yes Spain

Is the motor mounting adjustable or fixed just like the gas version? In the gas version, the engine mount cannot be shifted. Gear ratio is adjusted by changing the spur and pinion in pair (or something similar to pitch changes in the pinion).

yeah we raced Delta Super-Js and the pinion goes thru bearing in the side plate - well supported
and the clutchbell was totally free-floating off the flywheel/clutch, nothing interconnecting

made engine swaps very fast... like under 2mins once i think?!

Ran Piccos & OPSes back then, with the Delta slide carb & flattop heatsink. Mainly broke conrods.


however when trying to gear lower... the spur becomes so big it runs very close to chassis plate;
the FRP juts out over the edge of the side plate and always clogged up with pebbles = chewed spur.
We'd just gring off like 5mm off the FRP edge to reduced spur damage.

here are specific spare parts of the CK790E kit
