Shineray XY250GY-2 MX carby clean and New Twin Air filter

So i pulled me carby apart and gave it a clean. I was on a websit called nightriders.com reading up about the tk mv 30 cv carbys when i came across this mod.
So i bit the bullet and did it.
Its a hole you drill out a little bigger on the slide with the needle and diaphram.
I used a 3mm drill bit.
Drill the hole next to the needles hole.

This is the piece you be modding.
The hole is for vacume only and it give more mid range.
I finnished this off with a twin air air filter.
Its a ktm direct fit.

Now its back together and took it for a lap around the block and it does feel i woke something up.

This is the old filter that came out. Its got ipone filter oil on it but its probly a little restrictive when it comes to air flow.
