Progress

Gearbox out, cranks out. All that is left is the pilot shaft and this can be removed with the engine on the bench.

Stripping it down

Gearbox out this morning. Trying to make sure everything has a place,  and I don't lose anything!  There is a really small o ring on the gearbox output shaft that I nearly missed!

aaaarghhh engine cracked!

And there I was just sitting next to the bike contemplating my next move, when my eye was drawn to a mark on the rear engine mounting.... rub, rub..... no that's a crack - F#$K!

Yup the engine casing is cracked at the rear engine mounting point.

I am pretty sure that wasn't there before so this is probably down to my last accident, although I am not quite sure how this could happen. There were no visible signs of damage to the frame, so the only way this could have happened is if the pressure on the footrest hanger was enough to flex the frame inwards thus putting pressure on this part of the engine.

Still it's done, what do I do next? The engine is held with a big lump of casing as you can see from the photo, and the bolt goes all the way through, so I am not sure if this is really serious. The sensible thing to do however is to strip it down again, and get this welded up. Which is a right pain!
