My Impressions:
Pros:
7/16" diameter runners.
4" of 60° turning carbide.
Cons:
None yet.
Bottom Line.
I put the new carbides on the outside of each ski. Both carbides are 4", so I now have 8" of
carbide on each ski.
You really don't need more length to your carbides, unless your track is studded. Or
unless you want the rear of the machine to skate around the front, which is not good.
If there is
to much carbide in the front, the ski's will turn, and the rear of the machine
goes around the front because the machine does not push in the corner.
It took a little fine tuning with my suspension, but the sled corners better now with my new skegs installed. It is amazing how much you can control the cornering with the addition of 4" of skegs on each ski.
I look at the length of the skeg performing like the center board on a sail boat, not enough center board and you could have adverse handling, too much and you can loose speed & control. Knowing just how much center board to have down is the key to proper turning performance. It appears to work similar with snowmobiles.
Bottom Line is, talk to someone that has prior knowledge about skegs and studs before you start to experiment. Dave at U.P. Cycle & Sport runs a similar sled as I do, but with a studded track. He is very familiar with what skegs, or studs you need to make your sled perform properly. If you don't have a dealer like mine, Woody's has an excellent tech line and can assist you to make the correct choice for your riding style.
