Being a mechanical klutz, I send the bike to a mechanic for anything non trivial.
It's approaching 120,000 kms now and the valves have not been inspected for the past 30,000+ kms, the brake and clutch fluid need changing, my BT31s are at the end of their useful life (nearly 18,000 kms), and I need a new chain and sprockets after 43,000+ kms.
The bloke I've been going to has moved on to other things, so I found a local chap—which is good because I can walk home after dropping the bike—and left the bike with him late on Wednesday so they could do everything on Thursday.
About 3.00 pm on Thursday I got a telephone call from the workshop and, even while we exchanged pleasantries, I could tell the news was not going to be completely good. After a brief conversation and dispensation from my wife, I leapt (in my dreams) in the car and went around.
The "special bolt" (part #90037-422-003) and accompanying washer (part #90459-438-000) had worked their way loose from the end of the countershaft comp (part #23220-MGC-000) and vanished somewhere along the road. In so doing, they'd punched a hole in the Cover Assy., L. RR. Crankcase (part #11650-MAZ-010) and allowed the sprocket (part #23442-MS2-610) to slide in and out along the countershaft.
The top of one of the internal screws (part #90118-MR1-000) had been partly ground away by the chain and it looks from the photos below like the chain (which was to be replaced anyway) sustained some damage as well.
Here (courtesy of the mechanic who worked on the bike) are some pictures for your entertainment.
