help with clutch weights on mountain max 600

[waynemags]

hey all. new to us 2001 mm 600 141. has 8DG weights with rivets. not sure wich rivets yet. any ways it seems to engage pretty high. high 6000 ish.spring is y/w/y. any ideas where to start for weights to engage a little sooner. wifes sled, and not gonna be a mountain climber or racer. just trail and some powder play. would like it more usable at lower rpms

 

[snowdad4]

part of the problem could be the roller diameter, springs are cheaper. funny thing on the mtn maxes is they have a high engagement by design. you might try tossing in a yellow/green/yellow in there and see what happens.

my 600 mtn max isnt available right now, but it has the 8DG weights. i played with the rollers and the springs to lower the engagement a bit. not unlike your scenario, its basically the kids sled, just trying to reduce that initial trench when the clutch engages.
