If I remember right (which can be wrong, as I am now aged 45+) SP was the Sport Production Class (nowadays known as Stock-Sport Class) and FIII was the "open one". In the SP they've been running also the NSR etc against the 400cc four stroke. The bikes had to be more or less stock.
In the FIII they've been running without airbox etc...
These bikes where also running at IoM for example, and in a country I can't remember they've organized a cup with the 3MA's (SP Class).

BTW, this was the reason for me to go with TM32 (no SS) and open airbox.. I hope these values in the sugo manual will be a good way to start jetting

Found a video of nice 2strokes at the Assen TT circuit.
The 3MA flooding Assen with engine sound. Pushing 3rd-4-5-6 from 1.52 to 2.05
Some really nice bikes at full revs (-P)
