Well the worst has happened.My cylinder is trashed as is the piston.Mechanic says it will probably take at least a .30 overbore to get all the scares out.Well Im getting a wiseco piston.Does anyone know if I will notice any performance boost, and should I get a compression piston, or what?

 

I did mine recently and notice a small improvement. Do not worry about .30 over because my cylinder can go up to .80 over.
