Engine wont STAY running ??
Got a 2000 Honda 400EX stock engine..
Starts up fine.. idles smooth.. will idle forever it seems.. but once i start reving it.. its like the engine just seizes ! its shuts up instantly and wont fire. cranks over VERY slow like a dead battery but battery has a full charge.. then once it cools down it'll fire right back up and idle.. Im at a loss.. figured id give this a shot before i take it into a shop..
