Fuel delay in transferring from ON to RES
Have noticed that when switching to RES on the fuel petcock I lose 1 of the cylinders for a brief period and several times lost power completely. The bike will eventually start back up after sitting a few minutes.
I also noticed that upon cold start only 1 of the 2 cylinders is firing during idle and corrects as the engine warms up or the throttle is opened
I pulled the petcock and the screens are clear and undamaged. The vaccuum diafram looks and seems to work, on the bench. Was thinking of pulling the carbs but don't think that will help and besides that seems to be a royal pain in the ass. I did not disassemble the lever side of the petcock but probably will to see if dirt clogged.
the bike has 24000 miles, the VH cruizers, been marbled, and KN filters but otherwise is stock.
