This is my first banshee and I rebuilt it. After I rebuilt it I would take it out and after awhile it would start puking coolent. I thought that it was the headgasket so I got a genuine yamaha headgasket and put copper spray on it and torqued them down and rechecked them. Today it was 50 degree's so I took the banshee out and all was good. I did a 1-6 gear pull for the first time ever and it puked up coolent again. I'm thinking the only thing that it could be is lean! I've been waiting to do a plug chop until the riding temperature was around were I would be doing most of my riding at. My banshee has T3 toomey's, boyseen reeds and a proflow filter and adaptor. I am running a 29.5 pilot and a 290 main jet in 679 feet elevation. I'm running Engine Ice coolent.
any suggestions or ideas??
