When I had Kawasaki 2-strokes, they could not be bored. Dont know it was changed. Its been a while. However you should be able to have it nickelsilled or resleeved.

You know how much that would cost?

I've had several modern 2 strokers done.. you're looking at around $200 +/- $30-40 depending on who you have do it. If it were me, I'd simply get it re-sleeved because in the future if it were to ever get scored again, you can simply bore it. But with the nikicil it can't be bored and you'll have to get it re-sealed. To each their own though..

Well i looked at eric gorr's website and it looks like he says you can hone it??? The cylinder isn't bad that i can see,just a little rough.

Yes, you can have it LIGHTLY honed or you if it is very light you can try to get out the scuffs with a scotch bright pad (green or brown) - steel wool doesn't work.

yep i would have it honed first and if that didn't work i personally have it re nicklesilled. less friction, gets rid of heat better, lighter but with a sleeve you can bore it if it blows but with good maintenance and parts it shouldn't happen.
