Need some more umph.

[PolarisRider]

I think my 300 needs a little more power. I would like to install a high compression Wiseco piston. Now my question is, is it worth it to bore it or should I leave it at the stock bore with a 11:1 compression? If I should bore it, what bore size?

[PolarisRider]

Umm, bump.

Bore it only if you need it.

You may or may not need to bore, it will depend on the condition of the cylinder. The most gains will be from the higher compression piston and cam.

What cam is good for a pipe and a high compression piston?
