I'm thinking that if the computer is trying to compensate by leaning out the fuel when you remove the ais
then it would be a rather simple matter to fool the computer into thinking the exhaust is too lean and compensate the other way and go rich.
There are a couple ways to go about doing that without spending over 200 big ones for the plug-in thingamajiggers they sell.
As for unplugging and removing the ais, it didn't make a detectable difference in how the bike ran and I've never gotten a fault light.
I removed the ais, opened up the air intake with a K&N air cleaner and none of this made any difference that I could detect in how the bike ran. I did one operation at a time.
What made a difference was when I removed the factory mufflers and those are downstream for the o2's. When I opened up the pipes I lost power across the band which is to be expected with open pipes.
What I'm saying is, the exhaust affects the bike more than any thing else.
The Cobra slip on's weren't bad, but they didn't give the performance the bike is capable or the sound I wanted either.
It was fairly zippy the way it came from the showroom floor, but it was still not the bike it ought to be, running the engine it had on it.
