riding elevation: 6-10,00 feet

riding style: boondocking mostly, sometimes I'll point it up a hilll

aftermarket head: no

exhaust: SLP y-pipe, exhaust pipe, can

intake: BDX air box

spark plugs: NGK

fuel: 93 .... SAY NO TO ETHANOL!!!!

oil: Arctic Cat APV synthetic

fuel controller: nope

clutching: SLP 40/60 secondary helix, MTX 75(?) gm weights in the primary (Thanks to Valley Marine of Yakima for doing the primary, other dealerships in the NW part of Washington were unwilling to do so... suckers)

drive belt: AC

gearing: stock

top track speed: _?______

peak rpm: _~ 8200??______

dyno numbers: _??______

the best mod i've done so far: _I actually think the BDX Two-wheel idler kit is one of the best mods I've done. After doing that simple mod, I was able to lay the sled over so much easier and I feel like the turning radius improved. Also maybe I would say BOSS seat, altough I was pissed the AC dealer in Pinedale wouldn't warranty it because they said it was because I was wearing "snowboard boots"... what a crock of you know what. That being said, those first M8s had a horrible seat design, my firend's 2010 is way better and Polaris still has the best stock seat on a mountain sled. I also really like the frogskinz vent covers, and the Side panel vent kits, definetly improved air flow.______

a mod or part that gave me some problems, and how i fixed it: _Skid Plate, I can't keep that thing on, can't find the right size rivets (too short on the grip) in the Sun Valley area, need to grab some from the dealer sometime when I'm near one.____

next mods i plan to add: _I think I'm good, maybe V-force 3 reeds______

links to other threads regarding my parts: _____

additional info: __Valley Marine in Yakima, WA.. you guys are good. I've lived in Idaho, Western Wyoming, and Washington for all my life in those three states, and hands down Valley Marine is the best I've been too. Mt. Baker Motorsports is a close second, but I was bummed when they wouldn't do my spider for the MTX weights and then i broke down when it went to crap, still good service though, probably the best of the 5-6 I've been too in WA, ID, and WY_______
