So I just recently bought the dio reed valve/cylinder and oko carb assembly along with the windowed Cdh piston. Prior to this my bike ran fine with the nt carb stock setup. It revs stationary fine from high to low but as soon as I throw my leg over it and let the clutch out it dies in the higher rpm. Is it clutch related or carburetor related? I’m confused because it ran fine all stock. Any help in the right direction would be much appreciated guys and girls thank you

Welcome to the forum, if I understand you right you are trying to start from a dead stop without pedaling, without very low gearing that will be hard to do. Pedal up to 5 to 6 mph and gradually accelerate from a there. Is the carb jetted to be used with a reed intake system? If it’s not reed valve systems need a larger jet than a stock piston port engine.
