Is it an early build F6 or late build? One will have set screw weights and one will not.

Ottawacats - your sled is modded and long tracked so how is your clutch set up applicable?

Well mine was stock with 65gram and yellow/white primary. Green secondary, sorry cant recall helix. I have been running the same clutch kit that I listed above even before the mods. My RPM's have been spot on at 7850.

okay if you want high engagement. may be good in wet heavy snow or off trail deep snow .hardpack may turn to many rpm on top. try it if you have it. i found best setup was 78-7900 out of hole and climb to 8-8100 on long pulls. each sled will be different as will riders preference.i like lower engagement and better mileage with strong mid pull and the setup i used worked good all around for me.could it have been better in certain areas?yes but any clutching is a compromise.
