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.
Quick and simple to use
Just disconnect the actuator motor from the main wiring harness. Plug in
the STV Eliminator and the unit will act as the actuator motor would
still be in place. No splicing or soldering required and the bike’s
wiring harness remains intact. It can’t get any easier than this!
