Kxf 80 dies when warmed up.


my daughters kxf 80 has been having a tough time staying running after its been good and warmed up. It usually starts dying after a half hour or so of riding and start back up just fine if you use the choke but will die a few minutes later. It has fuel and oil just wondering where I should start looking.

Too lean of an idle circuit. Need to change you pilot jet or first trying adjusting the air/fuel screw on the carb once the bike is good and warmed up. If you turn the screw more than three complete turns out then your idle jet is to small and you need to install a larger one.
