When I originally posted this, I had not seen the post by a new member over on Campfire. He and I are acquainted, and we have inadvertantly posted about the same issue. (BTW, IMO, we still need a general tech forum that is not model specific).
So, several weeks back, he noticed a hissing sound emitting from the gas tank whenever he finished a ride and killed the engine.
Hearing it while visiting with him one day, I opened the tank after listening to the noise and the noise stopped.
Our first thought was that it was a suction in the tank, and that a vent hose was kinked or stopped up. We fiddled with the assorted vent hoses, but the problem has not stopped.
And now, he has noted a slight seepage of gas around the seal of the tank at the cap. I know less than nothing about the pressure valve setup of the tank cap, and would not want to hazard another guess on anything as volatile as the fuel system.
So ... what are the possibilities here? And what suggestions might lead to a fix? All feedback will be appreciated.
Thanks in advance.
