Most of these scooters are designed ton run lean. They will start and idle and stall out several time until warm but you cannot accelaerate without it stalling. And that's exactly what they do. There is an air adjustment screw on the bottom of the carb toward the engine side of the intake. Remove the air filter assy and use a small round mechanics mirror to look for it. When you find it use a short strait bit, you've seen them in tool kits they fit in a 1/4 inch socket but you will not use the socket just your finger and adjust out another three turns while running. This make and immediate improvement. Try accelerating after each adjustment, it should accelerate better but may have a slight hesitation yet. It may idle a little faster than you're used to but a small price to pay to get going down the highway. You still may have to move it out further. . Re-install the air cleaner this should remove more hesitation yet. These bike will also run a little on the high side on the temp guage when going down the highway. Still working on that. This is the best you will be able to do with out modifying the jets. Rob - [email protected] on vacation but will be back 7-20-08
