I have a kx80 t1 big wheel and the bike was in pieces when I bought it. There is a tiny tiny little nick in the cylinder just under the bottom of the exhaust ports. When I say tiny I really mean tiny. How worried about this should I be? I really cant even feel it with my finger. Will a new piston and rings be alright?

It would be good idea to drop in a new crankshaft with main bearings and seals
And as CRazy250 said but that depend on cylinder you have and should beware that some have Nikasil Plating so do not do hone job sent it in for Nikasil Replated
