I have a 91 kx 80. The bike was in pieces when I bought it. My question is that there is a tiny tiny nick right under the bottom side of the exhaust ports. It is smooth and i cant feel it with my finger. Did I say tiny. Someone told me to just buy a new stock piston and rings. Will the new piston and rings be all right in it and how much if any compression will I loose at the bottom of the stroke.
