Well, i finally got my Yamaha 1200 put back together and may have a problem. I rebuilt the top end and carbs. The engine fires right up and sounds good, however i noticed that the power valves are not moving. Here's my question. Should the power valves be moving at idle or only when under a load? This may be a dumb question but i just don't know much about these valves. Any help will be greatly appreciated.
