Hi guys. I posted up a few weeks ago that looked like my cam chain had jumped teeth while trying to start it. I just replaced the cam chain and tensioner, on start up it took a bit but fired up and ran long enough for me to get off the bike then stalled and will not fire again after kicking for a while it fuels up and backfires. I've double checked the timing marks which r spot on but still won't go. Feels like its got good comp. could it b something with the ecu?
