[QUOTE="Ol'89r, post: 1194146, member: 17212"] Yes, the power valve linkage can be off. Unfortunately, the only way that I know of to reset it is to remove the cylinder and look in the exhaust port as you are setting it up. The two transfer port valves should be flush with the transfer port in the open position. You should be able to see the shiny wear marks on the transfer port where the valves ride. Use those marks as a guide as to the open position of the transfer valves. If the sliding rack or the rotating valves are only one notch off, your bike will not run to it's full potential. Also, make sure the transfer and exhaust port valves are clean. If they are coated with carbon they can stick. If you don't have one, it would be a good idea to purchase a service manual. It will explain the proper set up for your power valves. [/QUOTE]
