Has anyone done a 100mm Piston in their WR?

I wanted to know if I had a cylinder bored to fit, if I could install the 100mm piston?


Do I need to have the cases "modified" for the piston skirt to clear?

I cannot find an answer to this question anywhere. I was hoping the knowledgable folks here would have som good information.

Talk to the company you plan on getting the 100mm piston from. They'll let you know if cases have to be modded or not.
