Hi I have recently had the sprag clutch on My TTR replaced as there was a noise when you switched the bike off. The mechanic that did the job said there was significant wear on the sprag you could rotate it both ways before it would lock up. The Boss gear he said had a little bit of wear but he didn't think it w...

Hi all, I have a couple of questions relating to the TTR gearbox, hopefully the collective genius of the forum can help me! I've had a couple of occasions recently where I get stuck in first gear. Gear changes on the low gears can also tend to seem very stiff / like they are not engaging properly. Higher ge...

I thought it might be interesting to post up some of the TTR nasties that I have come across so that worse case scenarios can be viewed. Please feel free to add your own. First off, how about this for a home-made timing chain tensioner? Or a delaminated standard case saver? Or a valve seat that fell out?...

Hi Occasionally my TTR would make a clunk when you switched it off perhaps once in twenty times. Just recently this seems to be getting more frequent so much so that I have just come home from a Dales ride a day early as I didnt want to do any damage to the engine having just rebuilt the top end. I guess now it...

My 04 blue plastic tank has become completely non-gas (as in vapour, not as in American petrol!) proof, which I think is due to ethanol in fuel these days making the plastic go porous to gas, as detailed on other websites. The OE stickers bubbled off and new stickers soon followed. The tank is complet...

Okay, a may be being stupid here but I'm having trouble getting the old link out. I have removed the rubber bungs and removed the 17" bolt but cannot get the bolt/sleeve to budge, the old link moves freely from side to side alright. Is there something I'm missing or doing wrong? Any help appreciated.

Hi, My friend's TTR has bad noise coming from cold engine only. Please listen audio recording from 7s: https://1drv.ms/u/s!Ar9YNbdz-p-shJpNFEbPR-5GBH0iBA We suspect automatic tensioner. The camshaft chain was changed last year. When engine is wormed the noise is gone.
