gas cap

Postby littlebeaver » Sat Jan 29, 2011 11:22 pm



I understand that the fuel cap should not make a swishing sound when you unlock it, this is creating a vacuum, I read that you are to drill a tiny hole in the top of the cap is that right, and I need to know if 1/16" is too large..? What are the aftermarket caps to, what type vehicle, does anyone know..where can I purchase one...?? :D Thank you in Advance..

It does sound like your tanks breather is blocked. You should not need to drill a hole in the filler cap, you should find the tanks breather hole and unblock it. Drilling a hole in the cap will fix the breathing problem but it's much better to fix it correctly (find the blocked tank breather) or if you recently changed the filler cap, get the correct one with a breather hole already in it.

You should have a hole about 0.7mm in diameter, I think that is about 1/32"

Took a quick look at Jake Wilson's web site and they carry the kit. Has the cap, gasket and the rubber retainer, OEM for $28.00.

I was impressed at the prives. They even carry the gasket set "A". Going to need that soon for the project bike.

A little bit of a swoosh sound is OK, the valve in the cap will always keep a tiny bit of vacuum in the tank. If it's to the point however where the engine is dying and there's a massive swoosh when you open the tank, it's time to do something about it.

Yes, I thought I would just make sure and drill a small hole in the top of the knob, I couldn't understand why the bike would just die for no reason like that...Made a believer out of me for sure.. I read all of this information here on this site a while ago and remembered it , many thanks.. :D

When I bought my wing from this kid, it always has had a weird idle. Starts fine, when idling or at a light it will build up or stay at around 2 grand. If I let the clutch out to bang it down a bit, it comes down, but then goes back up. Then as time went on, it would start dropping down so far that it would die. Then several times on 50 - 60 mile trips it would die at travel speed as if I'd turned the switch off. I'd always kept a spare set of plugs on hand because that seemed to have been the fix. One night at 3am, I was on the side of the road and someone finally stopped. He was a mechanic, I was replacing the plugs again. He said he'd follow me. About 8/10's of a mile same thing. It took a while for it to restart, we checked plugs again. Finally he mentioned unscrewing the gas cap, after listening to all my sypmtomology this was his big idea. I thought he was a crack pot.

Needless to say, I did. I fired her up, he again said he'd follow me. When I say follow me, I was in the lower section of Baltimore County, MD and he followed me well into York, PA. Almost 27 miles out of his way and on top of it....he was right. Amazing that someone would help that much and on top of it....the idea was so hair brained. Thought I'd share that with you folks.....

Isn't it funny how people show up to help you out at the oddest times, Walmart is over a few blocks and a man and his wife and baby had a flat and his jack had broken, he didn't speak good English, I speak a little Spanish, so I told him I would be right back, I ran home and got my floorjack and ran back, he had his tire fixed in no time, another time I was testing the bike and a guy broke down on 435 and I picked him up brought him home got a gas can with gas and road back and he fill it with what I had and was on his way, so I'd say that guy was telling you [BigRay] to pass it on, do something nice and kind to someone you don't know.. :D You never really understand any of this stuff until it happens to you..Someone's looking out for you..
