1200 sportster not running on both cylinders. Rear doesnt seem to be getting fuel. Checked and replaced vacume lines. New plugs, plug wires, treated fuel in tank. Used carb cleaner and it helped a bit. Plug wire has fire to it. Not sure where to go from here.......Thanks!

Re: rear cylinder not getting gas?????
As both cylinders are fed by the same carb and manifold then it would point to a problem with the rear cylinder but a leak on the rear cylinder/manifold seal may result in a very weak mixture to that cylinder after that i would be doing a compression test

You pull the front plug wire and the engine flat out dies? As Jack said, a compression test is in order. |
