SMOOTH SPYDER BELT TENSIONER???

[NancysToy]

My ST had some moderate vibration between 72-78 as new, it wasn't that bothersome that I would have been concerned or worried about it if I didn't know any different. It still has a hair at 73 I can feel once in a while under acceleration but much better.
The belts supposedly stretch some after break-in but mine was 200 Lbs. when new with the Kriket gauge and hasn't changed in 4000 miles. The belts are quite robust and last a long time. It is sort of a crap shoot, some with less static tension have no vibration, I attribute this to just getting lucky that your static tension happens to be set where everything works synergistically and the harmonics just do not occur. This is my take, I don't know if it holds any water or not.

I think your explanation seems plausible. There are variations in machines that change the harmonics slightly from one to another, a little difference in how the engine fits in the engine mounts, for instance. One other thing, everyone's perception is different, so objectionable vibrations for on may seem perfectly normal for another rider.

All very good points.

Since my bike only has about 800 miles so far, and I've never owned a MC or trike before...it may take me a little time to figure out what is normal and what isn't.

I guess I just assumed having only 3 wheels and cheap shocks that i would feel quite a bit of everything and just have to get use to it.
