I've got a brand new set of EBC heavy duty clutch springs, part number CSK145, that were only taken out of the bag to look at but have never been installed. These are supposed to increase the clutch's force by 15% according to EBC.

I ended-up going with a set of clutch springs from Brock's for the Katana as I was buying a bunch of other stuff from them at the same time and got a wild hair.

I'll do a whopping $14.00 shipped anywhere in the continental US for these things as they're going to sit in a box in my basement only for me to stumble across them 8 years from now while I try to figure out what bike they even went to.

Help me help you...
