Stalling....

[clayton]

Ok...
My Nad is stalling....
It does not do it enuf to complain except today I guess it hit a nerve....
It does it more so after I pull the clutch in to for instance turn right if I am in a parking lot to look to the left....
Now and then it stalls if I "goose" it just before I let loose of the clutch to pull out of an intercection....
It is NOT me just stalling it, it flat stops running to the point to where I need to restart....
Personally I can live with an occasional stall however when it about makes me loose control I get a bit pissy....
1: Stalling is not a safe measure in traffic...
2: it sometimes can be embarrasing...especially around and in a Bike Nite...
Why is it stalling?
What can I do to help this not happen?
I have 14,500 miles on the Nad.
Plugs look good...
Air filter is clean...
I use on a constant basis...Sea Foam.
Help me out here...
Thanks

Is you idle speed fast enough, have you cleaned the throttle bodies lately, are you running a fuel processor?

[cactusjack]

Yep, clean the throttle body first, then adjust the idle, if necessary.

[AlabamaNomadRider]

Mine has one sympton that your bike has. When the clutch lever is pulled back and I goose it as you say it has just quit. I don't have any other problems just ever now and then when I am sitting still and the clutch lever is pulled and I rev it. It isn't something that has me real concerned. And yes I have cleaned the throttle body, installed new plugs and run Sea Foam through it on a regular basis.

IMO, idle is very lean with a stock bike, it's just not getting enough fuel. Mine did this untill I added a Cobra FI.

Seafoam in the gas is good, but not enough. You have to do a good thorough scrubbing with carb cleaner and a toothbrush on the butterflies and insides. Youll notice that your mileage improves and that youll have to turn your idle down.

My Nomad only dies ever so often. I have now had it one year and five months and was bought new. It has probably done it less than ten times in that time. It does this when I rev it while stopped at a light or stop sign. With the clutch in and I rev it it will sometimes just die. Restarts immediatley.

Have used Sea Foam in about every fourth tank. Installed new plugs recent. I do have the Cobra FI2000R installed since August 2009. If anything the idle is higher than it needs to be. I gave the throttle body a good cleaning about two months back.

It has had this problem since the bike was purchased. It isn't a new thing. I don't think it is something I need to worry about. Just wondering if anyone has a clue why the bike would just die when you rev the engine like that.

[clayton]

To answer earlier questions...
Yes I clean the throttle body about every 4000 miles or so.
Idel was as high as I could get the knob to turn and have even played around with different settings.
No fuel processor...yet. (no job = no fuel processor :( )
I will have some down time tomorrow since it is "suppose" to rain.
I will clean it out again with some fuel injector cleaner or carb cleaner (which I think I still have some left)
So the long and the short of it seems to be....get a Fuel Processor? and this MIGHT stop?
Thanks Guys

Fuel processor. Mine used to do the same thing before TFI install. Almost had me fall off in traffic once turning at a light. TFI makes shifting better too, especially between 1st and 2nd.
Stock bike is too lean.

[macmac]

Yeap, to lean and opening the throttle just kills it, because that just made it leaner than it was. The is a lag time for the demand and you get a puff of all air, with so little fuel there is nothing to burn.

ALL internal combustion engine require a bit of extra fuel to get a stationary object to become a moving object.

The first demand for fuel, means the fuel mix should me set at 13:1, which in use becomes 14:1, and in acelleration tends to become 17:1 leaning out.

The 1 is always fuel the other higher numbers are air we don't have to carry thankfully.

Now I don't KNOW what the fuel mix is, but i am dammned sure it ain't no 14:1.

There is 2 laws at work here which go against one another. The law of physics which says the mix should be in theory always 14:1, and the laws of silly man and the EPA which says we should starve engines to death to make them clean.

The EPA law is wrong and is not cleaner. It is just engine stress, wasted heat, over heat, kills oil faster, burns up engines with PING, is dangerous, and wastes fuel.

The stall is just a too lean to run condition.

In some attempt to create a picture, this is like taking a blue tip strike anywhere match, and grinding it up to fine dust and then making a little trail of powder spread out over say 3 inches. Then expecting the whole trail to light the same instant, when friction is applied to what little is left of the match head.

I ain't gonna happen.

Clay, et al I think this is a fairly common problem on the 07 and 08 Nomads. I know of several others with 07s or 08s just here in FL that have the problem.

At idle, if the throttle is cracked just slightly the motor falls on it's face. Sometime it will give a tiny "pop" that sounds like it fired back through the carburetor then dies and sometime they just die! Mine has done it since new.

This same problem was so common on the early 900's that Kaw issued a recall and replaced the ECMs on a group of the 900s. I don't think they did so willingly though and I don't know what caused them to deal with the problem on the 900s. I tried to get Kaw to deal with it when my bike was on warranty but their response was always that it was "not a problem know to affect the 1600 FI Nomad" and that they would "monitor reported drive-ability issues for those particular symptoms."

I have found that I can decrease the frequency of the problem's occurrence significantly by just keeping my idle at or above 1100RPM and that is what I do. AT 950 It happens a couple times a week and at 1100 it might be only one or two times a month.

But, although the FI controller did many good things I did not find that having a FI controller on my bike had any impact positive or negative on this problem.

[redjay]

To Trosco, the problem affects the 05's too.

[macmac]

And 06.....

[billmac]

Mine use to cough and die. Or die, without a cough. Very frustrating. It is hard for the bike to run when it is adjusted for the EPA instead of what is safe for you and good for the engine. Good luck on getting a TFI. That solved my problem for good.

[dabull]

ditto 05....
