00137 Honda 1980 C70 Passport / Cub

Phil's got my old Aermacchi, but I'm currently tuning his Honda Passport C70. Aka the Cub, it is the most common motorbike on the planet. This one was not idling at low revs, despite having the carb cleaned. On inspection, the bamboo points armature that is actuated by the cam on the flywheel had worn down to such a degree as to not open the points. This was resolved by simply adjusting the points. The oil centrifuge was de-sludged, and the gaskets replaced. Battery, though it holds a charge, probably doesn't have much life left to it. I'd have liked to take a look at the tappets, but the damn covers are seized to point where removing them would destroy the covers and possibly the threads on the head, so that's just not gonna happen. 

Now you see the engine.

Now you don't.

Sludge...wish I could get my guitar to sound like that looks.

 Pretty clean.

 Oil pump is fine.

 clean enough to pour oil on.

3rd world manufacturing

 Screwed into the case half...pretty ingenious design, so des ne?

On to the points! 

Points aren't moving. That there's your problem.

 Melted and corroded and generally non-conductive around the ignition and the electric starter circuits.

 Many hours later:
