{font{arial,helvetica,New to the site--GREAT SITE/INFO--looks like I have a few minor items to check (wheel bearings, sidestand, etc......went through the "new riders" section already). Back to my question......has anyone experienced instrument panel vibration on their '06 XB12X??? I just bought one with only 3,000 miles on it--great bike--but when the engine revs cycle up and down (mostly down) through around the 2,000 RPM range, I get a very annoying instrument panel vibration. I've seen some Buell Service Bulletins for some older model Buells (1995's) on the Service Bulletin thread that show an "Instrument Panel Stabilizer" that appears to help reduce the vibration on mid-90's Buells, but haven't seen anything for Uly's. This apparantly is a known problem with past Buell models so wondering why Buell didn't see to it that this issue didn't happen on future models. The previous owner (original owner) said he took it in and the Buell dealer at the time just put a rubber pad in somewhere to help quell the vibration but it's still pretty aweful. Before I start taking parts off the instrument panel/upper cowl one-by-one (starting with the wind/bug screens) and seeing which one may need to be stiffened/modified/better secured/replaced, I was hoping someone might tell me where the target problem area might be. Thanks. | ||

Do you mean a rattle? I had that, and fixed most of it by relocating the horn (which may not have been in its original location). I still get just a little, which I think is the clear screen banging on the flyscreen cover. but it's not nearly as loud or frequent. | ||

The original owner that I bought the bike from didn't make any mods to the bike (according to him). I believe him. He "disclosed" the vibration issue to me (in the spirit of full disclosure) prior to me driving 500 miles to his house to come pick it up. The bike has the original windscreen/windshield, but if the vibration only gets worse with a larger windscreen, which I eventually plan to install (the biggest one I can find actually--I'm 6' 5" and don't like buffeting) I will need to be doubly sure I eliminate the issue before installing a larger windscreen. The vibration issue doesn't occur at idle, only around 2,000 RPM. I own a '12 Road King w/TC103 that shakes alot more than this bike at idle. I'm perfectly fine with the normal idle vibration on the Uly. The front of the bike seems to do more than just vibrate. It's a very healthy "shudder", brought on by engine RPM's. The shudder goes away with more (or less) engine RPM's. The front engine isolator makes sense. I will be sure to look at that very closely when I start the investigation. Has anyone replaced the upper locating pins in their windshield with the Chinese screw/rubber grommets sold on Ebay? ....or possibly factory ones? I would think the four-point secure system would be more robust and secure than Buell's OEM two fasteners and two push pins/locating pins system. I've seen pics provided by Arcticktm that really help drive home the point that there is ALOT of stuff underneath that flyscreen. I have the patience to wrap each and every hanging component in fabric to see if I can isolate the problem. Any others that might have an idea what might be wrong or where I should look, I'm still very willing to listen. Thanks for responding. | ||

Thanks. I'll be checking: Front Isolator, Primary chain tension, missing hardware, horn vibration, and windscreen vibration. Will not stop until I find it. I'm currently distracted unfortunately with getting some outdoor house maintenance projects completed before the Michigan winter sets in. The XB vibration investigation may have to wait until the off-season. I'll be sure to let everyone know what it was when I find it. Thanks for taking the time to share your insights. | ||

I kept poking around the awesome BWB site and found this thread that pretty much explains the vibration I'm experiencing... http://www.badweatherbikers.com/buell/messages/142 838/626617.html I looked at my front engine isolator and found there's no 1/8" to 1/4" gap between flange on the hex socket bolt that goes through the isolator and the rubber washers attached to the isolator itself (as shown in the "bad isolator" picture in the thread). I'm sure the engine is bangin' on the front steering head that the isolator bolt is attached to, causing the heavy shake on the front end of my bike. I'm gonna replace that sucker right away! I'll let y'all know if that takes care of the vibration problem. | ||

A new front engine mount isolator did the trick! Installed it over the weekend. No more nasty vibration! Only the "normal" stuff!  | ||

Not sure if I have the same problem... Just bought a 2008 XB12XT, My Brother has a 2007 XB12X. Mine has much more Vibration than his. Like night and day. Not sure where to look. I do get a "stumble" at idle every so often, and it has even died while at idle. Not sure if the vibration and that are related. Other wise seems to run pretty good. The Vibration is felt all over. Rear View mirrors are useless unless the engine is over 3500 or under 2000. Hands numb, feet tingle. I have several pictures, and even a video or me revving it in neutral. I put it all together here: http://www.randpcarriages.com/Buell-XB12XT.html I really would like to get this solved, but really want to just throw money at it. I mean I mind spending the money to fix, just would like to fix it and move on to other projects. http://www.randpcarriages.com/Buell-XB12XT.html |
