Weird gas situation

I have a 2008 with 7500 miles on it and have run out of gas (need to switch to reserve) after I've used about 2 1/2 gallons. When I refill, the tank is almost totally full and I've been getting around 50 mpg. As the tank supposedly holds over 5 gallons this is a real mystery to me. I bought it used and the guy told me it was running a bit rich but that doesn't account for the missing tank capacity. Maybe he changed out the tank but it seems stock, any ideas anyone?

The fuel pick up for the main fuel position is actually quite long. Reserve is much shorter. What you are experiencing sounds normal. Run it out of fuel in reserve and then see how much it takes.
I can get about 300 miles on a tank. I watch the odometer more than the fuel switch. At 250 miles, no matter where the fuel petcock is I'm looking for fuel.

OK thanks, I thought the reserve was really small, 1/2 a gallon or so.

That happened to me once after almost laying the bike down on its right side. When I filled up it only took 3 gallons. I figured the fuel went to the right side of the tank. Try laying her over on it's left side to move the fuel around. Reserve is only .5gal.

Leftside Tip: some of the gas stays on the rightside of the tank and you have to tip the KLR to its leftside to move the gas to the petcock.

I have had to do this twice before paddling into a gas station.

Not all gas tanks are the same. Learn yours and take heed.

We also had to do this in nowhere Utah (on a Sunday). Luckily we found a very noce couple that gave us gasoline out of their garage. They did not want any money but we left $20 in the front seat of their Jeep. We were 35 miles from the next gasoline.

Stock petcock looks like this:




Notice how much longer the main pickup is compared to the reserve. I actually cut about two inches out of mine to bring the two closer together. Now when I switch to reserve I'm really on reserve and looking for fuel.

Good pics, nice find. I've heard of people shortening the tall tube.
I think I'll be doing the same before a roadtrip. Also, the "extra reserve" trick
is famous on KLR's. Gently tilt the bike all the way down to the ground on the
left side for another 25 miles after reserve craps out and leaves ya stranded.

I had a bike that the main fuel pickup tube fell out so I was on reserve all the time. It was a dirt bike so there was no speedometer to know how many miles I had on a tank. It ran out one day and I had no reserve. I had to walk 5 miles back to my pick up.

That is something to think about if it seems like you are getting a lot of miles on your main switch.
