so I pick up a 2000 rm250 and its seem to run good but it will not idle. I can start the bike with out the choke but unless I give it a small amount of throttle it dies. I have notice that if I start the bike with out the choke and then choke it once it is started that it will have an easier time idleing. being that I am new to dirt bikes and never really played around with carbs before I am not sure what this is telling me. I have not pulled off the carb and cleaned it yet and I am think that would be a good place to start. any tips where to start looking if cleaning the carb does not help.
