I bought one of those little vent hoses with the anodized fitting for the gas cap(06yzf450). I opened the package, stuck it in some hot water to slip over the little nipple. It went right on & I didnt ride for a week so it dried up nice & tight. Well I went riding & after a few laps on the mx track, I noticed a lot of gas was coming out of it.I don't know if it has something to do with venting the tank or was it just splashing up & coming out because it wasn't sealed good? Any suggestions? I see a lot of people running these things, so I figured they must not have any problems. The only reason I bought it was to keep from running the stock one into the steering head nut.
