Retrofit 2005 clutch slave cylinder on 2007

[painman]

Shoot after riding an old HD for almost 20 years I thought the clutch was broke after getting the 06 FJR it was so lite. Hope any mod is for the betterment of the ride though. The spring mod and the Ergo2 mod along with the throttle lock and risers have been great. Only thing I would consider would be a set of "pullback risers", (no old 60's HA pics please), without changing out the trees. Ride safe, PM. <><

If you will notice the slave cylinder piston has a hole in the center that is about 1 /4” deep that receives the clutch plate activation rod. I made a spacer from a small bolt that fills this hole about half way to reduce the piston travel about 1/8” before the clutch activation rod begins to operate.

The design of the hydraulic clutch slave cylinder is such that it automatically takes up any slack between the rod and the cylinder. Conversely, it will also just retract back further if you add a spacer, nulling it out. This is why you don't have to adjust the slack in hydraulic clutches like you did the old cable clutches, as it self adjusts. I am fairly certain that your slave cylinder has just retracted and compensated for your spacer.
