Thought I'd start a new thread since I have a few miles on my 300LX track on my boost now. Ive heard the complaints of the track vibration with this track. Some say the lynx/300lx track windows are smaller causing the extrovert drivers to rub inside the window causing the vibration. My series 8 window measures 38mm wide and the lynx 27mm wide, so I could see that as a problem for some if the Polaris drivers aren't exactly centered in the lynx window. Mine seem to be centered pretty well with a small gap on each side of the driver extrovert in the smaller lynx window. In the first couple rides I had zero vibration, warmer days with pretty deep snow. Really loved the track over the series 8 on the boost. The 3" Lynx with the 23' tune on my 22' boost was way better than I was expecting! Two days ago rode in the afternoon on a very cold, sunny day. Probably lower single digits in pretty good powder. A couple hours into the ride started noticing the track vibration, especially when you'd get on it hard for longer, WOT pulls. After looking everything over we noticed my front heat exchanger was completely iced up. Like a good 1/2 inch coating of solid ice covering the whole thing and the 3" lugs would touch it. With the amount of snow that track moves through the tunnel and zero outlet space up front, we were pretty sure that's where my vibration was coming from. Sounded like a playing card stuck in your bicycle spokes, different than track ratcheting. Let the sled sit and idle until it got to 150 degrees and then shut it off hoping that would help melt the ice off. Had to spend some time chipping at it it get a good share of it out. Once the Ice was gone, no more vibration. Ill add a few pics of the ice situation and the space with the matryx dried out. I measured the front lug to cooler distance on my 23' G3 3" and my 22' boost 3". The G5 almost has double the clearance the matryx does with a 3' track.
