Washed the bike yesterday (2nd or 3rd time since Jan.- 16k miles now). Started normally this morning for the commute. Got moderate rain from about 20 mile mark (35 total) but everything normal until I rolled off the throttle to exit the freeway and then rolled back in- it dropped a cylinder. Would barely idle, but at times under throttle it would catch for a few beats then miss again. Got it the 1 mile to work, parked it and restarted it at noon- had been in showers from 6-9 am then clearing and warm. Started up normally and idled ok for 3 minutes then shut it off until 5 pm. Started normally, ran for 30 seconds then started one-lunging it again. Rode it home- at times reasonably normal operation and at times a dead miss. Let it idle on one cylinder in my driveway long enough to find the front pipe much cooler then the rear. Pulled front plug- looked normal- not even fuel fouled. Removed plug wire- found rust-red oily residue on high tension tower, in the tower and in side the wire boot. Apparently the spark had been flashing over this junk, the origin of which I have no idea. Cleaned it all off with electrical contact cleaner, reassembled and rode it for 10 miles. Everything ok so far. Will see again in the morning. It almost looked like the coil itself may have been leaking. Anybody know if these coils are oil filled? |

I had the same thing happen to my bike. I replaced the coil as a safe guard. |

Paul56, Check your front plug wire. Mine was doing the same thing. While I was changing the plugs, I noticed that the front coil wire was lying against the wiring harness. There were arch traces and the wire was rubbed nearly halfway through. It was also not totally seated in the coil and there was some arching there as well. |

Put some dielectric grease on the plugwire ends & it will not come back! |
