'01 KLR always dies when I close the throttle

About 30 minutes ago, my bike's engine died while I was waiting at a stoplight. I put it into neutral--which I usually have to do to start it up, anyway--and was able to get it going, but had to constantly hold the throttle open to keep the RPMs from dipping so low that the bike died. I called a friend who knows bikes pretty well, and he thinks the most likely culprit is an obstruction somewhere in the fuel line. What do you think, guys?

Hey Cabron. I like to do the simple and easy first. Because I'm simple and cheap. First thing I would try would be to drain the carburetor float bowl. It is a gathering place for moisture [water], and any other contaminants that might find their way into the fuel delivery system. I won't disagree that there may be a fuel restriction somewhere, however, in light of the information that the bike will run off of the pilot circuit [idle circuit], I doubt that is the issue. I am, however, frequently wrong. Clean out the float bowl first. Now start it and see.....

I know of many bikes and ATV's that run like crap on high alcohol content fuel, known as "ethanol". E10. My bikes all hate it. I shop for alcohol free gas or at least real low alcohol content. My KLR will quit running, act like it has water in the gas, won't idle, cut out at road speeds. Kill and until I drain the bowl and start fresh, won't start. If draining the bowl clears up the issue and it repeats itself, you may have a bad load of gas. Gas and water will separate. Usually in the float bowl.

Thanks; I'll give that a go. Nice signature, by the way.

I like to do the simple and easy first also. Try turning up the idle, should be >1200 rpm usually.

A mere jiggle of the "choke" (enricher) can kill a KLR at operating temperature (How do I know this? Long story!).

In Cabron's case, I agree with Spec; first, adjust the idle speed screw. vatrader's tips on draining the float bowl appears good maintenance practice.

Cabron, ever adjust your fuel screw (behind the tamper-resistant plug in the front bottom of your carb)? Might need to open it up a bit; you might need a tad fuel-richer air/fuel ratio at idle. 1.75 turns out from a soft bottom's a good starting point for a stock engine.

A couple east things to check:
1 Air filter
2 fuel filter
3 clean the battery connections

There are a lot of things that "can" cause issues so might wanna let us know, milage, pre or post 08, has the bike studdered or stalled before and the weather conditions when it happened. If you have a dry and clear bottle or glass you might try pulling the fuel tube and pouring some in the container to see if water settles out.

Disagree with inadequate battery connections as a possible cause of the problem, Buildit: Ignition and battery circuitry are totally separate on an '01 (thread title indicates model year).

'07 and earlier KLR CDI's (capacitive discharge ignitions) are powered entirely by alternating current from exciter coils of their alternators, not from battery voltage, AFAIK.

'08's and later KLR's have no CDI's; their inductive discharge ignition systems are powered from their battery circuits.

See the obvious escapes me sometimes. I'm just suggesting things the owner might not have thought of. Like checking the spark plug boot to see if it is arking causing a loss of power?

Good maintenance/trouble-shooting approach, as is checking battery terminals. Also, the GROUND connection (i.e., battery negative terminal to frame) may be critical; perhaps important to ALL model year KLR's.
