Runs out of gas with 1/2 tank
I'm new to the forums, but was hoping to get some much needed insight.
My 86 vulcan 750 runs perfectly fine until it uses about 1.6 gallons of gas (gauge at a little more than half). Then it acts like its out of gas. If I flip it to reserve, I can run it down to about 3/8 of a tank. Do I have the wrong pick up tubes on my petcock/tap? That's only explanation I can think of. I have not had the chance to drain the tank and investigate further.
I have also noticed that other people have RES, ON, and PRI on their petcocks, while I have RES, ON, and OFF on mine. Maybe the previous owner put in the wrong part.
It's not a huge problem to get gas every 90 miles, but it would be nice to have some range so I can go on a road trip.
What do all of you think? I appreciate any responses. Thanks!
