Don't know if it was the manicslamander 12oz bar weights or the Dr. Pulley 26gr sliders I installed last night, but no more vibrating mirrors.
BTW @ 55MPH RPM is 4500
Can actually see whats behind me now.
Also did the poor mans seat back modification and that provides a wonderful back rest. Cost $7.00 for bar stock and 4 bolts. Great idea.
Also changed into a Givi 214DT windshield after I ruined the original by trying to polish it with Meguiars plastic polish. Threw that stuff in the trash. The 214 Givi is so nice. No more wind noise. Can actually hear my wife behind me speaking in a normal tone of voice
Have found the sweet spot now for this big old scooter.
Not changing anything else.
