I just received my new polaris 800 cylinder using a cylinder exchange program (nicasil bore). I took the cylinder out to take a look at it and I noticed some small holes in the nicasil bore, three to be exact. For the life of me I can't imagine that this is ok. Anyone know if this is normal?? The only reason I did a cylinder exchange is because I noticed a small hole in my old cylinder after the piston had seized. If you were me would you return this cylinder and ask for another one?? what do you think?
