2009 RS VIking
I recently bought a well used 2009 RS Viking. Clutch was loud compared to my 2006 VK Pro, so I had a rebuild kit put into it, its still noisy. Please see attached clip, can anyone identify what's causing the rattle while its running, still functions fine. Thanks!
 

the idle sounds low from the sound clip.
 
Are you recommending the idle should be set higher to make the rattle stop? If so, what RPM do you recommend?
 
try it at 1500 as the same motor is in the venture/vectors from that era. spec on those is 1450-1550 rpm idle speed.

the 3 holers are notoriously harder on clutch parts and a bit of a rattle on them is considered normal.
 
Did you put new spider buttons in? Did you shim them with the shims that Yamaha offers.
 
I had a guy put the rebuild kit from royal in it (SM-03249). From what I am hearing if I spin the track and the rattle goes away, its fine. Thoughts?

Set idle to 1500, still clunky. Lift the rear and spun the track and it seems to quiet down. Drive the piss out of it and don't worry about it?
 
It's not necessarily the clutch itself but the stub shaft that is inserted into the "dog gear", or whatever it's called, has slight play, which is exacerbated by the 3 cyl. harmonics. Lots of people have tried all sorts of fixes including JB Weld, Permatex sleeve and gear adhesive, drilling and pinning the gear, all but the last one fail. Lots of posts about this problem.




A clutch rebuild or a "Quiet clutch kit" might help to reduce the noise but won't eliminate it.

There's your best answer. Go for it, the primary clutches on the Genesis 120's was always noisy from the get-go, especially the earlier ones.
