I use a Manx type clutch behind my 850 motor with a single row primary chain and Jawa  speedway engine sprockets.  I have made the splined adaptor to allow the engine sprockets to float and be quick-change.  There is a quarter of an inch difference in the length of the gearbox mainshaft -  must be coped with. You might be able to recess the back of the Manx clutch, but I doublt it.  Alternatively - you could fit a Dominartor main shaft.
