John sent me photos and notes on his adaptation of a Greeves clutch to fit an Interceptor. This unit requires no machining - the only fitting is to use spacers to line up the chainring with the front sprocket.
The unit is from a Greeves 380cc "Crosser" - I am guessing that is a Greeves motocross machine. The cost last year was L350 - 350 pounds GB. The vendors contact info is below.
John has no financial interest - nor I - in this modification. John has offered assistance to anyone who needs help installing it. His contact info is also below.
My understanding is that these photos are of the Greeves unit:

Hi John
Yes I have all parts for these clutches
Bronze plates are 6.10 each
Complete clutch is 350.00
The above prices do not include postage & vat @ 20% Regards Simon"

Nametab Engineering, Redditch, Worcestershire

Note from John van Ravenswaaij:
"There is no shock absorber in the clutch. Never have felt it as a disturbance,
I have replaced the shock absorbers in the rear wheel.

There is no machine work on the clutch at all, straight on the shaft of the gearbox.
Only line up with the front sprocket with the washers if necessary. I used one to line up.
I have used 1 old clutch spring with a Teflon damper and an inner bolt to span the chain spanner.

Use Loctite to fix the nut of the shaft to fix it.
I have drilled a M3 thread in the clutch to fix the nut extra.
The clutch is only suitable with a push rod.
The same push rod as the original Interceptor clutch."

Hi Al,

Thanks for posting the pics.

The clutch is from a Greeves 380cc Griffon motocross bike.

Regards,

John
