Hey everyone, I'm new to this forum and glad to finally be able to be a part of it!
Bought a 2004 xb12r with 9k miles from my brother in law and have loved every moment of ownership until just recently. The other day my buddy and I got caught riding in an absolute tsunami, us an our bikes made it home perfectly safe with no problems. Had the bike in the garage for about a week, went out to take it for a spin and found that it wouldn't start without providing a little throttle and when it did start it was only running on the rear cylinder. I pulled the front plug, it was completely fuel fouled, cleaned it up, checked the spark plug wire and coil for signs of damage or corrosion and then checked for spark. Plug seemed to be doing its job so I tried again.
Same thing. Front cylinder just not running.. Removed the front fairing and checked every connection for moisture and everything looks dry.
Finally I let the bike run for 30 seconds or so on just the rear cylinder and the CEL illuminated. Trouble is, I don't have an ECM Spy.. Has anyone ever experienced a problem like this before? Ideas? Any help would be greatly appreciated. Thanks so much guys |

First of all, welcome to BadWeb.
I'd pull both plug wires (masking tape with F or R to id which one is which) and make sure the ohmic value of each is approx. the same. Read one with an ohmmeter, then the other. If they are close, then it's not that.
Next, I'd check the connections at the coil (meaning the coil wiring itself) and make sure they are tight.
Next, replace the plugs. |

Ditto on the welcome. And to second what Two season said, replace the plugs. I have never had good luck cleaning a fouled plug. Never seems to work.
As to the trouble code, pull the plug to the data connector. With the open end of the plug facing you, and the connector lock at the 12 o'clock position, the pin at 2 o'clock is pin #1, and the pin at 4 o'clock is pin #2. Jumper the two together (a paper clip against both pins works) and read the trouble codes off of the CEL light. You will need a service manual to decode the numbers you get.
Hope this helps, Dave |

What Dave said about the diagnostic data plug. I'm not sure where it's located as I haven't graduated to the XB's...yet!
I don't have a manual for the XB's either, otherwise I'd call out the Diagnostic Trouble Codes for you, lowest to highest number.
If you have a Radio Shack store nearby, go in there and buy what's known as a "wire jumper with mini-clip ends". This is a spring-loaded curved mini-clip on both end with a short strand of wire between the two. Much easier to grab the pins as you can go straight in or at an angle with these type of jumpers. Paper clips not so much.
I concur with Dave regarding the plugs. Fuel fouled don't clean up real well. And the service manual cautions on cleaning with a blaster as you very well may damage your engine if there is any residual grit in the plug. |

Thank you all for the warm welcome and all the great suggestions!
After I finally got off work, (stuck swapping an engine in a passat w8  I checked the resistance on both wires and both were equal and within spec. Pulled the plug again and tried cleaning (HD didn't have them in stock and couldn't get them until Monday?  but this time with a wire brush and then blasted out all the grit with brake clean. Charged up the battery and performed a hard reset on the PCM. Bike fired right up!! I was so happy I put it all back together and went for a ride. Yea it's 39 degrees and I don't have proper cold weather gear, but so worth it.
Now I just haveto figure out the slight hiccup while at cruising speed and with any luck I won't run into any more issues in the near future. Im going to replace plugs and wires as soon as i can then once i get ECM spy perform a tps adaptation and go from there. Thanks again guys, I greatly appreciate the quick response and all the input! |

Are the M2 plugs not the same? I have been using the 10R12X (27794-08) HD plugs. It is said they do not foul as easy and have a coating on the threads to ease install and removal. So far I have had good luck. I always keep a spare set on the bike and a few at home. I used the DCPR9E's but had what I thought was fouling issues. |

Oh and as far as the wires, I bought a race style plug wire kit for an 8 cyl. automobile. Made a couple sets for the bikes and still have enough for a few more. Just have a tube of silicone grease to get the boots on and a good crimper. Inexpensive and they work super.

Good luck. |
