All-
I finally had a chance to get my 04 Busa out this morning to ride to work. As soon as she fired up, the RED FI light indication came on and stayed lit. The bike idle was terrible, but stayed running, and the throttle response was rough, and did not seem to clean out no matter what RPM.
I called a shop prior to getting the code, they immediately suggested a fouled plug. Sounds logical, but I cannot figure out how the plug would've fouled when it started right up with no issues.
I came how, of course checked the forum, and found an old post from Charlesbusa with the "paper clip" trick, and a list of error codes. Mine registered as a -C27. According to Charles list, this is:
Ignition Signal - Crankshaft position sensor ( Pickup Coil) Signal is produced but the signal from Ignition coil is interrupted continuous by two times or more. In this case, code C24, C25, C26, C27 is indicated.
Ignition Coil, Wiring/Coupler Connection, Power Supply from the battery.
I guess my question is, have any of you had this issue? SInce no mechanical changes have been made this year, I find it difficult to blame a wiring connection. Would a fouled plug throw this code confusing the weak spark as a coil issue?
Any help would be greatly appreciated. I cannot have my bike down. I work too much to not ride it every chance I get. My batt is going on five years old, but it starts the bike fine every shot.
Thanks all-
