Hi grumpy,

I'm going to oil all the bearings but fortunately I won't have to reassemble the connecting rod because I never touched it; I just took out the piston, gudgeon pin and the needle roller bearing (shown in previous pic) which goes at the end of the connecting rod. The gudgeon pin goes inside that same needle roller bearing.

I am replacing the piston rings. Basically it will be all the same old parts except for the new piston, piston rings, circlips and gasket (all these are new parts). So what is the break in procedure? The cylinder will still be the old one. You mentioned to clean all the alluminum shavings from the bore; I put some carb cleaner and flushed and wiped with a rag, is that enough?
