Title: Fuel Cap Upgrade
Post by digitaltrucker on 07/02/25 at 04:58:33

Here's my solution to the eternal problem of the lousy fuel caps on these things. I got one of these first.

The spud reasonably fits the hole in the tank. I secured it with JB WaterWeld putty, supposed to be gas resistant and suitable for tank repairs. It's the white stuff.

It cures quick and after it set overnight I painted a layer of regular JB Weld over the top. First trial it seems to do the trick, I guess I'll find out how well it holds up. So far no leaks and no seepage. I'll worry about making it pretty once I'm sure it will work. A dab of filler and a shot of paint should do the trick nicely.

The perfect solution for a problem that doesn't exist.

You mean the problem of fuel constantly seeping out around the stock fuel cap, even on a brand new machine? The problem of trying to shim up the gasket to help keep it sealed? The problem that replacement OEM gaskets aren't available, requiring one to either roll their own or try to track down a similar Honda part that might or might not be available?

To which of those "problems that don't exist" are you referring?

On a side note, I tested it out pretty thoroughly today. I did get a tiny bit of vent seepage when I deliberately fueled it more than normal (on the kickstand, filled to the bottom of the inner neck). Even so, it only seeped once right after fueling and getting the bike upright and was far less than I've ever seen before.

Bottom line; assuming I fill the tank like I normally do and the JB Weld claims that it's gas resistant aren't terribly inflated it's a success. One nice thing is that the gray JB Weld smoothed out somewhat as it cured which will make it easier to prettify it.
