Few things ive learned about POOGS

I still havent tried to resolve the POOGS issue with my bike. However there are a few things ive learned to do to help avoid the issue. Just thought I would share a few things for any new VN riders out there. Us thats been here awhile probably already know these.
1). POOGS will usually happen during the hotter days with the gas tank half full or less. So I try to keep the fuel level above that.

2). When the bike sits outside for most of the day (while at work) before I start the bike I open the gas cap for a few.

3). If im going down the road and the bike starts to have the POOGS issue, If I can do it safely I kill the engine right away and coast to a stop. This will make it easier to start instead of waiting for the engine to stall on its own. Open up the gas cap, remove the key and start the engine. When it starts shut the key off close the gas cap and be on my way.

Maybe someone else has a few ideas to help with the issue without doing the maintenance to prevent it.

I dont recommend this but ive even done this while moving, pulled in the clutch turned the bike off. opened the gas cap for a few. Closed the gas cap turned the ignition back on pop the clutch.

I think it be safer to just put a spare key in the gas cap so you can open it without stopping or turning off the motor.

Gas caps used to not have locks on them. That would have made this alot easier....

When I first got the bike this happened to me when I let the tank get below half and it had sat all night. What I wound up doing was pull over, kill the engine then engage the chock all the way and crank it over and it would slowly come back to life. Then I'd get myself the a gas station right away, fill up, and it wouldn't happen again.

I thought I had gone thru that in the past also, after cking my vent system came to the conclusion that I was a little slow switching to reserve. Now I always trip my odometer at fill up and change to reserve at about 120 miles or find a gas station.

04-3,200 miles bought July 2011 with 928 miles. Loaded with acessories to many to list here, see my albums for more details! I also make a custom tank bib specific for the 750 if anyone is interested, ck my albums for some pics.

It would be easier to fix the venting problem. If you have a CA model it is super easy, just pull off one hose. If you have a 49 state model, pull off the vent hose at the tank and blow through it to make sure it is open. If it is, then the vent is plugged somewhere between the cap and the hose fitting. Remove the screws on the back side of the cap, and remove the valve, put the screws. Remove the runner grommet at the bottom of the filler. There is a small protrusion on the cap that goes into that grommet. Now blow through the tank vent fitting (a piece of hose helps) and if air comes out through where the grommet was, then the tank should be venting ok. A "hissing" noise at the gas cap is a sure sign of venting problems. All gas tanks should be vented directly to the atmosphere, so they do not develop pressure of a vacuum inside.

I am a motorcyclist, NOT a biker.

I found the gasket in the gas cap to be the issue on my bike. It had mostly become unfastened. Thus no proper venting. I simply removed the old deteriorating gasket & no more isues. It's a big flat round gasket. I did also clean thew vent lines while I was at it.

Also, to note the proper explanation that was given years ago was "Phantom Out Of Gas Syndrome".

It really is easier & safer to fix it then to try to work around it.
