So, I took my 89 exciter out and lately, it's been having a deceleration vibration. When I accelerate, it seems alright until I start to get around 80 or 90 mph. It doesn't vibrate at this point, it causes a lack of power (dropping slowly from 8000 to 7000 rpm when I should stay around 8000). The sled has a flat sound at this point. once I let off the throttle, the vibration kicks in. I thought maybe the track wasn't lined up right but it was. second guess is that maybe the snow buildup is causing this? The track is out right now and I'm looking for any worn/broken parts to replace. Can't find any. Can anyone help?

This vibration also does this if I hold a throttle position for too long (usually 1/2 throttle or above)
 

turns out, the clutch is worn out, thank you. Next thing, would you, or anybody know where a comet 108c clutch rebuild kit would be able to be found? or if 108 exp rebuilds would fit the 108c? I can find 108 exp rebuilds easily enough but I haven't found any for a 108c.
