“2007 harley davidson flhtcui, experiencing intense heat from the right rear cylinder, when the bike is stopped in traffic it is unbearable, I am fearful it will burn the underside of my right thigh. Discussed with the dealer and was told, there is nothing that can be done. It was suggested that I remove the lower fairings, but this had no effect on the heat when the bike was stopped. As I said, I am afraid I will be burned by this.”

After riding it for a while the first day out with some friends visiting from california the rear engine, cylinder got unbearably hot. There where points that we wanted to jump off the motorcycle.

NHTSA complaint #10242155, filed 2008-09, 14,000 miles“As I was riding down the road at approx. 50 MPH in 5th gear I noticed a drop in oil pressure and a noise from the engine. I pulled the bike over to the side of the road and shut it down. I waited for a while and restarted it. The oil pressure seemed ok and the engine was quiet. The same thing happened three times before I got home. I called my local harley dealer and they picked my bike up and took it to their shop. After they stripped the engine down and checked it out they told me the crankshaft runout was way beyond spec and was starting to wipe out the oil pump. …”
NHTSA complaint #10250125, filed 2008-11, 5,000 miles“I purchased a 2007 Flhtcu in march 2007. Since the weather has warmed, up I have had heat problems with the engine. When riding on days where the temperature is 80 degrees or above, in slow traffic (0-10 MPH), the engine puts out a large amount of heat that causes the backs of my legs to get very hot. If I am riding in traffic, in these conditions, for more that 10-15 minutes, I have to get off of the bike to prevent being burned. I have discussed this with several dealers and they said that this is normal. (note that my 2004 harley does not do this). …”
