Need to know piston to bore clearance, large air cooled 2 stroke.

[TheRealFatShady]

Does anyone know the piston to bore clearance for a 90.5mm Wiseco piston? I'll actually use it on my 1982 CR480 (air cooled, same piston as the 500's) cylinder, but I need to know that clearance and maybe end gap.

Didn't see it on Wiseco's website, and it wasn't packaged in with the brand new piston.

Thanks

i'd shoot for .004"

Alright.

I know DC has mentioned the air cooled 250r's needed a large gap (I believe .006 or .007) but I wasn't sure if this would need to be that large or not. Getting bored in the morning, so thanks!

Stock specs, not sure if this helps with your Wiseco.
