I think that a good fiber gasket would work. I have a friend with a 703 with a copper gasket and he cant get it to seal right. I think using silicone or gaskit cint is not the way to go. If a fiber gasket could be made then it would solve all these problems. Needs a smaller fire ring but you would have to put a sleeve in.

Well I'm kind of bummed out now. [img]i/expressions/face-icon-small-sad.gif[/img] I thought that I could have the stock sleave bored and replated and it would work, I guess not? Well that suck's I will just have to save more money or something, What about boring it 102mm over and having it replated? Then would it work?

Yes, you can bore it to 102mm and re-nik the cylinder. [img]i/expressions/face-icon-small-happy.gif[/img] - That would be a 680.
I think others have gone to a 103mm bore and re-niked the cylinder (is that one of the components to the Sam Coe 730 kit (also stroke?)
I think 102mm is the largest Team Pami will go on the stock jug (if that helps with your decision.)
Gary at TVI may have done other things as well.

I am back from pismo and all is good[img]i/expressions/face-icon-small-happy.gif[/img], the 720 ran GREAT. Also you will need the RWR 60% clutch springs, my 40% springs did not hold up. I had no overheating or mechanical problems with the engine . The power was great, but I think you could get alot more top-end with some larger valves. The one problem I had was my carb kept slipping off my ported intake[img]i/expressions/face-icon-small-sad.gif[/img] If any one has another stock intake forsale PM me.
