Electronic Ignition Wiring Instructions & Wiring Diagram
1 First remove the original flywheel, stator plate, H.T. coil, rectifier or regulator and wiring loom.
2 Fit the new loom to the frame, also fit the new C.D.I. unit and regulator. (We recommend fitting these two items under the rear of the frame where the original coil was located, C.D.I. unit on the same side as the coil, regulator on the opposite side), Using electronic mounting brackets.
3. Fit the new stator plate to the engine with the three locating bolts central in the slots. Place the new flywheel on to the crankshaft, but do not tighten.
4. If using a dial gauge to set the timing, the cylinder head, exhaust and head cowling must be removed, (a timing disc can also be used for the same job).
5. With the cowling and cylinder head are removed you can now fit the dial gauge to the top of the cylinder. Rotate the flywheel until you find the T.D.C. (top dead centre - the highest point that the piston travels up the cylinder).
6 When you have found the T.D.C. set the dial gauge at zero. On the outer lip of the flywheel there is an arrow which faces the magneto flange. With the dial gauge set at zero at T.D.C. make a notch on the magneto flange opposite the arrow on the flywheel. This is now your T.D.C. mark.
7 From the T.D.C. mark, rotate the flywheel anti-clockwise so the dial gauge rotates to 2.0mm/19 degrees (if using a timing disc) for GP electronics or 2.5mm/21 degrees for LI/SX electronics (if using a timing disc).
8 Again at this point make a notch oppositie the arrow on the magneto flange.
9 Looking through the window on the flywheel (five o'clock) you will notice two lines inscribed on the outer edge of the flywheel. These two lines have to match up exactly with the two lines on the stator plate pick-up box when the flywheel is at 2.0mm B.T.D.C. (before top dead centre) or 19 degrees B.T.D.C.
10 If the two sets of lines on both stator plate and flywheel do not line up, you will need to remove the flywheel, slacken the stator plate bolts and rotate the stator plate in the direction needed to line up both stator and flywheel. When the two sets of lines meet up exactly your timing is set and should not need altering.
11 Before fitting the flywheel, make sure both taper surfaces are dry and clean, and that the key is undamaged and a firm fit in both keyways. The centre nut has a spring washer below it, and the flywheel must be held with a flywheel holding tool whilst the nut is tightened (anti-clockwise) with a torque wrench to 50 lbs/ft (6-6.5 kgs).
12 Refit cylinder head and cowlings etc.
13 Change all bulbs from 6Volt to 12Volt.
14 Follow the wiring diagram as supplied with the kit.
