Let's start the adventure!

Hey guys,
With the encouragement of a fellow vulcaneer I'm keeping the bike and going to gain a little experience and confidence along the way. I'll start with an easy one. I went out yesterday to take a peek inside the gas tank. I put the key in, turned and almost broke the key. The gas tank would not budge. I played around with that for a little until I figured I'd break the key and start a whole new mess of things. Any ideas as to why my gas cap won't turn? Rusted shut? Any suggestions? I was hesitant on putting WD 40 in as I don't want to explode, die, mess up the bike, or a combination of the above. Any and all help is appreciated x's 10!

Try some PB Blaster - you can kinda zap it around the keyed entry and the cap (if I remember, the locking bracket is at 12 o'clock). You can also then GENTLY - with a rubber mallet and some soft cloth in-between - tap the cap a little just to loosen things. You may get a little Blaster in your tank, but, hey, it's combustable!

Also...well, you've put gas in the tank before, but I was gonna ask (only 'cause I've done it), do you have just the one key for your ignition, gas cap, and trunk?

On my bike the key will only open the cap if you have it in the correct way...It looks like it is the same on both sides, and it will go in both ways, but on my bike it will only turn the lock one way.
As for the PB Blaster, you have to be careful where you use that stuff because it will dissolve plastics......I would recommend going with the WD-40 or just some good old oil....Let it soak a bit, then try the key again.
Tapping it gently with a rubber mallet may giggle things inside a bit so it's worth a try.

I think it's that time of year! I had a crummy ride to work today (noted elsewhere), but came home, cinched up a few bolts, fixed the headlight (the bolts had fallen out of the bucket, so aside from the bulb going out, the bucket was just kinda hanging on there), and read some more about my new coolant "issue." I think I've bought three mechanical seals from Ayers now...the first one had an "unfortunate accidental encounter" with my sledgehammer ; the second one came apart in O's engine with whatever crud was floating around in there. And now I'm gonna have to get a new one for McK. I really hated the book "Zen and the Art o' Moto Maintenance," but I can certainly appreciate the overall sentiment about how much "tweaking" these things need!

BTW, scuba's right that PB Blaster is strong stuff - I don't recall any plastic parts on the gas cap itself (all the washers are rubber and everything else I can recall in there is aluminum), but if you're more comfortable with WD-40 or some other water displacement substance, by all means give that a try. Also, once you get the cap open, you can take it off the tank (two small screws there at the back - just don't lose those microscopic o-rings) and give it a thorough going-over (check the gaskets, make sure the locking mechanism is moving smoothly with whatever lubricant you use, etc.).

Sorry to hear about the troubles Cindy. :-( Hey, let me ask you this...how far down does your key go into the cap? I think I may have something stuck inside that bugger....which would be FANTASTIC! But I'm not sure... I'll mail you a cookie if you take a pic? :-D Or....maybe some Trader Joe's green tea with blueberry and pomegranate?

Woohoo! I'm going to take pics now (gotta get one of my coolant leak, too, so I can get some advice on that). Back in a flash (no pun intended!).

Here ya go, Mike. You'll see from the pics that the key doesn't go in very far (I was actually surprised...I was thinking it went in further than that). Also, "The lock part" pic shows the latching mechanism inside the cap that should move freely when you turn the key. I'm guessing that there's some crud built up in there that's making it stick. Not that there's crud in our gasoline supply or anything...

If your key doesn't work, you can get the cap off by punching out the pin at the hinge point. If all else fails you can take it to a locksmith to have it looked at.
