recenctly got a 2006 suzuki lt-z50 for my 5 yr old for his birthday. ran a little rough from sitting so i removed and cleaned the carb and it seems to idle and run very well now. the only thing is it seems to cut off alot on the kids.. especially when going through a ditch or something like that. i think when they quickly remove their thumb from the throttle it somehow cuts off and they have to crank it again. idle is fine. when the bike is under load and you quickly remove your thumb, the rev goes down very low before coming back up to idle. did i miss something in the carb? any opinions would be great. thanks alot, justin.
