Sorry, the psi went from just under 130 to over 180...
The cylinders were measured and are in spec. They are being honed and flattened right now. I just need to figure out rings.

I think you are going to have a problem trying to get old rings to reseat in a cyl that has been honed,
the rings are very hard to find, I got a set on fleabay and they were over 200 bucks.

you didnt say weather you were going to have the head done or not, at the very least you need to replace the seals and lap the valves in,, you can also reshim them at the same time

Oh, just get the Wiseco 720 kit and get a bore job. It will be worth it.

I saw an overbore piston ring set for the 650 on fleabay for $350 a couple of days ago. If rings alone are going to be $200, the extra $150 buys you a whole lot.
