Hello all, I bought this bike knowing that the cam chain needed to be replaced. I replaced the cam chain and 2 intake valves that got bent with the timing out. I also adjusted valve clearances and cleaned the carb. Spark plug is ok I think I'll replace it too just in case. My problem is that it will start with the choke but shuts off when I push the choke back in. From what I read the pilot jet needs to be replaced. I'm planning on doing that tomorrow. One difference I have is, after it shuts off I cannot restart it is this problem related to the pilot jet or something else? Thanks for you help!
