POOGS x 2 in two weeks

My baby's been riding so well for so long that I'm totally bummed over this. Twice now while riding on the highway I've had to pull over due to POOGS. The first one took about 10 minutes to re-start, following this procedure several times: opened the gas cap for a while, closed it back up and tried to re-start.

The second time it only took a minute to restart. First I followed the above procedure twice. Then I opened the gas cap, took the key out and re-started with the cap opened. Started right up! Had to shut back down to close the gas cap, and it re-started right up again. Rode home no problems.

Both times I was about 1/4 tank full with the petcock in reserve position. I usually ride in reserve position on the petcock to avoid sediment on the bottom of the tank, but I switch the petcock to normal for a while with each fill up just to keep some gas flowing through that pathway as well

Could my gas cap vent hole be clogged and can it be cleared easily?

I solved my Poogs problem once and for all. Take the gas cap apart, three screws. Inside you will see a little orange or maybe red flapper valve, on the bottom. Pull the little flapper valve out and throw it away. Have not had any trouble with poogs again. After doing this it stops the tank from forming a vacuum keeping the gas from flowing to the carbs. This was usually on hot days. This has caused no fuel leaks or problems, for over 5 yaers and for the last 10,000 miles. Just my two cents.

Thanks KM. Didn't even bother to look before I posted. Just wanted to vent cause I was so bummed. But the sticky is perfect and I'll be fixing the problem this weekend.

hi I did this too and no more problems. The only thing when filling up don't fill right to the top leave about a good inch or a little more and all is good. I check in to see if i could buy new parts for gas cap and around here you cant get them at all, you have to but the hole gas cap at a cost for me $ 130. So taking out the value is at no cost just a little time.

Removing the silicone valves from inside the gas cap does is not a guaranteed solution to POOGS. POOGS is caused by a blockage anywhere within the venting system; gas cap, vent tube in gas tank or vent line. So, even without the silicone valves some dirt/mud/bugs could plug up the vent tube, and POOGS would return.
