I have a 1991 Kawasaki 650sx it starts every time but when i get past 1/8th of throttle it loses power and i would describe it as a "chugging" noise it is still running but it won't take off. the engine shakes around and bangs back and forth. i don't know if it is some kind of fuel problem i have tried adjusting the carburetor and i checked the spark plus and the spark. i don't know what to try next. any ideas will help thank you

sounds to me like you have a clogged jet. try and running some carb cleaner first through that and if it doesn't work your going to need to rebuild the carb. also a tune up on the ignition wouldn't hurt
