....I couldn't stand the tension any longer and started to dismantle the 600cc motor. The culprit was not a roller bearing but a dowel pin holding together the clutch basket. The casing is damaged at the output shaft bearing and there is a loss of stiffening ribs - I already prepared a new casing from with new bearings to swap all the internals of the damaged motor.

...now I'm in the rebuild process of the motor. Why am I so slow? Hopefully the upcoming spring will accelarate this. I've found a good motor casing om a 350, changed the bearings, shimmed the gearbox and crankshaft and all the other shafts. I also checked the timing of the cam shafts. I've put the equal opening of the valves during overlap one degree in advance to TDC - any comments on that?
I also lightend the clutch basket and found it out of balance by 10 gramms, which I eliminated by boring additional holes...

...indeed - I've tried a comparable approach - actually I was not happy. The motor did not run as intended. The timing of the second cylinder was not right and I returned to the two pick-up set up. Funny thing is, the identical ignition set-up works perfectly in the Alazzurra of a friend and co-author of our ignition development- never found out why...
