Just got home, about 5 miles from the house, i get the bird chirping noise on light acceleration. Rear head gasket leaking right under the spark plug. just over 5k miles on this engine. so,question is, tear it down in frame, put just the rear head gasket on and get the rest of the riding season underway. or tear engine from frame, and do both head gaskets, and cylinder base gaskets. they seem to have seeped a little oil since day one. my experience tells me tear it all down. but the rider in me says get it on road as reasonable as can be and get riding. any recommendations for gaskts brand? i have used Jims in the past. May switch if the price is right and there is a better one out there. Brian. 91 EVO 80 inch in a Custom Softail.
