What are the weights of the two different pins used in the 06 Gade 800X, one with the 1.25 track, and the other the 1.75? The 1.25 uses #417222594, the 1.75 417004308. A friend of mine ordered his with the 1.75, the dealer screwed up and ordered the 1.25. They changed the track to the 1.75, but did not change the pins, or the gearing from the 23/43. He cannot keep a belt on the sled. I told him to gear to 21/45. How does this sound? Rides on and off trail, 1600-2200ft. elevation, occasional trip to the mountains. How about leaning the mains 1-2 sizes?
