    Just finished my HF bike build. The only problem is gas leak!!! Seems like there is some sort of back pressure to the tank and the gas is spilling out from under the cap?? Tried two different caps even drilled a hole in one and tried that, still leaks!! Any reason for this. Could use some help any body.

    I have the same problem. Easiest relief: don't fill tank to neck. Allow some room between the cap and the fuel level.

    Tanks not full. I didn't put alot in since it was first time firing it up. Will this problem continue?
