Over the past 4 months, my 06 Uly died 5 times while in moderate-heavy traffic. Cycle the kill and/or ignition switch and the lights go on, needles sweep and starter cranked strong, but the fuel pump didn't prime and the ignition was apparently cut out. Strangely, after 10 minutes, she would run fine for another month/1000 mi or so. Also, a few times when stopped (intentionally when warm) it wouldn't start up for about 10 minutes. Fan operation seemed to be working just fine. Never any current or historical error codes in ecmspy. Based on suggestions on BADWEB, I checked under the airbox to find that the woven cover of the Engine Temp (ET) Sensor wire was chafing against the top of the rear cyl head and wiring harnesses. The insulator didn't seem broken, but I think there may have been a short or maybe worn sensor. Probably my fault when I did the breather reroute about a year ago. Picked up Engine #P1278.K, which applies to all XBs and some prior tube frame models. It has a seemingly heavier duty insulation, some reflector-treated insulating split-loom tubing, and a new connector design that seems much better (though maybe unnecessarily so) than the old rubber-sealed bullet connector.

To start, you'll need to remove the airbox cover, filter, base, disconnect the intake air sensor plug, unbolt the dogbone-looking bar and swivel out of the way. Tools: -flashlight -1/2" (12.7 mm) deep socket with about 2" of one side cut off to allow for clearance of the sensor wire -socket wobble + extension -razorblade/needle-nose pliers/tweezer to remove old female connector There isn't a lot of room to work, so take your time. Careful to never bind or tug on the cable too hard as that could ruin this $80 part. Unplug the old wire bullet connector and pull up the rubber boot over the sensor. This was a little tricky: a pair of chopsticks and serrated steak knife worked for me. Work modified socket over sensor and unscrew about 3 turns. Replace with new, being careful not to bind/stress the new wire or cross-thread. Torque spec: 120-168 in-lbs. The rubber boot should be oriented with the flat side to the left of the bike. Carefully remove old female plug. It shares a harness with the O2 sensor plug and there was no spare length of wire on my bike. Cutting the wire wasn't an option. You'll have to slice off the rubber cap and uncrimp the old wire connector with fine pliers to save enough length for the new plug. You should study the new plug and get a good sense of the order and orientation of the 4 parts. The instructions that came with the part suck. Crimp it on and assemble the plug. Though it's a well-sealed plug, 2 dabs of dielectric grease wouldn't hurt. Carefully route the wire and mate the plugs. Reassemble and clean up. Have a smoke and beer. Hopefully not many of you will ever have to go through this! It was a scorcher today - it's still 88 deg and hazy/humid at almost 10pm EDT. I'm glad I got the exhaust repack and fluids change done in the early morning. Fingers are sore as hell. (Message edited by supamotard on June 27, 2010) |

Just went out on a test ride and boy does she feel great! The biggest improvement was the Jardine GP1 repack. I had 8k mi on the original packing and didn't know how loud it had gotten. It's now quieter than it was when new - I REALLY stuffed it with glass! A fresh fill of formula+ tranny fluid and amsoil 20-50 feels good too. YAY. |
