How to tune a CBR 125. HELP! PLEASE

I’m been trying to tune the bike after re-building the carb.

I get the bike to start by adjusting the mixture screw and the idle and it all works fine.

Come next morning the bike starts but when I open the throttle it sounds like its struggling… (rev up and down slowly) and then it cuts out.

Is there a simply way?

Please.

take it to a garage :Whistling: (sorry cant be much help)

That sounds like carb flooding…too much fuel.

fit a 250cc motorcross engine!!
