Hello, I registred myself only to respond to this post. I have been working 3 winters to test and improve the clutch to get rid of the rattle coming out the primary clutch. I even "glued" with special aviation silicone the splines between the crank shaft and the taper shaft witch holds the clutch and NOTHING, rattle was always there. Spring, ramps, shims, etc...
This year I replaced the primary with the Power Block 80 from CV Tech #1100-0332 and added all the extra weights supplied with it.
PROBLEM SOLVED! !!! I now have the most wonderfull machine I ever dreamed in my hand!
Do that for your passion, you will not regret it, it is even more powerfull, the 7000 should come equipped with the Power Block.
By the way, I really think crank shaft and taper saft are two different parts so the crank can be lighter that way because it doesn't have to resist the flexion load cause by the primary, only torsion to make the sled foward. I lighter crank means less restriction to acceletation.
