It's just a plain centrifugal clutch for now which runs into PMR jackshaft, but I'm looking into a 3 or 4 disc setup (Bully or Diablo). Not sure this jackshaft type will take the beating a disc clutch will provide with a 3500-4000 rpm stall speed. It "launches" like a slug now, no launch off the line, but pulls well at higher RPM's, so no problems with this jackshaft. The 3d manual clutch seems to be a problem with some of the posts I've seen. A lot of posts about buying it, then going back to a more conventional setup (disc type), since people don't seem to enjoy it. Not sure why exactly, but a disc seems to be the best bet for reliability & tuning on next one.
The final drive for now is 7.38:1, so with the 19" tall tire, 8000 rpm is just 60 mph. I can change this to increase speed, but I found a road which is lightly traveled (& patrolled) so the real shake-down will need to be chosen carefully. It's a bout a 2 mile long straight with some small hills & decent paving. I'm looking into a better rear tire now & have a line on one which will work better. The Kenda is just rated for 43 mph, but it's been a bit faster than that.
Planning on a VC 460 at some point, when I get around to it ($$$), but for now the modified 212 will have to do. The 460 will require a bunch of changes (3/4" jackshaft or torque converter, different motor mount & location, etc.) so I'm not in a hurry to do that one yet. Still playing around with this for now, but it's coming along.
