My gas cap leaks when tank is tipped on side? I Looked at the locking gas cap. I don't see anything obviously wrong with it? I would think it is not supposed to leak if the bike is dropped ? But it would leak if you tip it over? This bike is a California model I don't know if that has anything to do with it or not? Do they all leak if tipped over or is something wrong with my bike? Could this start a fire? I don't see anything in the service manual about this?

Using the side or centerstand will prevent this... :)) . Pretty sure they all will leak a bit if tipped .

Perhaps someone did as I had done to my 2005, removed the vent check valve in the cap. Never had an issue with it leaking even though I always filled it to the top of the neck (and then drove it home or somewhere) but then I never had it on its side either. It did solve the irritating "whistle" from the cap as temperature changed/increased.

If gas can leak out, could water leak in? If you wash the bike or if you get caught in the rain?

It should not leak. And Yes, water can get in if its a leaker...
If the tank is hot, and pressurized, and you spray cold water directly on top by the filler cap, or if you have a torrential rain when the tank was hot, it will suck water from the "recess" that surrounds the cap seal, when closed, thru the venting hole. That vent can be seen a a small nipple under the cap, that seals against the closed cap when shut, should be a seal there.

There is also a drain for that area, that attaches to the overf,ow hose, that runs down and back, and ter.knates at the rear by the axle... make sure that pathway is clear by blowing it out wjth pressjrized air, from the top hole in the recess..yo may have to remove the gascap bezel to actually see it, and when you do, when you reattach the bezel, leave out that single screw that lives under there, that prevents the cap assembly from being removed.. its a pre emtive strike, s you can remove a corroded and stuck fuel cap in the future, by simply remving the external screws on the bezel.
