scroll down the page a page or so to Suzuki (hayabusa) and read the flasher install instructions..(jjmetheny @ Apr. 08 2007,06:01) You don't need to go back to the stock flasher. The one that you added will work with stock or aftermarket signals.
cause here's what it says...
"1. Using a flat head screw driver, carefully push
these two pins (Circled in photo) out from the
plastic housing.
2. Make sure the copper pins are still connected to
the wires as they will be needed to connect to
new flasher.
3. Plug the factory flasher back into the socket as it
is still needed for other functions
4. Connect the light blue wire to the black (wire)
pin inside new flasher connector
5. Connect the brown wire to the yellow
(wire) pin inside the new flasher connector
6. Switch the red and black wires on the flasher unit.
7. Secure new flasher in a secure location.
8. Note: You will now have two flashers.
