Last night I was happily on my way when right in the middle of traffic the engine huffed, puffed then died. I started it back up, it was a little hesitant to do so, and took off. Then it happened again, this time as it was huffing and puffing away I pulled into a residential street. I tried starting it up again, with little to no success.
I did notice that the engine sounded funny (when I would blip the throttle it "whirr" from around the primary chain area, maybe a little more toward the front).
Then I tapped the tank/frame to check for gas, and it turned out that indeed it was bone dry. Luckily there was a gas station a couple of blocks down. Filled it up and started right up.
On the other hand I am worried that the low fuel light won't go on again so I will be keeping a close watch on my fuel level. Also the noise from the engine is still there and it just does not sound right.

-So does anyone have an idea why the fuel light would go out? (could it be because its been raining lately, and I have been commuting in the rain? although I have done it may times before)

-The engine "whirring" (actually sounds like the whirr a semi makes [I think its the turbos]), what could be the cause of that?

The whir is probably the fuel pump. Just an FYI if you need to run for a while w/o the fuel light...

Mine usually comes on between 110 and 118 miles. Even if the fuel light doesn't come on, I would imagine that the circuit that kicks in the fuel miles meter will probably still work.

I will turn on the low fuel meter and keep an eye on that one... (thanks for the tip)
I am highly doubtful the whir is the fuel pump (I really wish it was). The whir is coming distinctly from the primary case area... And only when I blip the throttle or when I am decelerating.
If it would be helpful, I can try to record the sound and send it to anyone who is interested...

If that's the case it's most likely primary chain tension. It's not difficult to adjust at all... But it's very important to get it right. Too loose and it won't shift right, too tight and it could get VERY expensive...

It's easy to adjust though. Do you have a service manual? There is a cold and a hot setting. I usually use the cold setting and I make the adjustment no sooner than about four or more hours after a ride to make sure it's cold. Usually after it's been sitting in the garage for an entire night.

Sadly I do not have the service manual, could you please fill me in on the procedure. I really do hope that its simply the primary chain tension.
thank you very much,
Peter

bikoman, great thanks
Just a quick question, how different is the 2003 and 2004 as well as 9/12 in terms of the primary (if different at all)?
