yfm 80 moto4 carb help
hello all i have a 1985 yfm 80 moto4 with carb problems . it starts fine but while it is running at idle or driving, it revs itself up. i have to choke it so i can put it in gear. i have had local shop clean the carb and they said they can't find anything wrong with it. when it does rev itself up it is about half thottle. really hope someone can tell what i need to fix this problem. could it be the thottle needle? kids are driving me crazy wanting to ride.
