I haven't even had my 08 FJR for three weeks. It's only got 11000+ miles on it. It runs like **** :angry2: . Today, I rode probably 150 miles and was about 15 to 20 miles from home and the bike died as I was accelerating out of a small town. I started to pull over and suddenly it caught and I drove on. It got progressively worse from there. For about the last 10 miles the yellow engine was on and I barely managed to get it home since it wasn't running on all cylinders. I notice where the display is supposed to show miles it reads 33. I suppose that is an error code.

The day before I did the Barbarian jumper mod and I changed all the CO settings from 10 to 17. Any ideas on what I should do beside trading it in on a Gen 1? I've rebuilt engines before but this electrical stuff always tries my patience.

I would try to undo whatever you did. IMO this bike (mines an '08 with 24K) runs fantastic as a stock set up.

Hopefully you get it resolved soon. I tried to get info on code 33, but I believe you need a seperate manual for OBD troubleshooting codes. Someone will chime in and get you fixed up.

John,

According to a GenI Code list (if it is the same for yours) says that Code#33 is the following:

Open Circuit in Primary Wire of Ignition Coil and could be caused by the following:

1-Open or Short in Wiring Harness

2-Malfunctioning Ignition Coil

3-Malfunction in ECU

4-Malfunction in a Component of Ignition Cutoff Circuit system

Hope this helps...

 
Sounds like the ECU wires are not seated correctly, I would return to the original settings and make sure the wires in the ECU plug are seated.

Bingo.

The pins in the ECU connector are held in place by that white "snap" in bar. It's very common to have pins other than the ones you move work loose, and then not properly seat when you snap in the connector.

Pull the connector out of the ECU, eyeball the pins in the holes, and I'm pretty sure you'll find one that's at a different depth than the others.

I checked everthing listed so far and moved the wire back to pre-Barbarian status and still no go.................

After looking under the tank and around the battery I gave up and decided I better have another look at the pins in the ECU connector and how they were located in relation to the sliding white snap in bar. What I thought looked ok previously didn't look quite perfect this time for one of the other wire pin connectors. I relocated the pin and snapped in the white bar which snapped more smoothly than previously. I thought ok! I turned on the ignition and the error code 33 was still there. Then I tried starting it and the error code cleared and the gas gauge started flashing. I then realized I had forgotten to hook up the two connectors to the underside of the tank. Once that was reconnected it started right up and idled smoothly.

Today I test rode for 160 miles and it ran perfect all the way :yahoo: . I'll have to say that Kaitsdad and Millsaps2 were right on. Thanks so much everybody for helping me out. I do have the wires set back to the original locations but left the CO settings at 17 instead of 10. It seems to run a wee bit better, but gas mileage is slightly lower.

 
They simply followed the old adage "look first where you were last". Rarely known to fail.
