Alright, I'm trying to diagnose what this could be, and have no idea. It's been happening for roughly 150 miles now, which was right after my first race. Now, what it's doing. If I open my sled up for more than a second, and let off ( Doesnt seem to happen under 15-20mph either ), I hear a cracking type noise. It's almost like my skis are hitting rocks. But, I know they aren't because I've heard it while riding on snow, that was a solid foot base, with a couple inches of soft snow on top with no chance of rocks. So, what is this noise. I also sometimes hear it after I speed up, then tap my brakes. Im thinking that its either my clutch, or my brakes. What do you guys think. I'll get a video up soon showing the noise.
