Secondary Butterfly removal/replacement?

[BENDO]

I have an 06 R1, and I'm curious about this...

1-Are the secondaries, the higher set?

2-Removing them would require a remap ?

3-Does removing them just let an uninterrupted flow of air to the primaries?

4-I thought the secondary butterflies, didn't open till after 7,000rpm?

5-Doesen't this just leave the primaries to do all the work? why is that better?

6-Does this just show that secondaries are just a emissions flat spot/ midrange repair thing?

7-I've read of replacing the butterflies with smaller ones for a more progressive effect, why?

8-Would there be a loss at another part of the rev range?

9-Would it make a noticeable difference with 175hp/184kg, carbon rims, +3T on the rear, and a 1/5th turn throttle?

-Am I an idiot? (you don't have to answer that one!)

yes

yes

yes

yes but depends on throttle position ( IIRC )

yes , because you might get another couple of horses at the top end ( even if you lose its sweet low down running )

'ish on the midrange thing , if you've got big injector bodies you've got to keep the gas speed up somehow

dunno

look in the mirror

you may be able to alter when they open with one of these

I went to see 'em a couple of years back and they said at the time that on the fly by wire models you could alter the response , it may be worth an e-mail to see if it's possible , keep us informed

Thanks Ron. By the gist of your replies, I don't think it's a particularly helpful mod. I like my midrange, and fine throttle response. I was just curious for information. Mine's the last direct cable controlled throttle model.
