1. Installation tip
L1+ GSXR750 ignition barrel security bolts are size 40 security torx screws. They sell the bits to remove them at Ace as a kit labeled Best Way Tools® 33 Piece Extractor Security Bit Set (45002). No need to drill out the bolts.
Follow the instructions, lift the tank, remove the airbox and the connectors are right there. Figuring out the tabs to release the connectors always drives me bonkers. Other than that it was a piece of cake.
Plug the pair valves while you are in there with some 1/2" vacuum caps from the auto store.
