New 06 head/ss valves, new jug and piston, rejetted carb with JD kit, Boyesen quickstart, countless hours rechecking cam timing, valves, carb, even compression and cylinder leak down, even replaced ignition module with new Procom Rev Box last week, still same results. Cold starts with high effort and inconsistently, hot starts are almost impossible. Bump starts ok hot or cold, runs great once it's lit. When it does cold start with the kickstarter, it takes a jumping kick like an old cr500, but there doesn't seem to be alot of freeplay in the kickstarter gear. What am I doing wrong? Any input is appreciated.
