If it is anything like the ZX6R, it can and probably will at some point. All you need to do is get one of this: http://www.servobuddy.com/Kawasaki-Servo-Buddy_p_8.html
And then you can get rid of the whole thing (cables, servo, etc) and it will never throw any code.
It looks like the servo is attached to the boom box, so you will only need to remove if you get a link pipe also..a simple slip on would require no mod to servo..
A couple of mixed messages I think. If you just replace the slip-on can, the cat box underneath (called the Collector) stays in place, you get a slightly different sound with luck and don't touch the servo. Minor performance changes but essentially cosmetic - deliberately designed for Bling addicts who want to look cool and it's not hard to improve on the stock can's appearance.
If you fit the link pipe, you need to disconnect the servo cables at the servo motor but do not remove motor or the electrical connector to it. You also need to unscrew the footpeg and footguard to release the cables and partially remove the cowling. You then disconnect the Collector at the headers connection and the lambda sensor and unscrew the Collector hanging bracket. This way, you remove the Collector with the cables still attached and replace with the link pipe as per maker's instructions.
You now need either the servo buddy or the PC. A PC then needs to then be mapped on a dyno. Not sure about the servobuddy. The local cost for a PC plus dyno work until it's right is around $800 at a reputable shop - like Ron at Flywheels in Sydney. I'm sure there are ways to buy the PC overseas and negotiate mates rates at the dyno that reduce this somewhat.
Although he isnt a sponsor, he is a member here and since we dont have any suitable sponsors locally I can recommend Brad @ Enhanced automotive, Bremen Dr Salisbury South 8250 2233, great advice and will do all the tuning for you, yes he does cars as his core business but you will find he is quite the sportsbike tuner as well as a respected racer.
Yeah its all done now! He was just after bling and a little but more noise! Only reason I really asked was because i couldn't see the bike and was curious as to what needed to be done...
