“I own a 2008 harley davidson flhtcui. I have had it in the shop three times because of this same problem. It has an electronic throttle. It will only idle. Right now. It has been in the shop for 3 weeks and the dealer claims they cannot get the needed part for another 3 weeks. It is an upgraded part. I feel a recall is warranted. It did this when I was going down the road.”
NHTSA complaint #10406003, filed 2011-06, 14,100 miles“While riding in residential area bike began lurching and unable to maintain constant speed or RPM. Took to shop and they stated bike did not have any codes displaying. They lubricated all connections on throttle assembly and it temporary resolved issue. Now when I start the bike the throttle is unresponsive and bike is not able to be driven. Sometimes shutting down and restarting will temporarily resolve issue, however, bike is not safe to ride. I believe this is a safety issue and warrants a recall, however not recalls to date.”
NHTSA complaint #10649933, filed 2014-10, 6,500 miles“My motorcycle when I started remained at high idle and would not reduce to normal. I was with a group of riders who were leaving so I took off as is and when coming to a stop the bike only slowed to 2000 RPM's almost causing me to run into car ahead of me. This problem occurs intermittently and motor company instruction was to use a idle reset procedure consisting of turning the ignition on-off 4 times. This worked for a few starts then would occur again. …”
NHTSA complaint #10275198, filed 2009-06, 11,570 miles“I had just got on i65 heading south. I went maybe 2 miles, and all of the sudden, my motorcycle acted like it had just ran out of gas. Or somebody had hit the kill switch. I know it had gas. As it was winding down in revolutions, I tried everything with throttle, kill switch, ignition switch. When I finally stopped, I tried starting it, nothing. It acted like I had no gas. I opened the tank and rocked the bike a little, and I had at least a half a tank like my gauge read. After getting it home I punched my VIN number in to he's recall page, and there was a recall for the fuel filter enclosure. …”
