Hey guys so I've been having an issue with my 00 Gs500e. It seems to occur when I'm at around half a tank of gas or so. I'll be riding along (the most recent time I was in 3rd gear), and it will start choking out. It wont start right back up after it cuts out either. I have to turn the choke on and give it some gas for it to start.

Tonight I was able to get it started and to a gas station to put some more in. It seems to run fine after the tank has been filled up.  Any ideas on where to start?

Have you tried turning the fuel selector to reserve when this happens?

Hi Geon,

The fuel level in the GS can be very deceiving...! If ya peek in the tank, it looks like there is plenty but really it could be right at the time to switch to reserve (or fill up).

How are you judging that you are at half a tank? Are ya going by miles or just looking down in?

Let us know what happens if this occurs again and ya try switching to reserve 

Thank you for the replies. Yeah, the first time it happened a few weeks ago I switched it to reserve, and it seemed to help. However I was only able to put about 1.5-2ish gallons of gas back in so I just assumed it was around half filled still.

If there is some kind of obstruction in the path between the tank and the carbs that might allow gas to flow when there is enough gas in the tank to push gas past the obstruction.

If you have an in-line fuel filter try removing that.  Check your fuel lines for kinks.  Past that I'm not sure, maybe look inside the tank at the petcock filter and see if it is clogged.

If the obstruction is inside the frame mounted petcock then running it on Prime might help.
