872
it is expensive when compared to the cost of premium membership. Other than that people seem to like it.

okay highvoltsledhead give me your update,was it worth the 1200 km of driven back and forth in 2 days?and going with out sleep and raping all your buddies of every stock part you could find?Lol just to go on this ride with your 872 I'm wishen I was with ya.I'm betting your shoulder will be sore and your face will hurt from smiling,but remember BREAKIN period buddy.You are by far the most dedicated sledder I know.

Any updates
Okay...here we go. Breakin period.....hmmmmm.....I was once told to break them in like you ride them....for me , thats wfo all the time !!! Dont worry,Dave, I didnt do that here....lol !!!
Got almost 200 hundred miles on it now and it is still gaining power. Clutching is currently set like this:
160-320 spring with 18.8 grams on stock arms with oversize high torque rollers with 441 ramps. Started out on clicker 1 pulling 7500rpm consistently, now on clicker 5 pulling 8000 consistently. Need to get it dialed at clicker 3. Will lower the weight and go from there. Secondary has a stock spring with a QR11 helix (dont know what the angle is on this helix) and high torque rollers.
I am pulling all of my primary with a thin black line about 1/8 of inch from top of sheave. Backshift and upshift seem good, track speed is bx 40 -50 mph and over 60 mph on the hardpack. Stock gearing on an 09 summit x 163 with stock drivers. Runing 25% vp 112 and seeing 1170-1200 on egts on a long climb and 900-1150 on a bumpy trail, depending on how long I am in the mid range.
The sled has room for improvement on the clutchng but it flat out freakin rips !! I have never felt this kind of smooth acceleration and torque. There were several occasions while climbing when I would hit a packed trail and damn near have the sled rip out from underneath me....You need to hang on with this beast or you will lose it.
I am very impressed !!! 4 days of breakin and long climbs and trails and not a hitch. Well done Dave !!! Cant wait to try the new head.:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap:face-icon-small-hap

Thanks Dave. Got almost 300 miles on it now and it needs to be re-clutched. I will call you later today to discuss some things.
Any updates on the 872? Anyone?

Here is a video that Mike Suter from Star Valley Ski-doo made last weekend while we were working on some clutching for Luke Rainey's 872 mod.
The sled rips!
