Ca. Gas Tank Issues-Need Help

5451 Views 12 Replies 8 Participants Last post by  qwerty
Hello guys,

I seem to have an issue with my gas tank, and I am only going to assume that it is my tank.

It is a California bike and has the odd vent type deal in the tank,(excuse my ignorance to what it is), some type of overflow or vapor catch system? Anyways, when I purchased the bike used, the tank was not overly rusty inside, but I did what I could to clean it out.

Installed a new Petcock, inline filter, new lines and fully cleaned the carb.

The bike runs great.....Until I get down to about a half a tank of gas, then it acts starved for fuel. This has only happened twice, and maybe it is coincidence, but when I top off the tank it runs fine until half a tank again.

Is there a dirt/rust issue that I did not handle with that vent/vapor/overflow deal in the tank? Or has this happened to anyone else? Filter is clean, Petcock screens are clean, I am just baffled.

Of course my next option is the Clarke TW tank, and then I have rust no more, my only concern is, will my bike be street legal with that tank?

Thanks in advance.

How does it run when you turn the petcock lever to reserve? I know when installing the fuel filter on mine, space was tight. Take another look at your filter install, does it require fuel to 'run uphill' at all before it drops into the carb? Good luck. Gerry
