joeypecora Posted July 27, 2014 Hi guys, I was riding at the track yesterday and after about 2 hours of riding I noticed coolant coming out of the overflow tube, and only the overflow tube. I let the bike cool down, dumped some water in there, took another lap, and there was nothing above the fins in the radiator when I checked again. My oil is fairly milky, but it has always been that way. I was thinking it was a seal around the impeller shaft. Am I correct or is it a head gasket? Thanks!

tylerb137 My Rides (2) Posted July 29, 2014 For water to get into the motor through the impeller shaft BOTH seals would have to be bad, chances of that happening are very slim. Also you'd get coolant and oil coming from the weep hole under the pump. If water is getting in the oil you've got a bad gasket somewhere. head gasket, base gasket.

joeypecora Posted July 29, 2014 I have great compression so it wouldn't be a head gasket, how can I tell if it is the base gasket? Share this post Link to post Share on other sites
mxracermx My Ride Posted July 29, 2014 I have great compression so it wouldn't be a head gasket, how can I tell if it is the base gasket? it's kind of pointless which gasket seeing how you need to pull the head. You'll see then. At that point I would think about a piston Share this post Link to post Share on other sites
Shawn250 Posted July 31, 2014 Sounds like head gasket leak Share this post Link to post Share on other sites
