I tried the stethoscope method. It worked well. There were obviously noises coming from the gearbox but they all sounded like noises that should be there. Nothing out the ordinary and no major rumblings, certainly no crushing sounds.
Shaft seems good, no noises from there either. The screws holding it to the plate on the gearbox are all there and tight. (I did re-use them when the shaft was off in Thailand - I knew it was bad but couldn't get any others. I thought this was probably a small crime)
I used the stethoscope method against the bevel drive and that IS where the noise is coming from. It was very hard to pinpoint the noise by ear alone, would have sworn it was gearbox end but with stethoscope it is clear its bevel drive end. A knocking, very audible when doing this. No real ryhthm to it. Bike was on stand but in gear with clutch out and wheel turning. Seemed irregular. Dont know if this could be classed as normal considering the bike was on stand (swinging arm at unnatural angle etc) or whether this spells trouble for the final drive.
Thanks for assistance so far anyway.
