My 21 Khaos 163 with 300km is "clunking" on takeoff from a stand still. My track tension is correct, track alignment is correct, and my belt deflection is set so the main belt just below the nubs is about 3mm above the secondary, tight but does not squeal at idle. The sled runs great but I cringe a little feeling this on takeoff, happens even when I'm super light on the throttle. I thought maybe it's the sound of the driver hitting the window and it may be more pronounced in Polaris than the Doos I'm used to? Probably just a case of too much mechanical empathy, but if this clunk sound (that I can feel right through the bars) raises a red flag for anyone let me know.
