switching from 4 post to 3 post primary?

Can I use the same weights and spring from my 4 post clutch in a 3 post primary?

The spring may be reused, but the weights will be too light. Post your mods & rider weight, & I'll give you a caliberation that should be very close for your M1000.

Take the weights you were using in your 4 post, add them up and divide by 3, that will give you the weights you need for the 3 post.
