A year ago I purchased a new XB9SX from Calif.HD In Harbor City Ca. The bike began experiencing some minor problems right away, with the tach and speedo not working, (the dealer could never fix it). Then at about 2000 miles the back spark plug fouled. I fixed it myself by cleaning the plug.
At the next scheduled service, I notified Glendale HD about the issue. The bike checked out OK. A few miles later, again the rear cylinder fouled, and since it was at the 2000 mile service,I took it to Glendale HD, where the bike checked out OK once again. When I got the bike home, the plug fouled instantly. I had to replace both plug.
This last Saturday, at 5000 miles I took the bike into Calif. HD for the scheduled service, and they called and said the top-end was shot, down 40% compression on the rear cylinder, and 10% on the front. It was using oil too.
I have ridden motorcycles for over 30 years. This is my third Harley product. I let the bike warm up for at least 5 minutes before I touch it, change the oil all the time, listen for noises, etc. In fact, I break in Harleys for a rental place in Compton Ca. (Moturis). So i know my way around a big v-twin four stroke.
This sucks, as I really love the bike, and I don't want to off it. It's 80 degrees in Burbank right now, and I'm stuck on a 36 year old CL350 with un-synched carbs. Help. |

Warming up for 5 minutes sounds not good tome. One- Maybe two minutes is all you need,
The symptoms you describe are consistent w/not air cooling. I had this situation on a basket case*1399 I had. I don't have a resolution - Isold the bike after I got it working ok. |

Most H-D mechanics agree with a longer, lower RPM warm up. Five minutes is on the longer side of that, I like two minutes.
But it is not going to overheat or hurt anything in five minutes.
The most often heard reason is to allow the mixture of aluminum and iron parts to expand from heat and put pressure on the gaskets before raising the pressures much. Leaking cylinder base gaskets are sometimes blamed on not warming up enough.
I always gave my M2 two minutes, I do the same with my FXD. It just part of the ritual. Start up, listen a little, gear up, then ride. :>

I don't let my buells ideal any longer than I have to on the stand. Just get moving and light on the throttle for a few minutes. Never have problems with fouling plugs.
