Stalled out and would not restart on the way to work this AM. Pretty much pushed a mile uphill back to the garage. Getting plenty of ignition, and have plenty of gas in the tank. All connecting points seem to be in order. Using a Pingel and an aftermarket inline fuel filter. My guess is something is plugging the fuel line. I'll check it when I get home this afternoon. Any other suggestions? Thanks in advance....

After cranking, pull plugs to see if fuel is getting to them. Then, lay plugs on engine head (grounding the plug) and crank engine, checking for spark. If you got fuel, air, and spark, something should happen, even if it isn't right, something should happen.

Did you loosen the gas cap? Might be a pinched vent line...

Tried the easiest thing first, loosened the cap, fired right up. Wiggled the vent hose around a bit for good measure. Hope that does the trick. Wish I'd thought of that before I shoved it all the way home.

Quite a few posts here about checking the end of the tube for blockage as well and some suggestions for cutting it at and angle. Take a good look...

and there is that little tip over valve in the
vent line, it can go bad or get stuck shut.

Save yourself some future grief and dry lubricate the tip-over valve. Get some dry graphite aerosol spray from your local automotive supplier. Remove the tip-over valve, spray the dry lube into both ends and shake the valve up and down.
Correctly re-install the valve. You can easily check the fuel tank venting system...remove the gas cap, put a length of approriate diameter hose on the metal vent tube that you see sticking up from the restrictor plate inside the tank. Now, suck on the tube like you would with a drinking straw. If you can easily draw air, then the system is fine. You don't have to suck too hard...if you do, you'll draw up the ball in the valve which will close it. Just blow, and the ball will reset itself.

Singring, that's a great tip about checking the vent tube going the other way. A length of tubing won't take up much room in the ol' tool pouch and could really save the day in the boonies.

Don't forget to check the secret fuel filter where the hose connects to the T between the carbs.

Done pulled that sucka out and installed fancy after-market job. Don't know if it's any better but it's sure easier to get to.

oldroadie, that tube/hose was one of the first things I put in my toolkit...I also carry a 2-foot length of 5/16" fuel line hose...never know when you might need to drain the fuel tank, or lend a buddy some gas..that's what I like about the gravity-feed fuel tanks...try that on a EFI Harley!!

Can't do that on most carbed Harleys either as they have vacuuum operated petcocks.
The Pingel on my HD has saved the day for my buddies more then once!
I had a similar problem as the OP on my bike and it turned out to be the tip over shutoff thingamajigger.
Course that was the last thing I checked.

Well shazaam, happened again. On the return leg of a 100 mile ride today I started sputtering and just conked out. Pulled off the gas cap to release the vacuum and all was good. For about 2 miles. Repeated as necessary about six times. When we got to my bud's house pulled the vent valve do-dad from the line. No rattling going on. Blew a bit of compressed air through the nipple and must have broken the ball loose. Was rattling freely. Made it home about 15 miles at 75 mph without another stall. Hope that does it for awhile. I'll try to find some dry graphite as suggested by singring.
Just curious...can you run safely without the vent valve?

That valve is in case you drop the bike. My 02 does not have this valve, it's just a tube to below the bike...

I did just that last night. Bike runs much better with gas getting to the carbs!

That valve doesn't do anything useful unless you dump the bike. Something to be careful about too, if you overfill the tank, gas runs down the vent line and makes the valve close.
