I had a similar problem, but it was running out of fuel! I found the fuel tap was in the off position:banghead and it was only being fed by one side of the tank. fixed that and it's all good!I'm having some issues with bogging and stalling.
I have a new fuel tank and new petcock but nothing else has changed.
The bike will start to bog down while riding and then sputter to a stop. It will restart after it sits for several minutes and then be fine for another few miles, then starts all over again.
I checked my carb vent lines and found a couple that had been helf melted by the exhaust. I replaced them thinking I had found the issue, but it's still flooding out on me.
Any ideas on what to check next?
