the exhaust servo is a valve on an actuator that is controlled by the ECU. Its function is to supposed create addition backpressure at lower RPMs by slightly closing to restrict exhaust flow, opening in the midrange RPMs to allow full exhaust flow for the most power, and then close in the upper RPMs to reduce noise for the EPA and those other folks who dont like loud motorcycles. On a Gen 1, the servo is located in the header.

To disable the servo you can do a few things. 1, remove the exhaust valve entirely by installing a full exhaust system. 2, unhooking the cables that run to the valve so the servo cannot move it. 3 (an additional step to 2), unclip the servo motor and remove that and the cables that run to the exhaust valve.

This mod is designed to create the circuit that is completed by the servo motor so that the ECU does not tell the gauge cluster to flash an FI Error, as removing the servo motor will. Hells made it very cheap instead of having to buy one for 4 times what you would spend on this. It is however, slightly more expensive than the black electrical tape mod. The nice part is that this mod will let you get an FI light when something is actually wrong with the bike and not just for the servo so youd never know.

The Black electrical tape mod Good one.
Thank you for explaining that for me bro.

As of yet for the Gen 4 :headshake You will have to have that done when you flash the ECU.
Trust me, If I can figure it out for the Gen 4, I will post it up.

So far I have one for the ZX10R's Gen 1-3, Z1000's & ZX6R's.

Anyone remember that one from the 1970's ?

Glad it helped you out bro.
Which bike did you do it to?
I was looking at your list of bikes.
Was it the Z1000 or a ZX10R? And what year.

i have seen write ups before, but hardly any of them provide good links to source the items, your thread really helped a lot especially for some one like me who has very limited electrical knowledge!
