My gas tank has a hissing sound after riding. When I open the cap pressure is released. I recently installed the DP cap can I have installed it incorrectly to not allow venting?
The only time I see pressure released from the tank is right after a spirited ride and I let the bike sit for awhile(few mins). When I am ready to get gas I just open the gas cap as soon as I stop and have not had an issue since.
