Lovely pic yes, really summarises biking to me.

Lucie - you put one 1100 piston into a 1000 block 3 matched. one odd one? same liner, just bored one out oversize ?

Are you getting vibration problems at all?

It is a 81 kz1000 j bottom end. an 81 Kz1000 head. A 84 GPZ 1100 jug, 1100 pistons from a different GPZ, and the cranckshaft is unknown. Although we do know it is not KZ. the wrist pins are to small.
Over all is it five different motors combined into one.

Not vibration issues. (It runs Strong and fast) I have faced a variety of issues this season from a clutch cable to oil leaks. But its a process I suppose and she gets better and better. Winter has set in here in Utah so she is all back apart and work begins again!
My author site has some stories about the bike if you are interested.
