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 |
