I too just bought a 16 pro s switchback. Have about 350 miles on it, and so far I like it. Only things I've added are the skins bag that goes over the rear X arm on the suspension for storage (great addition, can bring oil,hat, extra gloves and a hoodie) and took the 3-6 inch adjustable risers off my iq shift and put them on this. All stock cables. Made for nice improvements, especially the risers. I'm 6'2" and when I first stood on the sled with stock bars, it was by far the most comfortable sled I've ridden standing up in stock form, almost didn't put them on... but now that I did I'm glad I did! Huge difference and it plays into the other posts on here about weight transfer..
I could not get this thing to transfer weight to save my life in stock form. Incredibly planted on the front skis and literally handles like it's on rails...and then some. And if I was the guy in a group of buddies racing the trails non stop at 85mph plus it would be a winner everytime..but I'm not. I ride with the fiancée 90 %of the time and while average speed might not always be super high I love to wheelie and play in everything I see. Only problem is its so anchored on the front skis it barely even pulls them off the ground! And I will admit, I'm not ready to blame the sled, yet. I have ridden sleds pretty hard for a while now BUT, never had even close to this much suspension adjustments available. I just set the rear spring as stiff as it goes and rode it in the past.
So with this thing, when guys say add preload to the front track shock, are you doing that with clickers or by turning the actual coil spring to change the compressed height? I have a buddy with a 14' indy 800 that says it's so light and wild in the skis he has to throw himself over the front to get the carbide to dig, and then it will inside ski lift and wheelie at any flick of the throttle in the corners. ..while I don't want it that extreme, I do want some kind of compromise so I can feel a little on the wild side! My switchback is as wild around corners as a train on tracks...literally. but then you go to cross a road and feel like your going to do doughnuts in place pivoting on the inside ski because the track has so little pressure on it, I've literally had to bounce on it to get it to cross a road! No joke it was just spinning!
Long story longer I love the sled don't take it wrong, I just feel my novice abilities in suspension tweaking are holding me back. I'll give up the ability to corner dead flat at 80 mph to gain the ability to be able to pull the skis without looking like your nephew trying to do it on his indy 340 lite... any suggestions?
