ish Posted December 30, 2005 Report Posted December 30, 2005 I Blew the top end on my shee. it was at .090. some ppl have told me not to go to .100 cause of overheating issues. just wanted some advice on if that is true or not. Quote
Banshee17Racing Posted December 30, 2005 Report Posted December 30, 2005 I've heard of people going to .100 over. But you're making your cylinder walls paper thin. I'm pretty sure .100 is the limit. When it blew, what happened to the actual cylinder walls? Even if you can put it back together with a .100 bore, I'd start looking for some new jugs/sleeves or possible a cub motor for next time...

RNBRAD Posted December 30, 2005 Report Posted December 30, 2005 Don't waste your money, get some new(er) cylinders or the cubs. Quote

race-a-holic Posted December 30, 2005 Report Posted December 30, 2005 Might want to see how much it will cost to have the sleeves installed.Might buy a set of used stock cylinders.Shouldn't be hard to find.Alot of people have switched to cubs. Quote
banshee tuner Posted December 30, 2005 Report Posted December 30, 2005 Getting sleeves installed will cost you big bucks, but your back to stock bore and have a several rebuilds left so in the long run is not a bad idea. Cost wise you will be better off buying another set of cylinders. Quote
brilei5 Posted December 30, 2005 Report Posted December 30, 2005 If you sleeve it you dont have to go back to stock. There are always big bore sleeve kits. The labor should be no different and I beleive you can still bore big bore kits 3 to 4 times for rebuilds. You will also have to go to big bore domes,if you have a cool head, or have your stocker chambered. Cubs do seem to be the way to go though If you got the cash. Quote
blueshee03 Posted December 30, 2005 Report Posted December 30, 2005 its true when the sleeves are that thin the motor will run hotter quicker and it makes them unreliable.if you decide to resleeve your cylinders go with the standard sleeves rather than big bore sleeves because you will need either a coolhead with big bore domes or get a stock head modded.in addition unless you have ports and transfers redone and have the right pipes it won't run any better than if you go with standard bore sleeves.just installing big bore sleeves without the portwork can actually make it slower than a properly tuned stock bore.i'm sure there are a few builders on here that would be glad to discuss it with you and help you decide which way to go.my own personal preference is "passionre" on here.he is always willing to help wether you want him to do motor work or just want his oppinions and suggestions.you can call him also if ya like 918-232-3950 Quote
