Exhaust Servo Eliminator

(111 customer reviews)


All of our exhaust servo eliminators (ESE) are built using the very best engineering practices. They are built first and foremost for performance, robustness and customer satisfaction. We offer a full 10 year warranty on this product! The kit is made from one solid piece of CNC’d Delrin(R) material and potted with marine grade automotive epoxy which yields a 100% sealed enclosure against dirt, grease and moisture.

If you are keeping the stock servo motor on the bike don’t forget to add a blank mating connector with dummy rubber plugs to protect the open floating connector dry and dirt/rust free.  *If you are getting an error code that cannot be cleared with the stock hardware. Please do NOT order this item. It will not fix the issue.

Our Exhaust Servo Eliminators/Emulators (ESE) are digitally controlled via a microprocessor and onboard voltage regulator that guarantees not to lose servo position during whatever extreme conditions; Unlike other products that are purely analog.  Manufactured in-house in the USA.

This kit allows for the replacement of the servo actuator assembly as factory installed on all new motorcycles as part of the exhaust system integrated with the ECU (Electronic Control Unit). The unit gets rid of the servo setup thus giving your bike a cleaner look, leaving more room under the seat, saves weight, improves performance and sound. A lot cheaper than a full system aftermarket setup to simply clear any CEL/FI/EXEC error codes!

*If you are getting an error code that cannot be cleared with the stock hardware. Please do NOT order this item. It will not fix the issue. Contact us for more details.

Device is for off-highway or showroom use only.

Simple installation
1. Unplug and remove the factory exhaust valve actuator.
2. Remove cable(s) to the actual valve installed within the exhaust. The valve will default to the open position. Verify before proceeding.
3. Plug the ESE into the factory wiring harness using the stock connector to secure. Use the optional blank connector with dummy rubber seals to cap off the unused connector on motor side.
4. Turn on your ignition and verify your Check Engine Light (CEL) message is off.

Your motorcycle’s ECU will never know if it is talking to the stock servo motor assembly or if it is talking to our 0.7oz (20 grams) eliminator!

  1. Dave to the Second Power

    For ZX636R WORKS PERFECT! This little TINY plug works like a charm. have had it plugged into my 2006 ZX636R with custom exhaust and no FI light. have ran at all speeds, easy and hard, and no issues. ALSO, the man behind this company is super easy and nice to deal with, beats the servo buddy price, and is willing to go the extra mile for great customer service. I WILL order other product from this guy again! Did i mention the fast shipping?! THANKS VIZI-TECH!

    Worth while bit of kit! This is a top buy not only does it release the beutifull full sound of the engine but used alongside a quick action throttle it gives a more predictable power delivery as well as saving weight this is tiny and so so simple to install. what more do you want, best purchase i have made in a long time.
