Do H.D. Sportster gas tanks, need some sort of ring around the hole, for the gas cap to grab onto?

Question

I just bought a yamaha xs650 bobber project, in which came with a Harley Davidson Style Sportster Gas tank, I'm not sure exactly if it is a true H.D. or if it is a Replica for custom motorcycles. Are most gas caps right handed turn, or left? and where can I find a semi basic one that would fit this, and will any H.D. Sportster Gas Cap work.

Answer 1

Don't know what you have but my Shadow has a locking one that just pops up when the key is turned. When you put it back on, it flips the key back straight and it is locked on. There is a seal on the CAP and a tab for locating the cap to the tank (orientation) so the lock cylinder will be up and down.

Answer 2

Righty tighty ..........I've never bought a tank that didnt have a cap, but I believe youll be hard pressed to find a cap that doesnt fit.....

Check your Local swap meet man............. search your location at this site............

Take your tank, make sure it fits, most vendors want to get rid of the parts, and make all sales final.......

Answer 3

Some HDs that had split tanks, FXSTC etc. had two caps one was vented and one wasn't. The vented one had right hand threads, the non-vented was left handed. That way your tank was always vented, you couldn't put the non-vented cap on the vented side of the tank.

gas cap is cheap and lo and behold a chevy gas cap fits old sporty tanks to.

Answer 5

Harley/custom tanks are either s***w-on (threaded),

or cam-lock (1/4 turn)

Answer 6

I'm almost positive there is supposed to be a black rubber ring either around the gas cap itself or the gastank whole. If you can find any serial numbers on your gas tank you can call any harley davidson shop and give them the part number and ask them to check on it. Any numbers off the tank will help.

on the newer peanut tanks the threads are on the inside, the older sporty tanks had a regular push down and twist cap, go to ebay motors to motorcycle parts American and punch in gas caps and see the differences.
