Also...info is starting to come through on a pusher rod and inner basket mod that might eliminate the plate dryness seen from using the stock setup. It appears that the stock clutch needs the inner basket oiling holes enlarging...and no modification to the pusher rod. The size of these holes, and any other info is still in the development stage (go see www.suzukihayabusa.org for further info) but I will endeavour to bring the info here when it is known for definite.
