Before going to the dyno..

[7777r1]

I will be purchasing a 2007 R1 once my local dealer gets them in. On my 2006 1000rr I had to gut the cat and block the pair valves before taking it to the dyno to get it custom mapped because the air/fuel ratio could not be properly read without these two things being done.

What will I need to mod/remove on the '07 R1 in order to get a correct reading on the dyno? I think I read somewhere that there is two cats on the bike. I guess I'll have to remove them? I live in california so there will probably be about 10 cat converters on my bike, lol!

No but seriously since I'm new to the world of R1's I was just wondering if there is anything like a pair valve mod, or flapper mod that will need to be done? Or maybe an o2 sensor eliminator that I will need to get before getting a custom map?

you will have an ais to plug you should be able to jsut pinch the vacume tube for your dyno purposes it will lead to the top ove the valve cover with a servo in it

What's an ais? Does anyone have a write up or pictures showing the location of this vacuum tube? Or how to properly block it?

It looks to me like there is some sort of 02 sensor near the cat on the '07. Is that what it is? Will the cat need gutted before getting the bike mapped?

You should be able to throw it on the dyno and get accurate readings, unless they have a cheesy dyno.

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.
