Unhappy Stator? or something else.....??

Ive got an 06 klr 650 with 5000 miles (2nd owner) bought a new battery and took it out for a ride and just died on me when i went to accelerate from a stoplight. Been seeming to cut out when my fan turns on. Almost think its my stator. Anyone got any ideas? Valves and doohickey done btw. Thanks!!! Oh btw it does have a vapor computer on it too.

Check connections such as battery cables, fuses then monitor voltage before jumping to any conclusions. Likely is a connection problem so that's the most productive direction and least costly to investigate. Any chance you didn't get the battery cables tightened? Or have a dirty connection?

It sounds like the issue is voltage related. Does it only do it when the engine is idling?

After checking connections & connections at fuses, try pulling the headlight fuse to see if that reduces the tendency to quit.

If you report battery voltage while running and have checked the other suggestions, post back results and we can see where to go from there.

May be voltage-related, but not, I think, battery voltage.

The battery voltage/charging circuitry and the ignition circuitry are totally separate on Generation 1 KLR650s.

The ignition (CDI, or capacitive discharge ignition) on pre-2008 KLR650s is powered entirely by the exciter coils of the stator; alternating current (vs. the direct current of the battery-charging circuitry).

So, whatever the problem is, don't think the battery voltage has anything to do with it--a Generation 1, in fact, will run without any battery at all.

That said, checking the connections between the exciter coils of the stator and the CDI, and between the pickup coil and the CDI appear to be sound maintenance. The ignition circuit is un-fused; the kill mechanisms (grounding the exciter coil leads by ignition switch or kill switch) might bear watching.

Here's a Generation 1 wiring diagram link:

Well its a brand new battery and the cables are tight and clean. I was going to check my battery today to see if its drained. It cuts out while im riding it not at an idle. I am going to check connections and use my ohmmeter/voltmeter.

Also when it seems to get hot that's when it starts to cut out on my and won't start again.

Reckon I didn't communicate clearly in my previous post, pokyIDAHO6ft4!

The condition of the BATTERY of your pre-2008 KLR650 has absolutely NOTHING to do with the running, or the dying, of your engine.

Because: The ignition of your bike is powered by alternating current from the exciter coils of you stator, not from the battery, nor from any 12-volt direct-current source.

I have spoken.

No. I'm saying, your battery, and the "AC part" of the other coils on your stator, are NOT the cause of your engine dying. Nor is the rectifier/regulator, unseen by the ignition circuitry.

If your engine runs at all, chances are the exciter coils are o.k. As I mentioned previously, you might check the wiring and connections, exciter coil to CDI, pickup coil to CDI, and the functioning of the exciter coil grounding terminals on the ignition switch and the kill switch. I think I provided a link to a wiring diagram, also.

Got a link on what the ohms or the watts to each part? Cdi, coil ect. Ill look for black spots on wires as.well.
Im guessing ill have to take off the seat and gas tank as well?
