I recently removed the 05 header from my 06 and put the stock header and twin brothers exhaust back on, and after doing so the CEL came on and is now showing a 17/18 code. I looked it up in the service manual and it says 17 is "EXUP servo motor circuit: open or short circuit detected" and 18 is "EXUP servo motor is stuck." But since i have a slip on i don't have and EXUP valve, and i had run this same slip on before with out any peoblems. Anybody have any ideas why i would be getting these codes?

Do you still have the Exup Servo motor on the bike? There's a DIY on making a plug for the exup motor, or you can buy the one that graves sells.
