Im rebuilding my 06 this winter top and bottom end and i was wondering if i should put an oem piston in or a wiseco? Im going to run stock compression so would there be any power difference? Or reliability issues with either?

Oem is the only true safe way to go IMO.

If you are going with stock compression then there is no advantage to running anything other than OEM. OEM pistons are forged for these bikes, but cost half as much as a forged Wiseco or similar aftermarket brand.
