I love this forum as it appears a great number of you are in the UK. I'm getting ready to tackle my fork seals on my 99 TTR. I have the factory service manual specific for my model. It's a 250(L)C, a California trail model that got a conversion kit. There's very few of these on the road here in the US...and I li...

I'm suspicious that my cam chain is loose, what are noises that signify a loose cam chain? Or is the cam chain self adjusting?

Google translator Sorry for the question but this is my first bicycle with a hydraulic brake. I took off the front brake, the wheel is free. When the caliper is fitted, the front wheel is difficult to turn. How to fix it step by step? Thank you. -- Edited by tom13 on Saturday 4th of April 2020 11:14:10 AM

Hey all! So I bought a totally junked 2002 TTR 250 for dirt cheap awhile ago and have been slowly rebuilding it.

In the picture below, you can see that I have the starter wire attached to the top of the star...

Hello, I’m hoping someone can point me in the right direction. The tank on my 2001 Ttr250 was cracked pretty bad and I tried to repair it but in the end I wasn’t successful. It has spiderwebbed cracks all over and when it has gas it expands and they explode. Do any of you know another tank that will fit it...

Hi, I seem to have a random starting problem on my '93 Raid. Sometimes when I press the button its completely dead, its not the battery because I can try it again 10 minutes later and its fine. All I can think its bad contacts on the starter button. Any other thoughts would be greatly appreciated.

On the subject of rebuilding the rear shock, has anyone ever removed the restrictor needle that is in the shock shaft? Does anyone know which end of the shaft it would or should come out if indeed it does come out at all. There is supposed to be an o-ring living in there from what i can gather but that is all i...
