I found the plunger, grub screw and barrel on ebay. Think it shipped from Italy. Think it was around $30 usd.
Bike rocked itself off the kickstand while I was putting on my skid-lid. Tackled me and broke the clutch lever. After striping out the allen head, I attacked it with a pair of vise-grips. Messed up the threads on the plunger, wouldn't screw in enough to allow free play in the lever.
