    AG200 engine problem

    Just thought I would let you fellas know that I stripped and cleaned out the carb and replaced the air filter in my AG200 and now the bike is running as good as new. Thanks to those (Yamaha356 & Alyx) who contributed to fixing my problem. Cheers Mingara

    AG200 engine problem

    Yamaha 356 thanks for your advice. I was afraid someone was going to suggest a carby cleanout. One other thing I will ask about is the air filter. If the air filter is in need of a clean, could that affect the running of the engine and be a cause of the dirty spark plug. I took the aircleaner off the bike and ran it without the it for about a minute. What I noticed was that the engine seemed to run better but then it backfired a couple of times. Is it normal for a 4 stroke to backfire when the aircleaner is off. Just a thought before I tackle the carby thing this weekend. If anyone else feels they can add more suggestions to my dilema please feel free to comment. Cheers

    AG200 engine problem

    Hi all I am a newbie in need of some advice regarding my 1990 farm bike AG200. It is runnning rather rough and an inspection of the spark plug revealed it was black. I suspected someone may have put 2 stroke fuel in it so I emptied the tank and replaced the fuel. I ran the engine to rid the carby of fuel as well. The bike was not blowing smoke at all which makes me a little unsure about the 2 stroke being added. Anyway I took it for a short ride and it was okay except for a little bit of a surge now and then. When I got back it idled for a while so I thought it was okay. A short time later I started it (which took a while) and it was running roughly again. Any suggestions welcome. Thanks
