I don't but with this style fly weight the overall weight isn't much to go off of. It's were the weight is from the pivot point that makes the most difference.
What he said, the arch of the RCOR weight is way different than stock. It's got a more pronounced arch shape.

How much did it bring the rpms down? I like that Idea of lower rpms. My ranger has lower rpms at 50 mph than the my Krx

Playsndirt,
See pics of mph v rpm. Conditions are, fly weights pictures above, no primary spring. Test was done this morning on blacktop that was very near dead flat.

Just checked mine, no primary spring, black top, 27 mph 5150 rpms, 53 mph 7500 rpms. Looks like your going in the right direction for my likings, can you get lower yet ? I would like that very much.

I don’t think I would try to lower the mid range rpm any more by manipulating the weights. The higher ramp puts you in clutch phase earlier and takes low end. So no, by weights alone, I don’t think I can get the rpm lower without killing performance somewhere else. It’s a balancing act with these clutches and I’m no pro at all. I’d love to see others take a shot at this and I can share cad models if anyone is so inclined. Have a good day all.

What do you mean by billet? In my world (mold making) billet is usually referencing 6061 aluminum. We cut these weights from a bar of 4140 steel. If you’re thinking of cutting them from aluminum billet, I have zero confidence they would last.
Billet is compression forged aluminum that is CNC machined.
