Piston size? to get a 330

[ben41884]

I wanna get a wiseco piston kit and have my 300ex bumped up to a 330. How much oversize do i need to go on the piston? Thanks much

that may be a 81mm piston,do a search i have seen that topic before though.i dont feel like doing the math..:D

80mm is the 330.

Well then I guess mines a little higher than a 330, cause I am pretty sure I have an 81 mm piston. Call Four stroke tech, they will hook you up with what you are looking for.

81 would be a 338 on stock stroke
