help on shee cylinders

[nitrousbaby]

ok I got a set of cylinders ran them for about 6 months, they just started burning antifreeze so I changed the head/ gasket took it for a ride and its still smokin white out of the left cylinder Im thinkin cracked cylinder but thopught Id through it out there to you guys any other sugestions ? and how would I check for a cracked cylinder?

The base gasket could also be blown. It was blown on my zilla and caused the bike to smoke.

It's possible, that the head is warped, and needs re-decked.

Ive used 2 different heads a cool head and a stocker, and the base gasket could be a issue but I didnt think the coolin jackets went through the bottom on a shee.....

I would pull the jugs before running the bike again. Not only can it suck coolant but you could have an air leak and then you will be in deeper doodoo. John at RJATV can get you a gasket kit cheap and fast.

coolant doesnt go that far by the base gasket on any 2-stroke cylinder

i would say that teh cyinder is warped on top and needs to be shaved some how
or new cylinder

Your right they dont.. straight edge the cylinders to make sure they are sitting flat on the case after that maybe puting some denatured alcohol in the water jackets while the jugs are off and see if it leaks down....sorry only suggestions i have unless your case is cracked and it is some how pulling coolant into the crank? the only true way would be to have the stuff magnafluxed

thanks Ill call flannery today and see how much to magnaflex it man I would rather it be a case then my cylinders I got some dough into the porting on these cylinders...

If you have the option to magnaflux them, there is no better way...that's an option not many of us have within reason.

If the surfaces are not flat, they will leak, instead of a straight edge, I use a sanding block and medium grit wet sand the deck and base of the head.

[nitrousbaby]

yeah Ill try that first thanks I ll let you guys know what I find
