My 2010 dragon has a vibration

[kal454]

I have a 2010 dragon 800 switchback, I have a vibration on the clutch side, floor board, it vibrates from 40mph to 60mph and is smooth before and after that speed.
When I let off the throttle the vibration goes away as well, also it seems that I have lost power at 70mph it does not seem to pull like before.
I am just wondering if anyone would have any ideas what to look for. I am new to the sled world and I have no clue where to start.
Thanks

Might need to balance your clutch?

check your compression as well for the power loss.

Could be that your belt is going, change belts and see if that helps...

I did change the belt, but I will look into the clutch, thanks

check the bearing on your jackshaft and drive shaft

Jack shaft bearing. Or worse yet the primary is going to snap off flush with the crank end still in it. I've had this exact vibration before and the clutch broke off.
