Gas Cap Compatible

Discussion in '2-Stroke Engines' started by GoldenEagleChris, Nov 22, 2012.

  1. My gas tank leaks, i have the typical one you get when you buy these junk engine kits. I JB welded around the studs to anticipate leakage now i realize i need a better gas cap that ACTUALLY seals, cuz i notice mine leaking some gas.

    I am assuming it is a gasket issue, cuz the cap seals tight, I just don't know how little splashes of gas leak out.

    I have read that there are alternate gas caps that work, I looked on ebay, but all the real caps from motorcycles has threads for a twist/screw on style cap.

    My cap has no threads, just two little ear tabs that are spring loaded.

    Any links to compatable caps?

    JB Weld? Then you are over tightening the nuts. I used Silicon Sealer on the bottom of the tank to "glue" the tank to the cross-bar as well as 2 nuts per stud, the 2nd one acting as a lock-nut. The cap is supposed to "leak". This is to allow air to enter the tank to displace the fuel used. Mine does not leak out fuel because I put in only 1 litre (0.26Gal U.S.) thereby not over filling it. Do not lie the bike down on it's side, Use a side stand or prop it against a wall or fence,
