Spedeworth / Incarace would like to make all drivers aware of the following rules:-
If using a 1.3 engine, the 1.3 standard Un-modified flywheel must be used, this can be either the 1.3 one piece or 1.3 2 piece flywheel.
You can use the 1.3 dizzy type gear box or facelift big shaft 1.0 box ONLY on a 1.3 engine.
There is a serial number on the flywheels and these will be checked regularly.
NO 1.0 flywheels are allowed & coil pack gear box are not permitted unless using the coil pack engine as these don't fit the 1.3 flywheel.
Small shaft gear box and flywheel can only be used if running the factory fitted 1.0 engine.
No lightning, balancing or modifying of the clutch or flywheels.
Gearbox checks will be carried out randomly & frequently also checks will be made to other parts.
There will be a meeting at the end of the year to discuss new rules etc for 2018 season.
