I put the new reversible Ski Doo scratchers on my 13 with a 162" X3. I hope that they will help with cooling on the trail. I am also going to put the Ski Z reversible ski ice scratchers/deflectors on it before I ride this weekend. A friend of mine put the Ski Z product on his 156" X3 and rode with an identically equipped sled yesterday. He was running 25 to 30 degrees cooler on the trail compared to the other sled (130 degrees compared to over 150 degrees). That sealed the decision for me. The more forward mounted Ski Doo scratchers and the ski scratchers should solve my trail overheating problem. I will find out this weekend. Other than that problem, the X3 track rocks!
