2003 rx1 primary clutch vibration

[anthony Moccia]

Hello guys, got a question,,
Got a vibration coming from the primary clutch, it snakes the belt, then shakes the secondary, goes through the shaft , into the chain case, rattling the chain, sounds like it's grinding, and sled not even moving,
Stock primary, nothing done to it,,,idk

Ran drag with it yesterday, stock,, but got some holes in air box jetting at 160 main jets, rips to 10k,
I lost by an inch,,,

I think these rivets on the primary clutch weights are making the clutch rattle

I weighed the primary clutch weights and there off like 1,2 milligrams.

i think it is time to pull it apart and check all the bushings in the primary weights and rollers. they do wear.

1 of the weights was .7 mg off, I had 2 sets mixed 1 in,,,,,

Sounds like burnt spot on belt. Put a new belt on, see if problem goes way.
