Agree, never had stiff clutch lever issues with my 750 SF0 unless the clutch cable or clutch stack was DIRTY. One thing I recommend is get rid of that stupid lead puck in the lever as it will break - Replace it with a stainless nut that you round to fit, drill a cable sized hole, splay the cable end and fill with solder or lead.
Or else carry a Vise Gripe tool with you when it brakes.
Could easily shift with my center index finger when the motor was running - With the motor stopped was a different matter.
If your really in a FIX you don't need a clutch on a Breganzie - Just BANG it - Can't do that from a Stop unless you wind the starter out - Or use that Vise grip with a broken cable - LOL
I preferred that Manual Laverda Clutch Cable over most Hydraulic Controls. Why? - A twitch and instantaneous.
One of the best manual cable clutch mechanisms I've ever used and second nature to adjust if you have any experience with one.
