I have a new 2009 XB12XT with 750 miles on it. I changed oil last week and didn't touch it again until today when I started it. It ran fine for 30 seconds than started running on 1 cylinder. The dealer is 6 hours away. I'm sure it's something simple. Any ideas where to start? | ||

spark plugs. I'll bet it's the front that isn't firing. If you tend to make short trips on your bike plug fouling can be a problem. They like to have a good run  | ||

Change out the plug on the non-firing cylinder, it is almost certainly fuel soaked. My 09 XT did the same thing (the temp was 26 deg.) I changed the front (non-firing) plug; it was soaked. I still don't know why it flooded, but it hasn't happened since. Mine had 430 miles on it at the time. | ||

My 09 XT fouled the front plug somewhere around 300-400 miles. Changed the plug and hasn't happened since. | ||

absolutely they are fouled all the time from dealer and cold weather starts. Important do not blip or touch throttle on start up and do not run them for 5 sec and shut em down this will almost certainly foul a plug | ||

I thought I read that beginning in '08 Buells introduced a procedure for clearing fouled plugs? I don't remember what steps are involved, but check your owner manual. | ||

While checking the fwd plug I found that the plug wire was not plugged into the coil. It must have vibrated off. I hope this doesen' happen often. It took me an hour to get it plugged back in. Thanks for the help. | ||

It probably wasn't all the way on from the start. They don't vibrate off, as long as you get the "click" of it getting on the terminal right. | ||

It's not fixed like I thought. Bike started running on 1 cyl again. Fwd plug is sparking, and is wet. WTF, this is a new bike. I have an Arizona bike trip planed and I need to leave in 4 days. Any more ideas? I'll take the BMW if this keeps up. | ||

You will miss the fun if you do. Did you change the plug? | ||

It is normal for plugs to be wet fouled on new bikes. Change them out and forget about it. | ||

What spark plugs work best? I'm at work right now, I'll pick them up on the way home. I tried searching but it didn't work. | ||

Vrod plugs | ||

I bought a Champion plug as it was the only thing I could find. I installed it and the bike fired right up on both cylinders. I'll try to test drive it tomorrow (we just got 4" of snow). I'm still puzzled because I had gas and spark but it would still not fire on that cyl. I hope it's fixed. What NGK plugs should I get, DCPR8E or DCPR9E? | ||

Print this, as brumbear said, you will use the vrod plugs. http://www.harley-performance.com/harley-spark-plu g.html | ||

Blackdog - It is easy to create spark in open atmosphere. However, when the plug is installed and under cylinder pressure, it is more difficult for that spark to jump the gap. So if your plug is just a little bit fouled it won't jump while under pressure. Replace the plug(s) and if you start it to see if works, let it run till it gets hot, so you don't foul out another plug! | ||

use the 9"s, the plug that has the hat on the end , the other with the screw on hat-cap has a weird 18mm hex and with 3 plug sockets I still had to use a open end.there is about a dollar difference but in this case a ten dollar head ache.napa has them | ||

for future reference, my bike has chaffed through 2 sets of spark plug wires. and i had a problem where the harness chaffed on the shock cannister and shorted out the control for the front fuel injector in the ecm. after repairing these and various other wire chaffes, i have gone through the whole harness and heavily protected it with hockey tape. the wiring is the achilles heel of these bikes. be careful. and get some new plugs, learn to rotate the motor, and put them in so the wires line up without touching anything. you'll thank yourself in the long run. | ||

Your bike has an awesome feature to help with fouled plugs. If you suspect you have a fouled plug, turn it off. Flip your kill switch to on, open the throttle fully, and turn on the ignition switch. The plugs will fire, and burn off any crap that's accumulated. I had some serious fouling issues when I first bought mine. Now that I do this, I've never had to change them. |
