I have a 1993 sl750 that I want to replace the pistons and rings in. The Polaris factory service manual says the bore is 69.72 mm. The Wiseco replacement piston (WK1075) says the bore is 69.75 mm for the std size.

Does anyone know what the correct size is for the standard factory piston and will the Wiseco pistons fit?

Thanks
