Hi,

Small little step. Just finished re-painting the cylinders.

Hi,

The crankshaft I am going to mount in this engine is not the one that was originally there, so I removed out the clutch basket that was on this replacement crankshaft, and mount the original clutch basket on it. The reason is because apparently to avoid extra noise, is good to keep the clutch basket with the original other gears if possible, and in this case it is possible.

More soon.

Hi Hugo, it is a little late now, to advise you to never hold a crank in a vice across two flywheel discs, as this can knock the crank out of alignment. Only ever grip a crank by a single flywheel disc, that being the one which is on the shaft end being worked. I have seen a perfect shaft fall out of alignment by as much as 0.010", especially where the removal or tightening of nuts was involved or bearings being replaced.

Hi Ian, I know, know, I really hope it's not out of alignment. I didn't tight much, so I hope everything is in place.

Aiaiaiaiaiiii
