I have a FI light on itermittently. Sometimes its on my entire ride, sometimes on and off, sometimes not at all. I did dealer mode and code 63 is the only one that popped up. Its related to the exhaust servo. Doing some research on this I find alot of problems related to aftermarket exhaust. I haven't really found a fix for this, mine is stock exhaust.

I was wondering if anyone knew the cause of this code. I looked in the manual and saw there was an alignment for the servo. I did just teardown and rebuild most of the bike. I was thinking the alignment of the servo cables and everything might be the problem, maybe my exhaust valve is sticky? Anyone have a good place to start fixing this?

Please dont say aftermarket exhaust and servo buddy.. I think this thing is plenty potent, and I like the drivability, and its plenty powerful already without making tons of noise.

Thanks in advance. Heres a pic of what Im working with...

I suggest releasing the cables to the exhaust valve and make sure the valve is free to open and close and that the cables are also free to move in and out.

After that the only thing left is the servo motor itself. Check to see if it moves when you move your key to ON and power the bike. If not then replace the servo motor. I would also check the electrical connections to the servo.

I hope this helps

I had exactly the same issue, it is the valve flap... if not it could be the servo exactly as the above advice... when you turn to ignition does it make a sound? I had my mechanic look at it he adjusted the valve opening to ensure the flap was opening to take in air and that solved the issue.

thanks for the replies! I took it apart to check that the valve was moving freely. Looks good and the servo moves also. I tightened the cables and made sure that everything looked aligned. I guess I will see tomorrow morning how it works. I hope that it was just something out of alignment.

Looks like it worked.

I think the cables and everything were out of alignment, from dissasembling/ reassembling the rear end. There is a section in the fsm that outlines the alinment of the cable tubes where they attach to the exhaust and alignment of the pulley. After everything was aligned I just tightened the cables up and its been good.
