So I bought a new tank for my project bike which requires one of the honda flip-up type caps. I dont have one of these, so I would have to purchase one. But for certain reasons I have been thinking about replacing it with a completely different cap.

Specifically I was thinking of using a more modern, flush mounted, fuel lid.

Something like this, but it doesnt have to be. A more subtle, pop up type cap like the second picture, may be better:

Here is the kicker though, I need to find one that comes with its own metal base which can be welded to the tank as opposed to welding nuts to the inside of the tank. Granted, I could make this, but I would rather not.

Newton caps have a 3/4 circle inside the tank plate that takes the mounting bolts of the Aero cap assembly. You can get the caps from Dennis Kirk, but you'll have to make the 3/4 circle or try to get one from England. RR

Those are great, I am looking into those pieces right now. I am going to assume they are rather expensive. I am currently trying to figure out what actually comes in each kit.

I think either the Aero 200 or the similar 'Zero' range unit, which has a key.

They say that unit comes with a weld in neck, but I havent been able to find good pictures yet.

I just don't know why you'd want an airplane style filler cap on a Honda motorcycle.

That said, Carpy makes this one:

Joker Machine sells these (raw or anodized black):

I like flush mount. However, the ones you posted are very nice, and I imagine cost a lot less than a Newton.

They have some nice stuff, and their prices arent too bad either:

I dont really get how that first one is meant to be mounted though.

This part gets welded onto your tank:

754 · « **Reply #8 on:** March 28, 2011, 09:18:50 AM »

I saw the lower one, it was very clean and flush, and the cap goes in 4 ways. It was on a very slick v-twin that is getting ready for Bonneville.

I think the split mount one is for getting inside the tank, if the tank is already built.

q2418130103p · « **Reply #9 on:** March 28, 2011, 10:46:42 AM »

Thats what I was thinking two. I think the second unit needs to be welded from the inside, which I cant do, but the first unit (plit ring design) is what I need. Does anyone know why the ring is split? I am guessing you are supposed to cut a hole which is slightly smaller in diamter than the ring is, so you need it split in order to get it inside the tank.

Silverback · « **Reply #10 on:** March 28, 2011, 10:56:26 AM »

Yep, the split ring is a "no-weld" version. The gasket goes in between the top part and the tank and is clamped in place. The split pieces go inside the tank. Tricky to install, but a good no-weld solution. I was looking for a weld-in flip top myself, but may go with aircraft style posted, or cut one out of a Honda tank.

I like the look of the Carpy piece, but it requires a flat surface.

q2418130103p · « **Reply #11 on:** March 28, 2011, 11:22:42 AM »

Well I would like a weld-in, as long as it can be welded from the top. But A bolt on solution is nice and simple... But with the bolt-on you would need a very flat surface, and with the weld-in you could get creative with the weld in order to get it in a slightly rounded surface.

Also, I assume vented is required, as opposed to non-vented. Correct?

lol, nice. That happens all too often.

I am getting really tired of seeing "Made Exclusively for..." or "A [blank] original", only to find the same product online, from its Hong Kong dealer, for 1/4 of the price.

q2418130103p · « **Reply #15 on:** April 05, 2011, 03:27:45 PM »

Do I need a vented or non-vented cap.

I assume vented, since I dont know of any other vent for the tank...

My 1988 Honda HawkGT has a flush filler cap. Not quite a 70s part, but it does make a nice surface for a tank bag.

q2418130103p · « **Reply #22 on:** April 06, 2011, 07:42:56 AM »

I like them because they are clean. The tank I am using is already hugely tall, so another 1.25" off the top of the tank is really high.

Plus there is some putty work I'd like to fix near the current bung, which would require a lot of work anyway.

I have nearly finished deciding on the 2-1/4" bolt on, vented, non-locking, setup from custom cycle engineering. Currently I am just debating on whether the top of the tank is flat enough to mount the 3-3/4" outer ring.

Ha ha! I like what is says on his website. "OK, many people have asked about my Cool gas cap, so I thought about it and have now made it available for your very own CAFE RACER creation."
Glad that "he" has made it available for all of us. He is so gracious!

They are a period accessory, though I think those are reproductions. Anyway, consensus is they are not very accurate, finish doesn't hold up well, the lens cracks and yellows, the weight bangs around in the tank to where you can hear it. Etc. You asked.

PS: Not from personal experience, just what I've read. YMMV OCICBW

If I were installing the bolt in version, I would;
Cut a piece of 3/8 in or 5/16 steel or aluminum the width of the hole in tank x the diameter of the bolt flange, drill and tap to 3/8 NFor bigger. Now make a top piece same width or wider, dont need to round ends, but put thru hole in the middle for bolt.
Slip in rounded tapped piece, inside tank (you may need to hold it with a piece of tape or string) then put top piece on, insert bolt and tighten.. then slack off bolt and turn and repeat. It should? flatten the top area where the flange sits. do it gently..

That is almost exactly what I was planning to do, I think.

The top of my tank is fairly flat, but will probably require some gentle love.

My fear with this plan is that it could distort the surrounding area.

I was also thinking about taking a dolly, griding a ridge in it, and using that with a hammer to make a recessed ridge for the flange to fit into. I dont think I described that very well... I am going to talk it over with my father, he is far better at that sort of thing than I am.

There are bunch of cool and cheap billet caps for modern sport bikes on ebay now. Like this one...

Find a beat up tank where the cap area is salvageable for next to nothing, and then find the cap to match.

q2418130103p · « **Reply #28 on:** April 07, 2011, 08:37:11 AM »

Good thinking, I should go visit the scrap yard first.

Are they usually bolt on?

So I got a cap from custom cycle engineering for $165.

It came in packaging with there name on it.

On the bottom of the cap it says Newton Equipment. Turns out this is the same unit as the Aero 300 from Newton. Except when it is branded from newton is costs $300!!
