I did a fair bit of research on this site to help me setup a 2005 Warrior that I picked up this season, I have gone for 5 rides and I am quite pleased. This is my first 4 stroke, my last sled was an F7.
Some Findings from this site that worked;
-lowering the front end helped the handling alot
-It was -30C and it fired up with full choke, I have a magnetic heater on the oil tank which worked really good.
-I had full strength antifreeze in my sled which I am trying to get to 50/50
-Put in the green holtzman springs (stock airbox) along with 140 jets and 10Ek plugs. It really pulls now, these changes were quite noticeable.
-Hits 10,500 Rpms with stock clutching.
Looking forward to some more riding and tweaking, lots of snow here lately.
