I have an 09 with SLP pipe and cold air kit. I am using stock gearing 19/41, Ron's weights (yes they work awesome Ron!!) around 66 grams I think, he can help with that. SLP Blue/Pink primary spring, Carl's helix, stock black/purple sec. spring, 2 delrin washers in secondary. Make sure your primary belt side clearance is set. Most don't do it, it's worth it. I have mine at .015".
I ride from 2500 at the truck to 8K, generally want the sled to work best at 6-8K the rest I can work with. I ride fresh powder as much as possible.
RESULTS - This is the best running sled I have ever ridden. I have been mountain riding for 15+ years. It is crisp and snappy all through the range and has tons of legs on the top end. Runs 8200ish all day. Great on fuel, clutches are cool, belt looks great, I have lots of venting.
Just for FYI on new update, I used Polaris Blue in the first tank, premixed 1/2 qt. of Blue in the first tank of 91 premium. I unplugged the fuel wires for break-in(still unplugged at 230 miles). Warmed up sled to 110 degrees then shut it off, let it heat soak while I gear up. Then rode it, easy for the first couple miles of the trail, normal the rest of the way, 15K or so, always varying the throttle (I always ride this way, never hold the throttle steady for long periods). Once I got to the alpine I rode it like I normally do, lots of varied throttle, a couple decent length pulls by mid day for sure, we had 1 1/2 ft of fresh.
Sled works amazingly well, I would not hesitate to run this combo, you will smile all day.
Starts cold, starts warm, runs clean, seems as strong or stronger than my 900 and I had a very strong running 900 as a comparison.
If you don't have the SLP stuff, just let Ron know on the weights, he may or may not take some weight out but should be very close, everything else is fine.
Enjoy!!
