VALVE LASH
IGNITION MODULE & PIN PLUG OUTLETS
To enable inverted use for the Rotec Radial, the following is required:
Fuel Supply:
• Fully Aerobatic Fuel System such as the Rotec TBI
• Electric Fuel Booster Pump
• Fuel Tank with internal flop tube (not available from Rotec Aerosport)
Oil Supply:
• Oil Tank with internal flop tube (not available from Rotec Aerosport)
Valve lash or valve clearance on any Rotec Radial should be set to 0.1 mm (0.004’’), cold engine.
A rule of thumb method for achieving this valve lash is:
1. Seat the valve adjuster to the seat on the head on the valve.
2. Loosen the valve adjuster 1/8th of a turn.
3. Tighten the valve adjuster so it can no longer move.
4. Confirm with a feeler gauge the correct valve lash has been set.
It is recommended that valve lash is checked annually. Please contact us for more information.
Wire numbers on the ignition coil plug are:
1. Negative side of the ignition coil (-)
2. Ground (earth)
3. 3-pin hall sensor plug negative outer pin (black wire)
4. Positive side of the ignition coil (+)
5. 3-pin hall sensor plug positive center pin (red wire)
6. 3-pin hall sensor plug pulse groove (white/brown wire)
7. Tachometer pulse (optional)
Wires numbers are represented by the number of marks on the wire. For example wire 3 will have 3 marks. For graphic
representation of wiring diagram, see the installation guide.
