Nsr 125 problem 105km/h

[RSD00]

Hi, i got a problem with my nsr 125 (zdcjc22b)
I have upjetted carb, carbon membranes, br9eix ngk iridium
So 2 days ago he was equiped with air filter OEM sport, my carb was full of misery and unregulated, 0-100 very slow 130km/h max speed in 6th speed at 9000rpm.
I took of the sport filter cuz “alain in his nsr 125 tips said original airbox is the best” , so i put the original airbox and i go to mechanic to clean and adjust my carburretor, after this my nsr goes really fast to 0-100km/h i have 105 in 4th speed 6000-7000rpm and he locks there, rest of 4th speed is uselist, 5th speed, 6th speed too.

What could be the problem ?

Sounds like a speed limiter, especially if it gets there really easily but then hits a wall.
If you slow down and bang it into 6th will it accelerate to 105?

I dont think is an speed limiter cuz before when carb was full of misery and unrregulated he goes to 130kmh but very very slow 0-100

And now it goes very fast to 0-100 and at 105kmh locked

If i slow down and i go in 6th speed he reach 105 and locks

on Saturday he will open my engine to see what could be

It won't be something mechanical. It'll be a change on either the induction, exhaust or ignition systems.

Edit: unless it has a power valve that's not working.

you are a bit heavy !
i told you : only use the genuine air box
the best way to block the engine is use trumpet filter
