ah, my idle rpm is preety high on my hysoung GT250R, its around 2000 to 25000 (some times to 3000). Rarely it goes down to the normal range. A while ago, there was an accident where oil got into the petrol tank (long story) and i had to drain out the tank and the carburettor. And when i refilled it with petrol, i noticed that my idle rpm is quite high and also the engine seems to sound like its hyper. I know its not the throttle cable, so anyone got any ideas (apart from digging a hole for my hyosung or buying a new carburettor )??
