Hey guys I recently got this gt250r ran mint for about 5 days no problems then one day died then now evrytike I give it more than a quarter throttle it just dies iv checked everything I can so far I have fully cleaned the carbys just put 2 new spark plugs and it’s still doing it.
the bike does start and idle fine and when put in first and take of it splatters and won’t go over 30ks with a quarter throttle if I give it any more it just pops n backfires n goes no where or it’ll just die straight away

Did you change the black piston slides inside the carb?
What jet sizes are you running ? (pilots and mains)
Have you modified the air intake in any way ?
Adjusted the float height?Trying to rise the revs and it cuts, sounds like the slides got stuck or bad mixtures (fuel mixture screw tampered with) or jets possibly too small (unless clogged again)
