nsr 125 top end rebuild, corroded pitted marks in cylinder

[themuffinman]

hi , ive replaced top end with new pistons and rings, ive noticed above the manifold port in the cylinder is 3 minature tiny corroded pitted marks, ive put the engine together and the compression is good,
how long will it last?
ive still gotta swap it over into my nsr , because the engine im useing in my nsr is gettin kinda tired, (it can still hit 95 with ease though )

and apart from the 3 pitts the rest of the cylinder is very good , still has the honeing cross hatch pattern on it
