I didn't want this to get lost in my other post. I have about 2600 miles on my 06 Uly and notice the vibration seems to be increasing between 3500 and 4000 rpm's. I really feel it through the handlebars. I have read that this can be caused by a mis adjusted belt. Anyone else experience this? thx | ||

There's no adjustment on the belt, but it might be the primary chain. An excessively loose primary chain causes increased vibration. If you've got the shop manual, it's fairly easy to adjust. | ||

Orange, I was getting a persistent vibration from 4,000-4,500 RPM. I had the shop to check the primary and adjust it. They did. Now it's smooth as a baby's butt all the way to redline. | ||

Other than a vibration, is a loose primary harmful? I've read here that too tight it can tweak the clutch basket and cause shifting problems. I'm letting mine run a little loose now but then I don't consider the Uly to be in the vibrating-bike category anyway. | ||

Ultimately, vibes equal wear. The less the better. | ||

I had a very strong vibration in that RPM range on the right side of the frame. The dealer replaced my front isolator, and the vibration is gone now. | ||

I'm at something over 23,000 miles and for some reasons vibrations seem to almost come and go from one day/week/month to the next. I think it's mostly in my head. | ||

Mine seems to have more vibrations when it's cold or if I haven't ridden it for a few days. When it's warm and I ride it frequently, it seems to have fewer vibrations. | ||

If your bike gets cold the rubber isolators get harder and will cause vibration. It is just a quirk of the beast. If you notice any extra vibes take note of the temp and it is a little colder than you normally ride you know what it is. | ||

If I drink too much coffee and tea I begin to vibrate at a very high frequency and to cure this I get on my ULY and my natural frequency is counterbalanced by it's freq. | ||

On the primary, "a little play is OK" does not translate to "more loose is better". Just right is just right. Tight is hard on bearings and clutches, loose transmits more shock load and chain slap. Just sayin'. | ||

Thanks for all the input. I'll break out my shop manual and go from there. |
