Finally got a chance to put some miles on my 2007 UC. Over the winter I installed the SE Comp, Baker f6f, Baker 30T Pulley and the Bagger brace. I did quite a bit more but these were for ridability. I already had installed the IDS. The Starter clunk is gone and the Primary is quiet. The Transmission and clutch both feel a lot better and fifth gear is quiet. The bike feels a lot smoother and the new gear ratio is much more usable. To me money well spent.
