It may not be confirmed before, I never thought to update...
2 SPEED NOI clutch internals are identical to VIP.
I'll be adding it to the wiki.
the clutch bell a little toothed washer spot-welded on. Mine had weak welds. the washer broke loose and the bell itself bit the dust. I'd suggest anyone building a high performance Garelli 2-speed reinforce these welds.
Update is, Martin mailed me a care package, contents: One VIP clutch bell, One hardened brass pedal shaft pin, One size 92 dellorto jet, One set of homemade rubber nipples for VIP starter plate, One handwritten note, a tracing of VIP clutch rubbers saying "remember we need ND30 to live!" and a small drawing of a cock and balls.
the VIP clutch bell worked like gangbusters and I was up and running in time for WB2.
So if nothing else; it's a big deal because together, through teamwork and comradery, Moped Army regained all-but lost compatibility knowledge of the rare 2-speed NOI.
