Also, I forgot...You will need to use the 85-86 head gasket to compensate for the larger bore.
With the 87- gasket , the bore hole will be too small!

The piston that you are asking about is:Wiseco Part#: 722M06970
The piston is 1mm taller so you will need a couple of base gaskets or cut the head because the piston will hit the head.
Also, you will need to modify the piston skirt.

It's getting to be about my last bore, does anyone remember what pwc piston was used in the 270 kit?

Also, what's a starting point for jets for. 87 250 with fmf, boysen, and Keihen 39mm

Thanks.
