bit of a clunk going into gear, but i think that may have just been first start with new oil - changed to fully synthetic 10w/30 as its done a few miles now.
clutch works ok but after about 10 miles i noticed a bit of a whine in 5th & 6th,,,, then 4th, then all apart from 1st/
when i roll off the throttle it goes, put power back on and it's there again.
so i think i can safely say my gearbox is well and truly on the way out.
last 2000 miles or so it's been randomly missing gears and jumping out so at first i suspected the selector drum or fork worn or shitted up, as in needing oil change (usually first sign oil needs doing is i get a bit of clutch slip)
the whining is indicative of a worn shaft or bearing.
the fact that it's there in every gear, under load, and constant with road speed not engine speed, makes me suspect it's the output shaft bearing, which i can understand as it wouldve took hell of a knock when the chain snapped and smashed the casing...
hopefully it either goes away or lasts a few more weeks til i get new bike.
then it's getting put away until new engine is built up.
cba stripping it down just yet, but will do once new arrival arrives

pics should be interesting.
