New OEM carb has to be jetted for the pipe. Gotta get that clean burn.

Let it warm up 🤣

These bikes are notorious for this.

It’s the pilot jet! That’s the only reason why the bike would die it’s not getting proper air to fuel ratio

My crf150rb is brand new and this is exactly what it does. Soon as you barely twist that throttle, it quits.

Come on vee this the one to show us how to tune carbs💪🏽

So you have a idle adjustment screw and you also have a mixture screw on the bottom of the carb very difficult to get to to turn in most cases...but the mixture screw on the bottom (small flathead brass golden screw) will adjust your pilot jet mixture what you need to do if loosen it slightly and keep swisting the throttle every time to see if your making any improvements to you bog issue, also i would pull the carb and clean it with carb cleaner and an air hose and add a fuel filter to your fuel line btw coming out on you pilot scew increases fuel at a low speed throttle you also have a main jet which controls fuel at mid and wide open throttle your main jet is probably fine but anyways man if you need help let me know i live in Florida or message me back on her and i will help

When these things are warmed up - they rip !! But starting them cold sucks BAD ! pain in the but to get jetted properly.

Prob dont even need that new carb just need to clean it up

🍋🍋🍋🍋 if he just needed a carb clean

A good cleaning and she will be running mint

Too much fuel twist the screw man🤣🤷‍♂️

I have one just the 08 model and when he is kicking it It don’t sound right

Gotta be carb. But rings may be on there way out also

It’s the fmf doing it it ain’t Jetted for it

It's a rb big wheel

I hope that's his son's bike and not his
