I was out riding with my husband and my friend and we had just come over the high rise bridge from beaufort to morehead city and was sitting at a traffic light. When the light turned green and I went to go, the rear tire would not move and a very odd/loud noise came from the rear of the bike to which my husband said…
The vehicle began to hesitate and the contact was able to pull off the road and shut off the engine. The vehicle was able to be restarted a few minutes later, but the noise grew louder. The vehicle was taken to the dealer and they stated that the failure was ongoing and harley refuses to issue a recall.
The horn does not work. I have had it back to them twice, they oil it, I get it back on the road, and it doesn't work. The service department read me an interoffice memo stating basically that harley recognizes that their horn consistently does not work and recommending several things that can be done to fix it, but…
The handle bars on my 2006 hd softail motorcycle are not aligned correctly. I purchased the bike and notified the dealer who attempted to fix it. They contacted hd representative who looked and rode the bike on 10-20-05 and stated it was within specifications.
