Hey all, new to the forum but I have issues with it overheating, my boy was riding it with a bunch of "engineers" from Polaris and the t in the rad hose broke so they pieced it back together and dumped ice water in it when it was still at 250 degrees, (have a aftermarket temp gauge mounted on the fender) well I took it apart and put a new head gasket in it now it doesn’t blow anti freeze out the overflow resivor. It gets to 250 degrees yet but only boils over if I open the rad cap just a little. New cap and the thermostat checked out good. Also when running down the road it sounds like it’s shifting into a different gear? If I let it sit and idle it gets to like 220 the fan kicks in and drops to 160ish. Only when going down the road does it get to the 250 mark? What would cause this? Thanks for any and all help. Bob
