Hi guys, Small problem with the compression damping clicker on the reservoir of the rear shock on my bike. It doesn't like to turn or click It rotates a few degrees either way but seems to be pretty stuck and I don't fancy forcing it. This is the closest picture I have of it currently, any ideas as to whats u...

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?...

What is this seal? Is it a seal? It's not shown on the Yamaha Parts Finder microfiche that I access on line. I forgot - 2002 TTR in Oz. The bolt behind drains the oil from the left side exhaust cam well.

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.

I'm looking to replace the bolts on my 1993 OE. Is there a quick guide to the bolt sizes anywhere? Also any advice on purchasing a bolt kit would be greatly 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.

Hi guys, hope someone can help, my ttr keeps blowing the 15amp fuse on top of the battery box, which then kills the engine. Change the fuse, bike starts, will do 100m, and fuse blows. Will tick over great, but soon as a bit of load.....fuse blows. Any idea's please? Thanks in advance, Steve.
