When I had my 2003 FLTCHUI (40,000 mi.) at the dealer for fork seal replacement, they said the bike had a lot of abnormal vibration so they replaced the front lower motor mount under warranty. I hadn’t noticed any excessive vibration myself, but I figured I just must have gotten used to it. However, since they replaced the motor mount, there is significant vibration between 1000 and 1400 rpms. The bike vibrates like crazy when I downshift to engine brake when it hits that rpm range. I brought the bike back and the service manager told me to ride it for a while and the mount should “loosen up.” Well, since then I have put probably 2500 miles on the bike and it is still shaken. My question is, is there something they did wrong when they installed the new motor mount? Is there something I can do to correct the vibration? That’s what I get for taking the bike back to the dealer.
I would see if the dealer has the original mount and re-install it then see if the vibration is gone. If they don’t have the original I would demand that another H/D made mount be installed and see how it is. I have had H/D mounts that are new be bad and I have had many aftermarket mounts be bad when brand new(find out which they installed). I would also email H/D right away about this dealer, the squeaky wheel always gets the grease. I have had customers do burnouts against a wall and come away with a nasty vibration due to the entire driveline shifting forward, this may not be the case but were also not sure who took your m/c for a test ride after the service . Please be more specific about this vibration when and where you feel it, location on the m/c . I have also seen way to many of these with about this mileage develop what they call flywheel shift or wedge which is a unbalanced internal condition usually caused by over revving. Please contact H/D and make sure that this dealer is made to repair your problem, especially since you did not complain or ask them to correct a vibration problem. Wrench Safe,

When they told me they had replaced the motor mount I asked them for the part. They told me it must have been thrown out because they couldn’t locate it. I searched some other sites for a possible solution and read about the Velva Ride mount that was supposed to be better than H-D. I just received my order for one this week and plan to install it over the weekend. It sure doesn’t look any different then the OEM one, so we’ll see what happens. It’s been a couple of months since the dealer did the work, but I don’t think that will matter. However, if I install the after market mount I guess I will have blown my chances with H-D. But I have the part now and I’d rather solve the problem myself, since every time I have a dealer do something, it seems like something else becomes a problem. I’ll have to think this over. Thanks for the advice.
