Gas tank overflow!
I have a Fat Bob split tank setup.
The trouble I am having is when I need to fill with gas. I fill the right tank and never open the left tank. But for some reason the left tank overflows every time. Gas begins seeping out of left gas cap rim. Not just a little, but a lot.
If I level the bike and look in both tanks, the left tank is always a touch higher and not level. Of course when I lean it back on the stand, gravity takes over and the angle of the bike forces gas to over flow out left cap.
If I siphon gas from left tank while bike is off stand and level, the left tank bubbles and seems to vacuum suck gas into the left tank. I siphoned gas about 2 liters from left tank to a point where I could put it in the stand and it not leak.
It appears both caps are vented. This might be part of the problem.
