Increased the preload on handlebar rubber mounts

The stock K11 handlebars are loosely mounting in rubber grommets sunk in the upper triple clamp. The loose rubber mounting of the handlebars sacrifices handling "feel" in favor of vibration dampening. Since I did not feel that the vibration of my K11RS was objectionable, I chose to tighten up the handlebars by removing some of the play in the rubber mounting. I used some large copper washers, with an IDD large enough to slide over the handlebar mounting stud’s collar - I seen to recall that the ID was ~20mm. I removed the nut holding each handlebar clamp onto the upper triple clamp (through the rubber grommets) and slid the copper washers onto the stud. I then re-attached the mounting bolt, pressing the copper washers into the rubber and removing a significant amount of the free-play in the grommets. The vibration felt in the handlebar is still quite insignificant (IMO), and the front end feels tauter and more connected.
