Kawasaki KR150 cylinder sleeve?

[JustHarry]

Hi guys. i have recently(today) rooted my kr150 cylinder and piston. i put the piston in backwards and the rings got a little intimate with the exhaust port.(im sure you can imagine what that does to the cylinder wall as i cant figure how to upload pictures) i have one option of resleving the barrel. have any of you done this before. whats involved and what sort of sleeve did you use. i have a friendly engineer neighbor so that makes doing the sleeving a little easier. what do you think?
or... is there any kr150 engine bits or parts bikes for sale around?

Cheers Harry

I had NZ cylinders do work on my cylinder, have a look at there webpage, i am sure they could fix it,
