Man this shit sucks. Had a click before I went big bore with thunderstorm heads and flat top pistons from another bike I had. Just changed all 4 lifters, pushrods, and rockers tonight with know good ones. Still have a serious tick when my bike gets hot. I don't wanna run the bike anymore. Don't wanna fuck these heads/valves up. Any suggestions?
