Bike only runs without gas line attached
I'm hoping one of you KLR gurus can help with this one. Here is the story so far...
I was riding today on a short trip back from my parents. It was hot (over 90) and I had been riding about 3 miles. I was at a stoplight, and the bike just died. Just like I had shut it off. I tried numerous times to restart but it just kept turning over.
At first I thought it had overheated, but the temp gauge didn't show that. After pushing it into a parking lot under a tree, I waited awhile and tried starting it again. No dice. It was almost as if it was either getting no spark or the gas was bad. I had never had a problem with the bike up to this point. It's a 2003 and I've had it about 3 months.
After getting it towed home, I came to the conclusion that it must be the gas. I popped off the gas line hose from the value, connected another hose and preceeded to pump some gas into a gas can by turning the engine over. The gas came out fine. No blockage from the tank.
As I was doing this, wonder of wonders, the bike started without the gas line attached! It sat there idling fine. I revved it a few times and all seemed fine. Just for kicks, I decided to burn out all the fuel from the line, and then reattach the hose to the tank. This took about 3-4 minutes.
I did that, turned on the gas, and tried to start it. No start! Just turning over and over. So what did I do? I closed the valve, popped off the hose and turned it over again... it starts! It runs until the gas line is empty.
I apparently have a bike that only seems to run without the gas line attached.
Any ideas out there???
Thanks in advance.
