Things I have discovered since taking the intake flap out:

I did not change anything about the ecu and I left the mechanism that closed the flap connected to the system, it just doesn't close anything anymore. Stock exhaust with the exhaust flap disconnected too.
1) The shift light I had set at 13200 is no longer valid, bikes pulls hard all the way to rev limit with no decrease in power.
2) Idle went up about 100rpm.
3) Noted rise in dB level. My house says they can here me leave and come back clear as day now and I can definitely hear more from the engine from normal riding.
4) On/Off throttle transition significantly smoother.
5) TC1 does not catch power wheelies anymore and I was not expecting that. If I catch the wheelie myself and bring it back down to around 1ft then roll on it handles it from there but there is no more catch at around 2ft then it brings it back down for me.
6) TC2 behaves like TC1 used to with power wheelies.
7) TC3 Behaves like TC2 used to with power wheelies.
(Did not test TC4 or TC5 for power wheelies because I never tested those at stock so have no way to confirm a change)

The power wheelies and On/Off transition I absolutely was not expecting so I wasn't looking for them, definitely noticed though.

I don't see the connection to the TC. I have a GEN5 and removed the intake flap and all of the associated hoses and valve and it didn't change my TC or wheelie behavior at all. You didn't disconnect the vacuum line and not cap it did you? Even still I can't see it effecting TC.

I can't see the flapper removal causing such an increase in hp that it overwhelms the tc.. I've been wrong before though

More cowbell

I expected nothing besides more up top power but it really did change quite a lot for me also I don't think it is too much power, I think the flap played some role in managing certain aspects of TC. It being gone without telling the system it is gone might mean the system is not able to function completely.

Which is what I read from more than one source but it doesn't seem to be the case for me...

The vacuum line was never disconnected.

The flap does nothing to TC, the time it takes the flap to move you would be on your ass. Removing the flap increases induction roar and should change your afrs down low, removing the flap completely should help up top as there is more room for air to flow into the engine. The WSBK team uses the MWR XL intake to increase power over 160km/h mark once negative pressure builds.

I feel this way after every time I do something to a vehicle. Oil change? Feels faster. New tires? Feels faster. Higher octane gas? Feels faster. Slip-on exhaust? Feels faster. I figure I'm just crazy and it's simply the placebo effect.

2013 ABS, Bridgestone T30 Evo, Woolich, Danmoto shorty & link, Rifleman's 1/5th turn, K&N, GP shift, Gen5 shock/links/dogbone, JT (-1/+0), EK, Shorai, EBC HH, AllBallz roller steering, heated grips, shorty levers, MotoDynamic signals & relay, plasti-dipped and vinyl wrapped (all green to black), Bestem carbon, PUIG Pro sliders, solo cowl, modded sprocket cover, TST fender elim. w/LEDs. 45,000km+ and going strong!

I removed the flapper and notice some of the changes , first the noise level is higher , the AFR has been changed some with woolich Autotune log.

the front End comes up faster on power wheelie with TC2 , and I feel that it comes up more before the TC get it down again , so Op statement I can concur most are facts . I still need to ride it more and see if the TC is same as before with lean angle .

Kawasaki must have some really shitty WC if disabling the intake flapper is enough to overcome it. Of course I'm being facetious, sounds like placebo effect to me.

I remember long time ago Anthony had installed one of those XL intakes, but his pump failed and a conclusion was never done...
