Howdy! I'm new to the world of motorized bikes. I just bought one second hand about a month ago, and at first all was fine aside from a few minor replacement parts such as the fuel line, air filter, and clutch cable. I currently have the air filter off however. Here is my problem though after riding it about roughly 30 miles, I can still turn the engine over but everytime I go to give it gas nothing happens, and in a few seconds to a minute or two it will just stall out. I have no clue what it could be. I checked the carb, the clutch, and even the throttle itself, but it all seems to be in good working order. It just makes no sense to me as to why this would suddenly happen. Would anyone have any ideas as to what it could be, and what to do about it? Please note I'm not that mechanically inclined so I could use all the details you could give me. Thanks. By the way I hav a 80cc 2 stroke but am unsure of the brand itself.
