    If the carbs off another 850 work fine on that bike and dont work right on yours, then its likely not a carb problem. Leaking induction tubes, clogged air cleaner, or retarded timing could cause bogging. It could also be a fuel flow problem, or bad electrical connections.

      Hi :roll: :roll:

      I think it can be a bad sparkplug.
      Had the same problem.
      I had to replace 1 plug with a new one.
      Remove plug boot one at a time.
      Or see if all exos pipes is hot.(mine was not)
      Then swap cold plug with a hot plug to see if problem follows plug.????
