Bike wants to stall out?

Hello - I need to ask for some help with a problem that started last a few months ago. Whenever I get stuck in bumper traffic (stop & crawl traffic) and the bike is running hot (fan running / bike not over heating) the engine starts wanting to stall out and I have to give a little rev to keep her running.
I'm wondering if this could be the stator or battery. The battery (sealed) is a few years and I do run the bike year round. Any suggestions be most welcome. Thank you!

I was having similar issues with mine a few months back...when it stalls can you restart the bike?

Yes when she does stall out I can restart. It might take a few trys. Sort of gotten use to it now so I be lightly reving the bike more and letting off a little on the clutch when it feels like she's gonna stall. Of course this all while sitting stuck in traffic. While driving - no problems! I'm thinking about recharging my wet cell battery and run with that just to see if maybe the problem is my battery.

What is your idle set at?

Did you move your R/R?

When it is hot like that the bike is not happy sitting there, so really it is kinda expected to blip the throttle some while waiting for a light to change.

With the fan running and idling your not getting a good charge, so you can either keep the rpms up some with the throttle or reach down and set the idle up some.

I just open the throttle a crack till it is running smooth.

A few months ago I relocated the r/r with Bulldog's kit. Good thought about the idle speed. Will try that for sure. Thanks!

What most likely is happening is that while you sit at idle with the fan running you are putting a greater than normal load on the generating system. As the load increases due to the fan and now the battery trying to claim its share of the power, it puts a physical load on the engine because the generator is becoming harder to turn with the added load. This causes the rpm to drop which also causes the amount of current available to drop which ends up as a negative feedback loop. Unless you increase the RPM, the engine will stall.

Everything you say sounds right - I forgot to mention that I really feel the stall coming on when I am applying the brake and since that means the light comes on - more power demand on the stator. Thanks for the input!

All of the above is probably contributing to the problem however I had a similar situation and here's what it was. The manifolds that the carbs mount on feeding the cylinders seem to be rubber. I had an air leak between the carb and the engine. I seem to remember that it was the front cylinder. Whenever the bike warmed up I had eratic idle. After the clamp was tightened the bike ran normally.

If you suspect an electrical problem, I bought the Kuryakyn LED voltmeter (battery monitor) hooked it up between ground and one of the front marker lights. It will tell you how much voltage you're getting at all rpm so you will be able to see for sure. It's small and I mounted mine right above the Kawasaki right above the front of the tank. It's perfect.

Hey Gemguy,
Thanks for the input and I will check that out too. As for the LED voltmeter that is long overdue and will order one from Dennis Kirk. It will be nice to know see how much voltage I'm making from a stop to highway cruising.
Thanks!
