I changed the clutching a little on the wife's sled and now it is keeping the clutches engaged until it gets slowed way down. It use to take the load off the motor almost as soon as you let off the throttle unless you were going really fast. Now it will stay engaged while you are going down hills until you get slowed way down. I'm not complaining, it slows you down way better than trying to run the brakes. I was just curious if this meant the clutching was on or if it is wanting to back shift to fast and I need to run a little lighter spring or steeper helix.
Clutching good or bad?

Not sure it means your clutching is "On". As in perfect.
But if it works for you this way great.
Depending on the sled. Most smaller CC machines or sleds that don't have a lot of bottom end will have stiffer starting rate primary springs. This is to raise the engagement to get them more into the power rather than having a bog.
Question is? Does it bog off the bottom. If not leave it alone. If it does you will need to increase the spring starting spring weight in the primary.
Ie if you now have a 90/290 primary. You might need a 110/290 or a 130/290 to get the R's up on the bottom.

What did you change, (did you put in a shift assist)
I put a straight 40 and sa in the secondary. I also used the plastic adjuster nut and cap off of my m7. It had titanium springs in both clutches so I swapped in a cat yellow primary and a cat orange secondary. I left the primary alone other than the spring change. The bog I got came later in the day when the nose got some snow in it so it was sucking snow in the motor because I took off the factory intake. Frog skins and silicon should fix that problem. The sled by the way is a 09 m1000 153 with slp y-pipe, pipe, super-q can, and bd
