Akrapovic Exhaust / Servo Limiter

Hey folks,

I need somebody who has done an Akra evo full system single can install on an 07-08 GSXR 1000. The install manual shows a servo motor rotation limiter (P-X16) and a new bracket (part P-X44)for the servo motor case. I'm aware of other installations of this exhaust system wherein the servo limiter and new bracket were not installed. Does anybody know why these steps might be skipped on the install?

Below is the URL for the install manual.

Another high quality response from the peanut gallery. Take a look at the instructions.... the servo that drives the butterfly valves from under the tank is where the servo travel limiter goes....

Curt, I'm not sure what your questions is. Page 7, item # 7 seems to be clear to me. Get rid of all the stock cables, the stock wheel & limiter ---- install the new supplied bracket and limiter. This is all done @ the servo motor.

I can only guess the reason this is required is because the travel limiting was done at the valve and since the valve is gone the limit is now done with the new bracket and limiter and obviously must be mounted at the servo motor.

Yes, I agree that's why it WOULD be installed. My question is why would somebody skip that step? It appears to not have been installed on the bike. Weird.

Single exhaust FTMFW IMO...I always hated the huge dual cans the gixxers have. Think a single can would look much better! Cant help you on the install...but you might try PMing Squanto...he knows everything

Correct, Doug. I suspect I have found the answer. Turns out the some of the gixxer guys, particularly those running Yoshi's, remove not only the butterflies but the servo controller as well. The Yoshi instructions have the installer pull pin 5 (the black/white wire) out of the ECU harness.

The link to the pdf Yoshi instructions...

That makes sense - glad you got it figured out. Sounds like you can pull the servo motor and get rid of a little more weight!

Correct... its removed all together... the valve improves backpressure for more torque on the stock system then operates to allow flow.

I personally would remove it too when installing a system.
