I did first start on my -87 banshee just today after teardown/rebuild and heard a loud grinding when pulled the lever in.
Assembled the clutch with new driveline billett basket and driveline drag clutch kit, adjusted the pushrod also.
Lever feels pretty stiff but i think its supposed with those HD springs.
Here is video, a bit over 1min you can hear the sound when i pull the lever.
And yes, i know it has really rich mixture.
