Need help..I purchase a one owner NC50 Express...starts and runs fine. I installed a new plug, removed and cleaned the carb...reset as instructed on the WEB. I am 230 lbs....scooter will only run around 13-15 mph. Once the motor reaches top rpm it will sort of sputter and if I back off of the throttle a bit it smooths out a little. Any suggestions as how to get it running smoother at top end and also how I can get a bit more MPH. Thanks to all...from a 58 year old kid !!!
Also looking to purchase a nice, clean, low mileage ExpressII or Urban Express....or Honda Passport....Ohio,Michigan, Indiana Area...Scalenut@hotmail.com.
