Can anyone suggest the optimum clearance on said bike using 1mm oversize wisco piston. I know there is a size written on the box but had varying advice since.

Any suggestions??
Many tahanks.

The bore should match the number. The bore should be 86mm for 1mm over. The piston will be undersized from the factory. It will be .004in clearance or .05mm
