Just installed mine last night. In my opinion you have to fully remove your gas tank to reach the first cylinder wiring housing. Unbolt the tank under the seat, lift up and prop something under the tank, unhook your gas line and two other wiring connectors, pull tank back towards you and it will release from the front mounts. I'd reccomend that you have close to an empty tank so that it's as light as possible. Once the tanks off you just loosen the air intake and move over to the right. Then its just a matter of cliping the FI2000 into the front & rear cyclinder and your done (other than putting your tank back on). Should take you maybe 30-45 minutes. Piece of cake!!!
