Default Made a new clutch flower nut retaining screw

Got sick of that tiny, lousy one with a stripped head.

So I got the appropriate length 4mm screw and machined the head down.

Works great.

I know, not very exciting.

This little screw has been a PITA since day one. Soft as the dickens, lousy. So you can see it's easy to find an M4x.7 screw with the same length. But alas, it must be chucked up (the drill works fine) spun and ground on a grinder (or other - file, grind stone, moto tool, emery cloth) until the head diameter is the same as the cutouts in the flower nut.

Then some careful material removal on the thread face - because if you don't do this the screw head will hit the clutch cover.

Done. Now adjusting the clutch if fun with the SBP cover mod.

I like the simple and effective improvements you make to these bikes. I am really enjoying my SBP shift kit on my Moab.

Peanuts compared to Norman. Dude can roll pipes!

I noticed that the clutch pressure plate contact surface bells out, losing valuable contact area. Need to think on that one.

Plus the the parts don't really run concentric. Vibromaster.
