ZX14 throttle bodies

[13]

There is a guy from around my area that got him a 14, sneaky SOB. Anyway he's telling all kinds of thngs about his bike.
Told a few guys that his bike had a bog off the start so he sent the throttle bodies off to get some work to clear up this problem. I have never heard of this, just wondering if anybody knows much about those things.

they have butterflies that open up after a certain rpm to keep power down in the lower rpm's.

is it like the secondarys on a 1000.......................

closest thing i can liken it to is the 99 mustang cobra,  they are actual blades that restrict airflow until a certain RPM.

It's true.

Same thing with my FZ1...  All you got to do is remove the second (top) set of flies since they do not open till 6000rpm.  On a 14 with the bike tuned it is worth 20rwhp from 4000 to 6000 rpm...

...and from what I've read here and there, drivability goes to absolute shit when you do that...  Even Brock had a writeup about trying that on his ZX14 on his site somewhere.

I believe if you read Brocks write up - his maps cured the problem..

Drivability stays the same with the flies out, Brock changed his write up to reflect that. Have had mine out for 3500 miles.
