RM 125 BOG

I recently bought an 03 rm 125 it seems to start up great and all and warms up with out boging at all. I go to ride it then when i get on the gas it just is all braaa braaaa and then as soon as i feather the clutch it gets right back up and then keeps doing this when i let it off or shift. I run 32:1

Did this problem happen on it's on, or was some work done to it, then it started?


Has the bike been sitting for an extended period of time?


Did you change to a different type of fuel, and what type of fuel do you use?

It might be your air fuel screw .. Located between the air box and carb. Try adjusting it all the way in then go 2 turns out
