What you're suggesting, companies likes K&N (and other R&D places) as well as smog places would have to remove your cat to get an accurate reading.
I know a guy that does dyno tunes and does a great job, and I know he doesn't do anything. As well as the guys that tow their dyno to the track and tune bikes up at the track for whoever wants it done.
Don't get me wrong, my '06 1krr could still be tuned well. But if I didn't either remove the pair system or block it before I had it dynoed, then the software would show the bike running leaner than it actually was.
This is due to the pair system blowing extra air into the exhaust to help burn any unburned fuel for emission reasons. I'm trying to find out if the 'r1 has anything like this. I also had an egcv (exhaust gas control valve) on the RR and it seems like it was the same thing as the exup on the r1.
What's with the AIS block off plates? This seems like the mod that is similar to blocking the honda PAIR system. I'm not sure if I fully understand what the AIS does though?
Does the R1 have a flapper door in front of the intake system? On the honda there was also a mod to keep it open at all times since it stay shut at lower rpm's forcing the engine to breath through a small tube. You could feel a little more power down low after doing the mod. If you know the answer to any of these questions I'd really like to learn more about this bike since I'll be purchasing one once it gets to the dealer.
