Thanks. I'll have to check the Honda dealer to see if I can get a gasket for the '95. My cap is fine and I disabled the lock but the gasket is cracked almost in two. It's not a listed OEM Yamaha part.
FWIW I discovered that some Honda caps fit the early TW tanks perfectly. This one came from my ATC Big Red, but odds are those from other Honda ATV's and street bikes may fit as well if you're having issues. Some may even fit the later tanks with the small diameter caps:
I can explain it to you, but I can't understand it for you.

Tirebiter - Did you have any luck finding a fuel cap gasket? Mine doesn't sound quiet as bad as yours but has seen better days on my '95. I was surprised that this isn't available as a separate part. The Honda ATC gaskets are available but wanted to confirm they work before buying one.

Personally I think it's kind of ridiculous the price they charge for these OEM caps.
The Yamaha part, 48Y-24602-00-00 costs 115 bucks at the dealer or about 80 bucks online from your parts guy de jour. Meanwhile people are selling them on ebay for 105 dollars (and people are buying them.)
I don't get why commonly replaced parts cost so much and yet other parts for the TW are reasonable. A cross reference list with part numbers so we can find them later would be great! The 'gas hole' is huge compared to any of my other street bikes, so I'm no good here in terms of telling you what fits.
I didn't like the look of the stock cap and didn't want it locking so I looked around and found the gas cap off a Yamaha FS1 fits perfectly. I bought a reproduction one off eBay for like $27. It's chrome with the Yamaha fork logo on top. Works great!
They exist, but I don't have any more. But FYI here are the two sizes for older and newer tanks.
They are vintage; I doubt they are being reproduced, but they may have been used over a far greater span of years than any of us realize. My shop guys salvaged a bunch from a throw away bin behind a Yamaha dealership a couple of decades ago.
Proudly display the tuning forks if you can get them. Tom

Same type of cap I bought that was reproduced. Got it from this guy on eBay: http://bit.ly/109Occ9 link probably won't work since I'm posting from my phone but look up 'Yamaha fs1 fuel cap' it comes up with ones with the forks and ones without. Seller is 'yambits' comes from over seas. They sell reproduction parts. I think they're also where I got my fs1 round headlight from for my bike.
