Hi!
I have a 2006 YZ125, with an HGS pipe and Vforce3 reeds. I've been trying to get it running right and have come a long way.
Current settings:
MJ 430
PJ 40
AS 2 turns out
Stock "74" needle, top notch
8.7mm float height
Will rune OK the first few laps, then it will start bogging/cutting out exiting corners, even at full throttle.
It *feels* like if I pull over and let it idle for a bit, that the issue disappears, but I might be wrong, as i am typing this late at night after a practice day.
What could it be? I tested the gas cap ventilation and I can blow through the venthose, though not sure how free it should feel.
Fuel flow seems fine when opening the tap, with the fuel hose disconnected.
Any leads would be nice.

You seem a bit lean on the needle and pilot. I was running a 42.5 and the stock needle in 2 or 3.
I already read about the leaky reed blocks and made sure there are no leaks there.
You say you are running the needle on the top clip? If that is the case, you may need to look into a leaner needle and try towards the middle.
The Shop
Pretty sure JD Jetting sells those gaskets.
Give that a try.
