I just got done with a full weekend of sledding in Idaho near Bear Lake. Before the ride I changed out the stock 17.5 pilot and put in #20's. What a huge difference that made! My sled has always had a slight stumble right off the bottom from between 1500 rpm's to about 4000. I read a lot of threads about this and fiddled with the fuel screws and it didn't fix it. I bought some #20 pilots and threw them in and now BAM right off the bottom 0-1/3 throttle there is no stumble
. (Read about the install a few posts down)
Next thing I did was got my S8X clutch kit from Dynamo-joe installed. Piece of cake to install (except for the helix aligning those darn splines is a bit of a pain). I spent about 2 hours scrubbing the clutches clean before the intall of the new parts. I put in 17.5 grams of weight in the pins and left my clickers on 3 (I run around 5000-10000 ft). The kit worked awesome. I held back on ordering this kit for over a year
man I should have got it wayyyyyy sooner. This kit flat out rocks! The engagement is at about 4200 which is about what my stock spring did. The kit makes the power come on a lot quicker, you really notice it on a trail. In the deep pow the sled keeps the power right there when you need it. I did notice that my sled would pull about 8250 rpm's then come back down to 8000 on clicker 3. I changed to clicker 2 but my sled would only pull about 7600 RPM's in the deep stuff so I went back to 3. Now my sled is a climbing monster!
I pulled the top highmark on every hill we came to. This kit rocks on hills that have kickers in the middle of the climb, before the S8X kit if I was pulling a hill and hit a kicker the rpm's would drop to about 7400 and stay there, which would make me loose track speed and make me pull out of the climb. Now with the S8X when I hit a kicker on a climb the rpm's will tach right back up to 8000 and keep the track speed. I am thinking of running the 18.3 pins and raising the clicker to 4, to see if it will top out at 8100 and fall to 7950.
The other part of this kit that made me hesitate for a long time was that I was afraid that it was going to make it a bear to handle in the trees????? I was dead wrong. Now it is even easier to ride in the trees because the power is there all the time. I really like to crawl through thick trees and make crazy lines, the stock set-up is pretty good for this, but the S8X kit is a great improvement. It still has a great slow crawl speed for creeping through trees, but now the power is there quicker if you need to hammer it to get out of something!
I love to have my skis floating high in the air and this kit definatly helps with that, just hit a small bump and pin it and HELLO the skis are high in the air
. Definatly worth the money!
The last mod is for weight. The HPS can rocks. It sounds awesome and your drop about 8-10 pounds. They claim 3-4 hp gain by putting this can on......this I am not sure of, if anything it adds to WOT but the weight, bling, and braaaaaap factor are worth the money.
I just recieved my 47 tooth bottom gear from www.hiperf.com and will be installing that this week. Can't wait to try that out!
Moral of the story!!
1. Switch to #20 pilots ($7)
2. Buy the S8X kit TODAY!!! ($260 us)
3. Ditch the suitcase and buy an HPS ($275)
4. Destroy every Cat, poo, yami out there!!!!
