Yes, the stock cylinder has a nicisil coating. It's very hard. If it's got ring problems, I would up grade to a 11.5 . You can still run pump gas and it will wake the bike up.

Stay away from the big bore sleeved JE kit's, they are trouble. I've seen the cylinders sink in the jug and start blowing head gaskets. You can fix it but why do if you know???

I guess I should of said almost every one that I've talked to that has one , has or is having trouble, one kind or another.

Either that or I'm just (The Help Net Hot Line) for those who have them.

I doubt you are the normal istaller either.

yeah that seems to be the all around consensus of the 720. I've made up my mind. I Talked to Eric and im going with his 730 cylinder. I just dont think you can go wrong with it. I apprecate all the Help

A well built stock bore runs very strong.
