Healtech STV Eliminator STVE-05

Due to emission and noise control regulations secondary throttle valves appeared in motorcycles in the last decade. This secondary butterfly is controlled by the bike’s ECU. For maximum performance and crisp throttle response this secondary system is removed – mainly in drag racing / road racing. However, as soon as you disconnect the secondary throttle valve actuator motor from the bike’s main wiring harness, the FI light will come on on the instrument panel. The STV Eliminator plugs into the bike’s wiring loom directly. With the help of this small unit, you’re able to remove the whole secondary valve assembly with the actuator motor, the butterfly valve plates and the rod/shaft too. Get the job done properly with this easy fix!

Note: After installation, we recommend having the AFR (air-fuel ratio) of the engine checked by a dyno center and adjust if necessary.
