GSXR Fuel Injection Code List -
To read your code you will need to go into Dealer Mode. Don't panic, it's easy. The dealership has a 'special tool' for this but you can easily make your own.
Take off the front seat. Behind the battery you will find a white open ended 6 pin connector (might be 10 pin for k6?).
If it has a cap take it off and as you are looking at it jump the right wires top and bottom
with a paper clip.
Turn the key to the ON position and you will see on your dash a C code where the temp would be.
(or C00 if you have no codes. This is often the case when the SET valve is the problem as the computer resets it if you turn your bike off, otherwise it would be C46)
It should be a 'C' with a number, like one of these >>>
