Hey there everyone.

I just bought myself the new 2010 Kawasaki Z1000!! STOKED!!!

When I bought the bike, the first thing I ordered was some slip-on pipes. I got the M4 GP style slip-ons. I figured it was going to be an easy, straightforward installation - take off the OEM mufflers, replace with the aftermarket slip-ons.

However, Ive noticed that the OEM mufflers have an exhaust valve located in the muffler on the right side of the bike. The aftermarket slip-ons do not have a mount for this portion of the exhaust system, so my question is: What do you do with the OEM exhaust valve?? Just leave it hanging there? Completely remove it (if that can even be done??) Is that going to affect the FI system??

I asked at the dealer where I bought it, and of course they recommend that you buy and install a Power Commander...is that really necessary for slip-ons? (Ive only ever had a power commander for full systems, not slip-ons...)


Any insight is greatly appreciated.

Hmm, im not sure yet. I know if you unplug it you will likely get a FI light turning on. They might be correct with the PC.

I will dig around and see what I can come up with. Could be something similar to Honda's. My CBR had the same thing. I think there is a jumper you can plug into its place.

Sorry im not as helpful... but I will see what I can come up with.

I have an 08 and I'm buying a new full system this week. The new pipes won't have the valve (it's BS anyway-I've seen it written up several places that without it there is zero loss in low-rpm power) But you don't want it swinging around under there. Follow the cables back to the servo motor and take them off (like the two throttle cables attach to the throttle sleeve). I'm getting an Akrapovic system and they cover this in the instructions. Just removing the cables from the servo (located under the seat on the left side under a plastic cover on my bike) doesn't affect the FI system at all, supposedly. If you want to completely remove this servo (to shave like, 9 ounces off) you need a little piece that plugs into the wiring connector there,to give it whatever feedback it usually gets from the original servo. Ivan's performance sells them for about $100, but like I said, just remove the cables and leave the servo alone. And get a PC V.

Advice appreciated. But is the Power Commander really necessary?!?! At $400, I cant really afford one after buying a new bike AND slip-on pipes... Now, for a full system, sure I would need a PC-V - but for slip-ons?? Whats your take?
