I have a 1995 Tw200 that has a California fuel cap on a normal tank.(no rollover valve underneath)

I'm having fuel flow issues due to there not being a vent in my tank. Is there a way that I can make my gas cap vented, or are there any aftermarket replacements available? Any help would be greatly appreciated because pulling over on the highway, taking the key out, unlocking the cap, twisting it off, locking it back, and then starting again with cars whizzing by is no fun.

Cali bikes vent through the carb.

There's a tube inside the Cali tank which leads from just under the filler neck to the outside of the tank, then leads to the carb, so it doesn't need a vented cap.

If you put this cap on a 49-state bike it will have the same symptoms as a clogged vent.

He should take you up on your offer. Those metal caps are hard to come by and almost never clog.

Not backwards. Exactly the same, different route.

In your case you now have redundent venting, both through the filler neck vent and the cap.

The little fuel filters for weedwackers will keep the crud out of your vent line. Or you could simply cap the tank fitting since you're running a vented cap.
