My tourer had torque, it could almost be shifted to top at walking pace. I have replaced the spark plugs with new, the smaller diameter thread type with an adapter spacer. It is correctly timed and correctly gapped but lost much of that torque. A shift on the advance/retard lever makes no difference. I notice the gap in the old plugs is much bigger than the new.
Question. Would this gap be the cause of reduced torque.
Throw the old plugs back in and see if the power comes back.
