hey, just changed my oil,tightend my belt bike has 2500 miles. now have a good vibration at highway speeds,
tried running 4th still there, feel it in the pegs,grips and gas tank.. was never there before? belt to tight? to much oil? not totaly sure?

Is it there ONLY at 60? Does it go away if you go, say, 70? If so, then it sounds like a balance problem with one (or both) of the wheels. Maybe one of the balance weights fell off (my front has one that was there from the factory), but If you tightened the belt the rear may be just a hair off. My two cents.

Mine does that also. Tech says normal vibes.

vibration was never there before! goes away about 80-85mph

I can't say if it's normal or not, but mine only has a few hundred miles on her and I don't have any vibrations that seem abnormal. Certainly nothing that transmits into the bars or seat. In the mirrors, I can clearly see those that are behind me -- no blurry out-of-focus blobs that would indicate moderate bike vibrations like some stylized Hollywood production. So, running through the possibilities, one has to assume its the rear tire sine that is the last thing in the engineering chain that was mechanically altered (based on your earlier post). Consequently, you might re-look at the belt tension just to make sure nothing is amiss.

Hope you figure it out...nuances like this are maddening.

Its probably the belt. These things are so tempermental and difficult to adjust properly! Chains are much easier, but louder and dirtier and more maintenance...but at least they're easy to adjust.

most likely the belt man...

i think i figured it out, first thing i found was the axle nut was not totally tight, then loosed belt slightly, now pretty good...

I went through the same thing. Adjusted belt to specs with special guage and all, but just kept thinking to myself that the belt was too tight, because I too was getting vibration at 55 to 65. I loosened belt just a little today and is much better. I guess we can't always go by the book!
