I have one very badly scored cylinder, and the piston shows the same. The other cylinders probably need honing and of course there is wear on all the rings. Everything else looks good.
I don't know if the cylinders can be "re-sleeved" or if I will have to buy all new ones. I think I have to get all new pistons to keep them in a balanced set. I don't want to "over kill" it, but do want to do it right. See N64KR at http://KRBuilder.org - Then click on the pics See you in Mt.
