Comparing to the relatively shake free video taken on Mr.H, some of the shake on videos taken on Eccles is caused by the V twin engine (you can see that when I accelerate from stops) but most of it is due to the way I had to mount the camera, which amplifies the engine shake as well as bumps in the road.
Mr.H's camera mount is on the handlebar where any vibration (not a lot on a 'Wing) is usually damped by my hand on the bar. Unfortunately there is not a good way to mount a camera on Eccles' handlebar that where it could see between the fairing and the sidecar top and wouldn't hit the fairing or sidecar top when I steer.
I considered mounting it to the fairing/radiator bracket (below the fairing) but I'd prefer to keep it where I can see it, not to mention reach it from the seat to turn it on &c.
So my only option was to attach it like this

3 - Installed.jpg
That shook really badly so I added a 2nd vertical member
4 - Stiffened.jpg
That made a big difference so I tried adding a plate to stiffen it more

I have an inexpensive shock mount and did some experimenting and modified it a bit (I studied Acoustics in college and I still remember some of the vibration damping stuff) but before I got a chance to really tell if either of those helped the baffle disappeared from one of the mufflers, engine vibration increased and experimentation stalled with the plate removed and the isolation mount in place.
At that time I added a lollipop baffle to tame the noise until the end of the season and I didn't get around to getting the parts to replace it properly and the previous exhaust was still hanging around so I welded & patched it to get through last winter.
This year
I replaced the entire exhaust system so now I can finally continue with the experiments.
