RE: Primary Noise
knocking could be a loose compensator. I would pull the cover, inspect it and make sure its tight and not bottomed out on the crank splines. Some require a shim availible at the local dealer. Also a visual check of the chain and tension would be a good idea as i have seen the plastic crack before.

RE: Primary Noise
I agree, I had an almost the same problem, turned out to be a loose compensator nut. I opened up the primary inspection cover, got my fingers on the outer comp cover, and was able to turn it by hand.
The sound was horrible, I though the bike was literally falling apart on the inside. Catch it quick to avoid other problems. I rode my bike another 50 miles or so before figuring out the problem and it cause damage to the rotor.
Loose comps are a common problem...but an easy fix. If it is a loose comp, no worries, just pull the primary, inspect all the parts, if everything looks good, clean the threads on the comp nut and crank, apply red loctite, re-torque, shim if necessary, and you'll be good to go.

No need to remove the clutch. Follow the bulletin M-1170. If you want a copy PM me your email address. You will need a primary locking tool &\\; torque wrench.
