Jerry and Dave....
This is my 3rd bagger starting with a 98, an 02 and this 05 CVO. The CVO has 12.5 inch Progressive shocks, standard springs, dialed in about 6 turns or so.
The common thing in all of them were what you two were discussing as far as the sweeping curves and high speed stuff.
This past Sunday, I jumped on an on ramp with the 05, ran it pretty hard thru the gears and leaning to the right following the curve in the ramp, probably going 80 or a tad higher. Yup!! there it was again, a slow wobble.
I had it up to 115 one time, 110,,,smooth as silk, 115, whoaaaaa....started out as a nice slow wobble. I backed off and haven't been over 110 since. I was just happy as a clam it didn't go into a tank slapper.
In both cases, the wobble was slow, a slight side to side movement of the bars. Just enough warning to tell me I am outta my element.
My cure is what Jerry suggested, slow down. I was thinking of a true track or the equivalent, now i see someone here tried one of those to no avail. I figure if I want to go that fast,,,Id better buy a bike thats built for those speeds. But I know deep down inside, I'll probably try that true track just for giggles.
