I posted this in the general Touring forum yesterday, but I think it might belong here instead:

I bought an '01 Road King Classic on Friday and trailered it home from the dealership. The test ride at the dealership went fine, but yesterday was my first chance for a longer ride. After about 30 minutes, I had to stop for a light. The engine started idling rough, then died. It would not restart until I cycled the ignition off and back on again. I decided to head home and had to stop twice more on the way. Both times I had to open the throttle a little bit to keep the engine running. When I got home I let it idle in the driveway and it died again. It seems to idle fine when cold, so I'm hoping the hot idle just needs an adjustment. However, I don't understand the need to cycle the ignition to get it to restart. I know that causes the fuel pump to repressurize on these fuel injected engines. Could I have a bad fuel pump? Any help would be greatly appreciated.

The dealership I bought it from is 2.5 hours away, so taking it back over there is not a great option. However, I'm going to call the salesperson tomorrow to see what she has to say about it.

 

I would check your Battery cables. I have seen bad connections cause all sorts of issues

 

Probably the Hot idle on the MM EFI needs to be adjusted.... Mine will do the same thing on occasions...it is a finiky piece of equipment. I never recycle the ignition switch when it dies, just start button and maybe a little throttle.....

 

Yep, I've found several posts on the subject now. One indicating that owners of a bike with the MM EFI should get familiar with the idle speed adjustment process. I've already got a service manual on order. There is also a sticky on one of these threads that details the adjustment process for both cold and hot idle. Unfortunately, no pictures, which is why I order the manual.

 

just about got to have the SM to take care of these babies.....

 

When my 01 Ultra does that, I take a/c off and clean the air bleeds inside the intake. They are at the 2 and 10 o'clock with MAP sensor cleaner. Stick nozzle in each hole and cycle on ignition, wait a few seconds and repeat til clean. I stick a rag inside, next to the butterflies, as it doesn't like to run right for a few minutes if it get into intake. 51000 miles so far with no problems.

 

I would be interested in knowing what you're using as MAP sensor cleaner. A quick Google search shows some people are using brake cleaner, some are using carb cleaner, and others recommend a low-residue cleaner such as electrical parts cleaner. There doesn't appear to be a product made specifically to clean MAP sensors.

 

. correction.....that would be MAF sensor,,,MASS AIR FLOW-- located in the air duct normally between the filter and TB>>looks like a little resistor....Available at most parts stores, Bumper TO Bumper/ autozone, O'Reily.......I usually use carb cleaner,,,they also make a spary cleaner for a Throttle Body. I've used that on my Trailblazer......

 

I buy it at NAPA. Says MAP sensor cleaner on the can.
