Hi,
picture is worth a1K of words . Two strokes have power valves FZR 's do not . are you refering to a gizmo attached to the exhaust pipe that Yamaha call EXUP ?

Its probably been unplugged as normally it powers up when u turn on the bike.

plug it all in and see if it turns when u power on.

Its called a "servo motor" :grinnod:

"14" on here...
