Hi all, My bike developed a weird rattling coming from the clutch basket, I think. It stops or minimises when I pull the clutch lever. It is not that annoying but I would like to ask if someone has experienced this and what could the cause be?

Can anyone recommend a good fastners set that is availabe in the UK? I'm talking a big box of nuts, bolts, washers etc that I can have to hand when I need to replace one of the rusty ones that are beyond saving on my bike. Seems like there's always at least one like this that needs replacing when I've done any...

I'm kicking myself a bit for this one, but let's see if I can get it running at least. Low compression (45-50 dry), no spark (before me), new wiring harness and tdi box installed by questionable methacanics... Leakdown and simple tests indicate carb, valves, rings, or something bigger.

Exhaust cracked right through today 😟. Don’t think it can be repaired ? So looking at new one . What do the new stainless ones sound like ? Good or too loud ? Keep it standard ? Thoughts ? Cheers

I noticed that the shorty header pipe is touching the oil pipe bolt on the right case cover. Could it cause any problem? I don't want to undo the header bolts unless absolutely necessary because one is helicoiled and if it fails the repair will be troublesome. Helicoil cannot be used again...

Hello everyone. I recently bought a used TTR-250 raid. After a while i noticed that if the bike was left being off for more than 20 hours i would have hard time firing it up again and also i noticed white smoke coming out of the exhaust at high revs (burning oil was my guess). So i decided to do a top end rebuil...

Hi All I ride my TTR250 in the dusty outback of NSW Australia (Cobar).
