Hi every one was wondering if anyone can help me wile out on my ttr every thing was going fine until I started having trouble changing bk down the gears then I ended up with no gears so ended up pushing the bike home and after a good jet wash I managed to get bk some gears but wilst in gear it sounds like the clutch is sliping so I'm mow stuck wondering is it the clutch or gearbox.
Gearbox problems on the TTR are very rare. More than likely the problem is with the clutch which is why you got some drive back after the oil and clutch plates had cooled down.
Is there free play at the lever? If not, adjust until there is and see if you get back the drive.
