I've done pc5, yosh r77, bmc race, pair mod. Now want to get rid of the entire set valve assembly including the actuator, cables, butterfly etc. I have read the yoshimura instruction on which black/white striped wire to cut on the ecm plug.

Is the actuator and cable ends under the tank and easily accessible? How does the butterfly come out from the header? Any tips before I pull her back apart and do all this?

After dealing with the set valve malfunctions on my last k6 750 and fi lights around 7-10k miles from bad cables etc I want to be proactive and get it all out before anything arises.

Wow this forum has been dead lately lol.

Took her apart today. Set valve cables and actuator are on the left fairing side. Once you remove the fairing you will see a bracket holding a black box with cables running to a actuator. Unbolt the bracket and unplug the harness. Next just remove the cables from the header with 2 10mm wrenches and unbolt the bracket holding the cables at the black box. They will then be loose and ready to fall off.

The butterfly valve in the header defaults to the wide open position once the cables are removed. I did not feel like taking the header off to gut the internals but think this should be fine for a bolt ons street bike.

I also pulled the black/white striped wire on the black plug going into the ecm under the seat. Just yank with a set of needlenose and the whole wire comes out of the plug. Insulate this and plug back in.

Got everything together and no fi lights. Bike lost a few pounds of junk and no worries about future problems.

Great free mod to do along with the pair valve. Bike idles and runs much better.

my bike came with a full Akro so no butterfly but the set servo is still there on the left of the engine as stated, making a noise on ignition turn on, I have ordered a Suzuki " servo buddy" to plug in to the wiring that used to feed the servo to fool the ECU. I can then get rid of the servo itself.

That servo buddy is for those who don't want to pull the wire in the ecm it looks like. I did not use one and had no issues when I deleted everything.

I fitted that servo buddy today took 15 mins works perfectly, removed the servo, quite a bulky thing with the mounting bracket attached.
