Gas cap air lock?

Hey everyone?

New here to wristtwisters! Very well organized board....reminds me of ADVrider at for the 919! Nice!

I have a new to me 2003 919......the gas cap keeps getting hard to open. I loosened the 3 bolts last night, reseated the cap....And it was openng and closing beautifully! Now today after a 40 miles commute it won't open without excessive force again.

Is there an air vent in the cap somewhere?

i have to insert the key, turn it till it puts pressure on the mechanism then push down on the cap then the key turns easily the rest of the way. maybe this will help?

If it's a venting problem, it should open and close easily after you do get it open following the initial struggle. Is this the case? Is it a stock cap? If not, some aftermarket caps apparently are not vented properly.

Mine has done that in the past. It is not air locked. Loosen up the bolts again and reposition it again a little further back.. Make sure to get them tight. Also, apply a small amount of lubricant (I hear graphite works best) to the hinge.

Press Any Key To Continue.

If you do some searching there is a post about adding washers to the front screws to fix the issue, I've noticed on my tank that when ever its about 95-100 degrees out I have trouble opening it and need to fix it

I had issues with my key sticking in the cap and refusing to come out. Replaced the cap with an ebay screw-off type. No problems so far, unless you count the black anodized finish not holding up to the sun. (It's sort of bronze now.) Actually heard it vent the other day. Left the bike outside in the heat while I was at work. When I got home and started to move it into the garage, I heard it vent a couple times. Never noticed it before, but probably because it's usually in the garage or else I'm starting it right up and the engine noise obscures the venting noise.

you overtightened the mounting screws i bet.

got a torque wrench?

if not, try loosening and retightening to a lower perceived value.
maybe carry the allen wrench in your pocket in case it seeps a little on the first couple rides.

also, i push down on the cover while i turn the key to remove pressure from the latching mechanism.

Thats good advice. I've had difficulty getting the gas cap open a couple of times, but never to the extent that I needed to really dig into the problem. Pushing down on the cap as I unlock it has done the trick so far....

Well, fire the engines! Spur this iron space-pony on!

Try swinging a chicken around your head counter clockwise while facing 34 degrees and hoping on one foot. I think that should do the trick. If not, call a plumber.

Never tried loosening the mounting screws. I just assumed they were factory spec. Might have worked. With the old cap, I would have no trouble inserting the key and opening the latch. But when I would close it, it didn't want to turn and release the key. Made me crazy a couple times when it was really stubborn. Anyway, now I'm used to the screw-on type, and I think I like it better than having to mess with the key every time I need to fill up.

Interesting, this problem coming up again. My 2007 with 8000 miles started getting a little hard to open for the last month. Decided to throw a spare allen wrench in the tool pouch just in case and sure enough, yesterday the cap wouldnt open. Removed the three screws and teased it off. As an old guy (57) I have learned to never never ever ever ever force a stubborn lock with a key. I am going to search on this as I remember there are some threads on this not uncomon problem.

Havn't had this issue yet, please keep us posted on what you find. I'll keep an allen in the tool kit just in case...

yeah --- you guys are right.....when it gets stuck....if you open it, it doesn't get easier to re-open, until you loosen all three allens. The problem seems to be mechanical.

If anyone finds the link to the Washer fix thing... post it up.

For the time being, I'll probably try digging up the torque wrench in the honda service manual and see if having the bolts looser will fix this. (not a bad idea to lube the hinge either....)

We talked about this last summer. I believe the alloy cap swells more then the rest of the metal opening. It happens like Jeef said when it's hot outside.
