Almost...

Gaat dit werken ? or Zal dit gaan werken ?

The only thing I am afraid of is the temperature of the shoe what will transfer into the spring, otherwise the shoe has a better cooling....

not very sure on airflow inside the assembly but i would assume an rpm of 30000+ should be enuf for cooling it.

good idea to try this experiment out, though rotational mass should slightly increase with an alum clutch shoe and be a slight drag on the engine.
a lightened flywheel could offset the added mass

Another thing to watch is the effect of the heat to the shape of the shoe, or the amount of expansion of the shoe. I was just heating a crankcase, to remove the bearings, so this comes to mind. I would suggest an added amount of free play to the post holes, to prevent seizing. If tooling allows, possible carbon bushing at the post holes.

OK, today I had some time to give it a try and no, it did not work.

The edge of the shoe did make compleetly contact with the clutchbell but to much slip. Maybe it is the wrong kind of aluminium so maybe a next time with other materials.......

What alloy is the aluminium you used? it looks like one of the harder alloys, because it's so shiny in the pic.

Use a softer alloy...

What about copper?
