Hello; Mike here. I have a Gen 3 with a Carpenter engine that makes 188 RWHP on a known stingy dyno. The bike in crazy fast, and handles very well. It gets ridden very aggressively on the street, and I also do track days. I am getting a lot of head shakes when on the gas hard, especially at higher speeds. I have a Scott's steering dampner on the bike which obviously helps, but I still get them badly. I have the stronger spring on the rear shock from Race Tech, and I have 3 lines showing on the front fork preload. Any ideas from the suspension guru's what to do to lessen the head shakes? Back off the preload? Raise the back of the bike? Slide the forks up through the triple trees some? Any help would be appreciated. Thanks. Mike.
