      Well the mechanic did a bust up job on your bike, or the running in was not done properly. I suggest you get the rings checked again, and get the carburetor re tuned for more fuel to the engine. The smoke is due to engine oil burning with the petrol in the cylinder.

        ^^+1..get the piston rings checked for proper seating as well as tune the carb for optimum air fuel mixture.

        A motorcycle functions entirely in accordance with the laws of reason, and a study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself.

          This is the reason. I think rings are already busted, better to take your engine to a Auth Service Station for complete check up and damage control.

            With a new piston you should have run it rich. Get it checked immediately befor more damage is done
