Hi Guys
I have a 1984 YTM 200EL that will start up and idle, but when I go to rev it up in neutral it sputters and spits and bogs down. It won't start without pulling the spark plug and squirting some carb cleaner down it when it is cold, but once warmed up it will start first pull. I have cleaned the carb twice, which it did need, and it ran like a champ for a while after that. The spark plug wire and coil look to be either origional or very old. The coil says F6T509 on it, making me think it may be origional. There are no other wierd wiring problems on it, and the guy who sold it to me (a Moto Guzzi dealer who was using it during motocross races to run around) said he thought there was an electrical problem. Could it be the coil? Or the CDI? The spark plug comes out black or dark brown after just a few minutes of idling or running. When I lay the spark plug against the motor to test for spark - sometimes it sparks strong and sometimes it looks like it isn't sparking at all. Like I said- it idles fine, but bogs and backfires and spits when revved. :wondering Thanks for any imput.. Tad
