I have a 1996 Polaris Ultra 680 SP that we cracked a head on last year. All the antifreeze just came pouring out the exhaust. I have replaced all of the heads, and all the upper gaskets, it runs great, sits there and purrs, starts first pull, but the thing is just steaming up a cloud through the exhaust. Could the antifreeze just be burning out of the exhaust. It is an awful lot of steam, and gets worse once the engine has warmed up. I have all three cylinders off, inspected them, regasketed them, all looks good. Any ideas?
