Question Bike broke down... How to fix?

So I went on a ride this past weekend. Got caught up in some construction and was obviously having to drive slow in bad heat. The bike did not overheat but it died. It would not fire back up. I got it pulled over to the side of the road and waited a while, and eventually, while giving it a lot of gas, it finally fired back up. I check the bowls and they had fuel in them. Anybody have any clues of what happened and how I can prevent this from happening again. I used to run a lot of parades with this bike, and would have the same problem.

Could be whats known as POGS round here (Phantom Out Of Gas Syndrome)

If it happens again, try opening the gas cap to relieve pressure inside the tank and see if it starts back up right away. If that's it, you will likly need to clean out the tank and gas cap vents.

do a search on the forum for pogs and you should find all sorts of info and fix directions.

...thats my 2 cents worth.

......I'd rather wake up in the middle of nowhere then in any city on earth.

I think a new name needs to be given to this problem as I've seen it a lot on here. I had the problem too though mine would start after a few tries, and a back fire, that sometimes would draw random return fire depending on the neighborhood I was in. New starters and rebuilds of same, did no good.

You have a low battery ( or weak stator) and with the fan cycling on and off in the hot temperature the engine stopped because of low voltage. I also noticed in your sig that you are running speakers and a bright headlight. Seems you are overloading the system. Reduce your watt usage and get a good AGM battery. JMO

For those that didn't notice, he did the pickup coil mod and has a Westco AGM battery....
POOGS is a good guess. I too am concerned on how much power you are using...the battery doesn't charge well at idle speeds, do stop and go along with extra electrical drain could be part of the problem.

POGS was my first thought, that's why I checked the bowls (I opened the gas cap first). The stereo was off. My wife was the one riding it, and she tends to rev it up quite a bit when moving forward (she's a newer rider). Battery seemed to have plenty of juice, as from trying and trying we would have been drawing more and more juice, but the starter never slowed down the way they do when the voltage gets low. I've heard of the R and R relocation due to heat... Would that have anything to do with it? (I have not done this)

^quite possible. I noticed when stuck in traffic due to an accident, on a fairly hot day to start with, my charging voltage dropped to 12.8 volts....where normally it would be 13.8-14.5. Only thing that I could deduce was the R/R was getting hot...due to the heat from the engine and goats belly.

But you show you have V+H pipes, so I assume no goats belly?? But the R/R could still be the problem.
Again does sound like POOGS.. So I'd look into that first, check ALL your electrical connections and grounds, and if you do plan on being in slow moving parades, might not hurt to relocate the R/R.

I think you should install a voltmeter to visually moniter your charging voltage.

I think both mods are a good idea. I will have to do the research on them as I know I've seen post on here on how to do them. And you are correct, there is no goats belly anymore

Sound like it flooded to me.
