I changed spark plugs and now get FI warning light and error message on display screen. Also changed to K/N air filter. Bike runs real fast and smooth now which is great but when key is switched to start position throttle body butter flys quiver continuously and sends the code fault. Any ideas on what is failing and anybody know of a free phone downloadable service manual for this bike? I´ve ordered a hard copy but not here yet. Thanks in advance for the help. P.
