Stalling problem

bluesman · 07-25-2010, 07:55 AM

Noticed lately that when I'm coming to a stop and decelerating, mostly with the clutch in and using the brakes the bike (06 Nomad) is stalling. Doesn't happen all the time but did it frequently yesterday. Fuel is good, intake was cleaned a few weeks ago - any thoughts - possible idle speed to low? Other than that it runs like a top.
Thanks for your thoughts,

Might just be your idle speed is too low. If your weather is like mine in NH USA it is overly hot and dam muggy. Not much real air. So sure bump up idle 50/100 rpm and try that.

Is this all stock?

mine is doing the same thing and I think it's an idle thing as well. just have not bumped it up yet.

In Michigan it may be weather related too. The sencors should compensate in therory, but the real world and theory are not always the same things.

When jets are having a bad time getting off the ground, we all suffer some rpm loss.

Dying at an idle is also a sign that your throttle body needs cleaning as well. Check out the tech boards where it explains how to do it.

My 06 did it a couple times on a 800 mile trip. Bumped up the idle a bit and hasn't done it again (300 miles).

redjay · 07-25-2010, 05:24 PM

I cleaned my throttle body yesterday, the idle revs went up quite a bit today.

cactusjack · 07-25-2010, 05:46 PM

My vote is the idle speed is set too low.

bluesman · 07-25-2010, 08:18 PM

I cleaned the throttle body last week and it bumped up the idle so I turned it down, maybe too much - I'll up it to say 900 (I've got a tach) and see if that cures it. Other than that it runs great.
Thanks for the suggestions

Sorry forgot to mention that it idles fine, a lot of times I have to satart it twice as the first time it won't stay running but always does when I restart the second time. The dying problem only occurs when I'm decelerating with the clutch in and I let the idle go down. But I'll up the idle anyway.
Mac, I've got Vance & Hines baggers with stock air cleaner, may sound stupid but I don't know if I have a fuel processor. Bought the bike used and never asked. How or where would I look to see if one is installed.

Check under the seat or behind the left side cover. Those locations are the only places that would offer enough room for the controler. Most put them behind the left side cover. Easy to access it for tuning.

Dying when stopping or on deceleration is one of the symptoms of a low idle speed. It has nothing to do with how the bike idles, other than the idle speed itself.

Idle speed should be set to 950 +/- 50 rpm. 900 rpm +/- 50 is too low. You will have +/- 50 anyway you look at it, there is that much fluxuation as is.

Why are you using brakes when you should use engine braking, Don't be holdin' that clutch in coasting to a stop using brakes. You will add wear you don't to on the brakes.

As was stated look for a fuel modual under the seat or better behind the locking cover where it is typical a unit will be mounted. As far as I know most of these will have a rubber plug you can pry off with a finger nail real easy and then see led lights. Cobra does, TFI does, and PCIII does but the PCIII has nothing to remove to see them so far as i know.

Under that locking cover on a CDN bike there will be a velcro strap where most guys mount the fuel moduals. The strap is there to hold a California charcoal canister you don't have.

There are 2 main types of Cobra and TFI fuel moduals. One is Plug n' Play and the other type is solder on.

Both have smallish boxes a bit bigger than a Zippo lighter with wires coming out. Both so far as i know have bright marketing stickers in orange red colors.

If you don't have one you want one. If you have one you wouldn't want to run 91 octane or so called better.

If the engine pings on 87 octane there is a good bet you don't have any fuel modual at all.

If the bike has Plug and Play there will be piggy backed connectors on the injectors. But if there is a fuel modual soldered on there will not be piggy back connectors at the injectors.

Then wires would be soldered on the injector wires somewhere. I do that close to the ECU, but i can't guess where another man might do that.

A key thing to look for then would be any non-factory wires scotch locked or soldered to wires near the ECU.

If you find any scotch locks on the bike anywhere get rid of them post haste. They are all trash. A problem waiting to happen if they aren't already a problem.

The 2 wires off a 06 ecu added wires would be on if there is a solder on modual are gray and pink and gray and green. I see these incorrectly and understand the gray I see is a gray blue in reality or for all I know blue, but these 2 wires are the devils own work if you ask me to tell what colors they are.

So far I have installed 4 moduals, and each time i do I swear at the fool engineer who designed the battery hold down and the same about seeing the colors of these wires.

The good thing is any wires going to these wires will never be stock factory wires colors. No one can buy that color combination so far as i know and I know that much.

this is a pic of what the Cobra FI2000R would look like under the left side cover. It is the little silver thing toward the front, my the power outlet is under that cover also and is toward the middle of the photo

bluesman · 07-26-2010, 07:00 PM

So I took off the side cover and there is a box attached by velcro with a plug going into it (Blue,Red, Black &White wires) little bigger than a zippo lighter as Mac said but it has a little box in the top right corner says APMs and below are 6 tiny white switches numbered 1 to 6 with on written above the 1st and 2nd switch. Does anyone recognize this as a fuel processor or could it be the Alarm system.
Hey, I'm a musician what can I say.
