Hi Houston,
Got a few questions regarding engine hopefully you can answer.
I have a novarossi bonito and have it stripped but want to know when is it considered necessary for a repinch of the sleeve? I have about 3.4mm clearance from the top of the piston to the summit of the sleeve when the piston is pushed into the sleeve.
Also the bearings.... What are the tell tale signs you need to change the front and/or rear bearings? I don't want to take them out of the crankcase for them to be ok so is there anything I should be looking for while they are still in the crankcase that would flag they are worn out?
