I have a G4S fitted with the orion wasp engine and the kit clutch, still waiting for delivery of a CRF clutch conversion kit. With the standard clutch will it still be OK to run the car as it sounds as if the CRF is a must have. I currently have the clutch gap at .6 and the spring tension around 1.4

Two things that would be recommended for the CRF in the G4S .
Fit the shortest 1st gear gearing ie: smallest pinion and largest spur and get a 1.8mm black clutch spring.
This will allow the engine to really wake up especially the clutch spring.
get the clutch spring tension tight so it slips a lot and back it off a bit at atime till it is what you like.
