So I got this bike that had a rusted out tank, I bought a tank on ebay that didnt have a cap, I moved the cap from my tank to the new (used) tank. I am concerned that the cap may have a leak so I keep the bike covered and I have a piece of leather that flaps over the cap just in case.

I want to replace the cap with maybe a keyless aftermarket cap. Any one use a specific one? I found some on ebay and some through google, not looking to spend more then 50 bucks really unless there is a reason to lol

post some pics or what you might suggest?

Thanks!

Edit** Here is the one I found on ebay... http://cgi.ebay.com/ebaymotors/Honda...-/300330576007
