clutch issues 05 summit 800 when high alt

[wicked9]

I have a 05 summit 800 144 that does not seem to go over 50 mph in 8-10,000 ft ele. This is on packed trails. I brought it to dealer and had them adjust clutches for this alt. When i drive it out west has plenty of power but can't get speed up over 50-60. rpm are about 8150. its currently clutched for mn and the thing just goes like crazy, over 100 mph on hard pack... i'm stumped and dealer didn't check it for me when i had it re-clutched for mn... possible they had wrong pins in it? any help would be great. thanks guys

I am assuming you HAVE to be changing pin wt. going from MN to 10,000ft?

correct? You should be unloading a bunch of pin weight.

MN I would guess around 20 grams........

10,000ft. elev. riding you are going to be 17 or under on a stocker. I run 15.9grams with a 160/350 spring riding at that elevation. In clicker 4
