Mick's 70 Lowlight

Finished off machining the flywheel. I've probably taken about a kilo off of the weight. I also 8 doweled the flywheel and crank. As I didn't have a jig, I used my indexing head to drill out the flywheel and then spotted through the flywheel to drill the corresponding holes in the crank.

As the fan-shroud was dry, I fitted up the ignitor coil drivers and coil packs. You can see where I cut a hole behind the ignitors to allow air from the fan to cool the rear of the ignitor. This should work much better than just relying on a heat sink.
