There's been some progress since I posted last.
1) Install Polini 75cc kit with stock head. Convert to 12V: had help putting this diagram together (French Moby /frenchee, and others.) Put a Ducati CDI in, manually retarded timing; removed stator material for maximum stator clockwise rotation. Installed the retarding Pietcard CDI + coil combo. I'm still looking for a good ground, so for now the alligator clips will do. Add the fan to the equation and the the temps hover around 350F.
2) The front fender on the KX65 forks is work in progress, but at least the Shinko Goldenboys tires aren't kicking up dirt in our faces.
Maximum three files attachment limit reached on to the next post. (edited)
