Gearbox rebuild needed!
Permalink  
 

i was out riding on sunday with some mates and we stopped off for a while,

started bike up left it warm up for a while, go on popped it in first and this noise comes along

doesnt make the noise in all the gears but does in neutral? 

heres a video of me turning her over with a drill with the clutch off

youll hear it about half way in.


so i know ill need new bearings throughout the gear box but what bearings do i need and if what else??

thanks guys

it can be a common failure if the crap int cleaned from the rear of the sproket it ruins the seal and lets dirt in and wears it out
