Just picked up Mag arms for my 800 twin.Was thinking of going with 23g pins and a softer primary(130/200).Am I in the ballpark or is there a better proven starting point.The sled is otherwise stock and is running at 0 elevation.Can anyone help me or direct me to someone who can?

ok here is my set up(from big john)i have a 136 1.25 track also and rkt head


130-200 blue orange
21.6 pins
secondary white a2(21-22lbs)
stock ramps 300
stock helix 53-47 with goodwin buttons
gearing 25-44(i have mechanical reverse)
on clicker1 im running 8000 rpm..clicker 3 running 8400

have 200 kms on the mag arms and so far and like it alot more than the stock clutching,anxious to see how it is in deep powder..was thinking of adding another gram or two so i can click it back to 3.

Pantera,thanks for the info.I am also running an 1.25 with 25/43 gearing.Yeah it sounds like you could use some more pin weight to bring the rpm down a touch.My adjustable pins only go to 21.6g so i'll get a set of 23g and try those.Thanks again. :)
