CNC'd case. Plus epoxy makes this the best quality servo eliminator you can get for your Yamaha. 100% water/grease/dirt proof.

YAMAHA exhaust valve servo eliminator aka "YAM.EE" is a digital solid-state electronic device that is designed and manufactured 100% right here in the US of A by vizi-tec! This product comes with a factory warranty of 10 years! This device allows for the replacement of the servo actuator assembly as factory installed on some Yamaha motorcycles as part of the exhaust system integrated with the ECU (Electronic Control Unit). The unit allows you to get rid of the servo setup giving your bike a cleaner look, leaving more room under the seat, saving weight, improve performance and sound. It also allows removal of the servo cables to the exhaust butterfly valve that have been known to fail or cause problems. A lot cheaper than having it serviced by the dealer or constantly replacing the mechanical motor assembly!


(ie: No CEL error messages). Device is for off-highway use.

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.
3. Use the provided tie wraps or optional double-sided tape/velco to secure the YAM.EE.
4. Plug the YAM.EE into the factory wiring harness using the stock connector.
5. Turn on your ignition and verify your Check Engine Light (FI) message is off. Done!

Unlike the other less robust plastic and analog products out there, the YAM.EE is controlled by a micro-processor that guarantees a constant servo position regardless of voltage fluctuation. The physical device is machined CNC from a single block and epoxied using automotive/marine grade products which makes this the best quality servo eliminator you can get for your Yamaha. 100% water/grease/dirt proof. And because of this we offer a 10 year warranty!

Unit body: H = 8mm (0.315 inches) L = 24mm (0.945 inches) W = 35mm (1.378 inches) Mass = 20 grams (0.7 ounces)

    Excellent servo exup bypass

    Good work, no more 17 and 18 codes in the ECU. Much better than others that only have a resistance and condensor that not work properly.
    I recommended this one.
