Hi,
I’m rebuilding a Minarelli V1. It’s the earlier version with the stub plane crankshaft. I think it’s from 1975.
For the life of me I can’t find the magneto side crankshaft shim. At first I thought I dropped it somewhere but I looked all over the place and it’s nowhere to be found. I’m usually pretty anal with motor parts and always place them in order in a tie-wrap. I’m pretty sure that if it had fallen somewhere I would have noticed it. Is it possible that there was no shim from the start?
The crankshaft 6203 bearings were FUBAR rusty and the traces on the crank match the bearing inner races on both side.
I measured both the old and new crank with a digital calliper and they both measure the same, +/- 0.1 mm (the new one measuring less, IIRC). How much tolerance is acceptable in a V1? And how to I tell if the cranked needs to be shimmed once the case is closed?
Thanks for your help!
