On my way home from work yesterday I started for run out of gas and switched to reserve. I went about another mile and I ran out of gas so it seemed. I leaned my bike over in its side to get any gas I had over to the petcock. It started ran for a short time and died. I had to do this two more times to get to a gas station. It wasn’t running very well it was only running on one cylinder. When I filled up it only took 2.5 gals to fill. I had a ½ gallon left in my tank. My tank holds 3.2 gals when full. Any thoughts on what’s going on? I should have pulled the gas line off to see if I had a good fuel flow before I filled up but it wasn’t possible. As soon as I filled up it ran fine again. I pulled the petcock out about a week ago and tested it on main and reserve and it worked as it should. I’m using a K&N 90 degree fuel filter installed by the carbs with a short line coming off the carbs and a longer fuel line to the tank. The only recent changes I switched to a different set of carbs that I cleaned up using Larry’s book. I also moved the fuel filter back down by the carbs. Before the filter was on the side of the carbs just on the outside of the frame. I’m at a loss. I think I should replace my petcock and move on. I’m just wondering if anyone else has had this problem. The only other change I converted my vacuum petcok to a standard.
