I posted this on the SXR page and here as well in hopes of getting a few view points......
O.K., so I got out for the first time today in Northern MI! About 6-8" in the Higgins Lake area, not bad for early December...This was my first ride on my sled with the following mods:
Carbon Tech reeds with Maxx Perf spacers
Head gasket with metal layer removed
Jetting: Main1 (142.5), Mains 2/3 (141.3), needle at 2.5 and air screws at 1 3/4 - Jetting spes as recommended by maxx perf
Stock Silencer bored
Camoplast Ice Claw Track
Stock clutch setup
At first it wet foouled the plugs right off idle, so I readjusted air/fuel screw down to 1 1/4, and put in new plugs, which cleaned the low end right up. Once that was done, I took it for a ride. Great throttle response and noticable increase in power! However it's now revving out at about 9,000. Seems a little high as it used to be around 8,200-8,400 with the stock setup. Track seems good (was running the stock track with 144 woody's), maybe a little looseer than before but good.
My question is; is the 9,000 too high and if so, what should I do to get it back in the sweet spot? Also what about the jetting? Does this sound on target? Plugs looked good after about 30 miles, maybe a little on the lean side but I think it's hard to tell with brand new plugs. It definately rips.
Never messed with the clutch before. Are there any special tools needed to make adjustments? Any help is appreciated.

You will need a primary clutch puller, about $30.00. Your primary should be retuned to reduce RPMs. You will need to add weight (riviets) to your weights. I used Turks recommendation of 4.5 grams in the heel and 3.1 gr. in the tip. I also changed the helix to a 51/43 and used the stock springs and weights.
Check the snowmobile tech area for other good setups.

You don't need a puller however as this can be done right on the sled.

Good to hear you've had the beast out, buddy!
You need to add appromately 1 gram for every 100 rpm to your primary weights to bring it down. You might as well try the new rivets, although you'll find drilling out the old ones is a treat
Depending on hat kind of riding you do, you can go to a different weight with a profile to suit you, I love the low and midrange of the 8ab's or 8ca's. AB's would allow you more tuning room, but if you're thinking of further mods, the 8ca's would accomodate. They're the same profile, but the ca's are heavier.
Check out the clutch tuning page for some idears.
It's a good sign that you're mods are paying off, but you're throwing away a ton of power by overrevving. I've been there! Your sled has probably slowed down on top end
hehe
But...you can easily remove the weights on the sled, no puller needed. I do it on the trail! Pull the cover off the clutch with a small wrench, 8mm I think, hen you'll need an allen to loosen the studs on the rollers, then use that 8mm to pull the rollers, then the weights. Keep the washers organized, there's 2 sizes. Put it all back together and take good notes on the changes. Have fun!
