Keep in mind both 9R's and Boosts have factory cluthing that allows them to over-rev, up to 8500 or more. There could be harmonics at these rpm's that the clutch/bolt was not designed for. Maybe that is why some guys have no issues and others do?
You are right, they should not be a wear item. There is no excuse for this issue. That said, we whine and stay home or take preventative measures. I know what I will do.
Yes Shawn they are that good that guys will put up with their issues. That said, Polaris is fixing this issue but the fix has not been released yet. Hopefully by changing the bolt every 600 kms we can stay ahead of it, for now. (about as long as your belts last, only cheaper to replace).

If you don't put it in reverse it should tighten? I assume the mass of the bolt is following the crank and would want to screw in more?
Please clarify.
I have both and the 3.25 definately seems tougher than the 2.75. My 2.75 is showing signs of wear and tear while the 3.25 doesn't. riding both in similar conditions this season.
I had a brand new Polaris with a wobbly lower gear a few years back. It was so bad I was not comfortable leaving it. I highly recommend using Loctite 660 on the splines. The Loctite 660 is for worn shafts and splines. On mine I went a bit farther too. I drilled the axle and retapped larger...
You guys who compare the throttle response of NA sleds to turbos always seem to blame spool time and never discuss the heavy clutch weights that the motor has to swing prior to building boost. Take a NA sled and put turbo weights in it and try to tell me it is just as responsive, I won't agree...
That may be accepted but the law says "clearly visible on the front or back of the vehicle". It is not legal on the side. I told this to the CO who told me to put it on the tunnel and he backed off. I had a tunnel crack from licence plate holes drilled a few years back. Your sticker idea is...
" A different breed of winter adventure" Anyone want to speculate? Doesn't sound like a sled is coming that you are familiar with. Not likely a sled at all. Maybe more like Widescape or something for sled skiing??
You say that but not too many Polaris QD belts are breaking these days. I think they have it figured out. The fact that each belt lists for near $450 is rediculous. Best to sell your QD belt and gears and put the money towards a TKI that can have lower gearing and spare belts are only about $150.
As I remember it, Tom at TKI said the rep for Mitsuboshi was a nice guy and he wanted to support him but when he tested their belts they kept failing and could not bring himself to carrying them. Disclaimer here, someone said they have a better belt now but I do not know.
Unfortunately you are correct about Polaris gaining weight. The hood and 7S gauge added a bunch, also the Series 9 track. I also noticed my Boost did not get the carbon fibre overstructure like my other sled. The turbo is designed about as light as they can go but the stock muffler is a...
