Is there a rule of thumb for lowering RPM's when adding rivets to my drive clutch. (i.e x grams to the toe will lower x amount of rpm.) This MM is turning 9400 rpm w/ triple pipes and I am trying to get down to about 9000. I added alum rivets to both holes and it hardly changed, I am going to use steel ones next.

Thanks

weights

Check the Snowmobile Tech pages at http://www.totallyamaha.com/.
Lots of user setups and information, with pics of different rivets, etc. I will check with my son as he has a chart for 97SX weights based on the elevation your running. Mods change the recommendations, but good baseline. PM me if you want a chart for stock 97SX.
