least I can move it around the garage out the way of the other bikes finally! [image: V9jlvnt.jpeg]

@Bilbo9000 Outstanding, I never thought of doing that! Well done Sir

Thank you very mutch, i will be looking for one of the Athena ones. I have managed to get hold of a 3bm head but it is badly damaged on the inside so i will send it back and switch it for a Athena head.
