timing is bang on and i did adjust the cam chain, but the bike did this to me once before but went away as quit as it came this time its here to stay. when the bike is running you can hear the carb pistons pumping then the rpm's go up then it drops back down and starts to back fire when it 's running about 2000 rpms??
