jetting? air leak? need some input please?

My banshee keeps shooting coolant out the overflow. Only when im in WOT getting on it hard. still has bottle on it. 310 mains 27.5s needle on 4th clip and 1400 ft elevation. stock except for Toomey T'5s. and bored 20 over. runs bomb. starts first kick almost every time. just seems to get hot at WOT. I think its still a little lean on the mains but not sure. any input would help thanks.

I wouldn't think that a lean condition would cause your coolant to overflow though, there could be air getting into the coolant system somehow, but if you think it's the jetting do a plug chop and find out.

Thanks for the input . The coolant doesnt even feel that hot at all when it shoots out. I think the radiator cap seal is torn. Ill check that out. Anyone else got any ideas also?

If your rad cap is screwed up, that will cause the problems you describe. Lean jetting will not cause coolant to squirt out just at WOT. If your coolant temp is not high, either the rad cap or head gasket is suspect.
