I found this article on the thevincent.com has anyone done this mod? and if so, do you have any pictures? I've got a V2 clutch and have just purchased a set of clutch plates from the club. Does anyone know if these plates should run wet or dry?
Thanks

Increasing clutch lift for multiplate clutches: The kickstart cover's clutch arm (G91) adjusting screw has a ball at the end where it contacts the G91, the fulcrum point of the G91 lever. Moving this fulcrum point further away from the pushrod increases the travel at the pushrod. This is accomplished by removing the cover and replacing the adjusting screw with a short, solid, flat faced dowel pressed into the bore of the cover formerly occupied by the adjusting screw. This bore is non threaded and larger than the 3/8" adjusting screw, I can't remember the exact size, I turned mine up to fit tightly. The G91 will now contact the dowel at it's lowermost point (you may have to relieve the G91 a touch so it hits in this spot) instead of in the center of the cover's bore where the ball of the adjuster screw previously made contact with the G91. Also necessary is to trim the dowel to length such that the G91 is perpendicular to the pushrod at their contact point when the G91 is at half travel as adjustment at the cover is now eliminated.
An alternative suggestion was to simply use a flat faced screw in place of the standard adjuster. I too thought of this but decided against it for several reasons: the leverage increase would not be as much as with the larger dowel inside, you would be putting a side thrust on the threads in the cover and the screw's threads would deform in use where they contact the G91 making removal impossible without stripping the cover. I also thought of using a screw to push on the back of the dowel for adjustment but this takes the dowel off it's firm seating in the cover bore and would cause rocking of the short dowel.
Hope this better describes it. Again this was not my idea but it sure works for me. I found with my multiplate clutches the standard lift was not enough to make clean, crunch free gear engagements. It does increase effort at the handle bar slightly, up to about half that of a Commando. The nice part about this is no Vincent parts are harmed. Easily reversed by replacing the dowel with the standard adjuster. Paul Zell 5/16/07
