So im searching through ebay looking to get a gas cap for the tank i purchased. Using it for a track bike and put all my stock bits in hiding. I figured any gas cap is fine, but then i remembered the stock cap has that nice little pressure relief in it. Will a gas cap without that be fine? Or could the bike run like crap? They basically have 3 types on ebay, none of which has the pressure relief. Just wanted to see if it would be fine without it, i dont need the bike running like crap or stalling going around the track.

These are the 3 on ebay that ive found. Any suggestions?

Someone here has replaced there gas cap, im sure of it...

You can use either one but the Sling Shot Racing are the ones I am familiar with. They work fine and you won't have any issues.

If you run an UNvented cap the bike will run like $h!t.

Not a single problem, highly recommend!

why not just get a used OEM one for much cheaper?

I have 2nd link one on 3 tanks with no issues.

OEM requires the key to unlock. this is for a seperate tank for the track. Thanks guys, ill more than likely get the slighshot one and maybe get their adjustable fork caps as well
