Hesitation occurs most notably first thing in the morning when l start the bike.Somtimes it will also occur while l am riding with the engine already warmed up (accelerating with the throttle but not just coasting or starting from a stop). l bought my scooter new and currently it has just over 4000 km on it. Another problem will also occur when l am driving at speeds between 55-60mph. Suddenly l will lose engine power and the bike will slow down. If l pull over and wait about 15 seconds, it returns back to normal.

Clean the carbuerator. The same thing happens to my dirt bike every now and then.

get an oil change put new good gas in and clean the carbs out l think they may be gummed up and make sure it is getting airflow
