Postby sgehr19077@aol.com » Tue Apr 17, 2012 9:09 am

Hello, I have a honda urban express NU50. Runs great, idles, starts right up. but after riding 'er full trottle, 30mpg, she stalls. I usually stop, open the gas cap. and screw it back on. and she will start up again, only to stall again. ...Any suggestions????? shelly

Breather hole in fuel cap plugged. Look for a small vent hole and clean it with carb cleaner and poke an pin through hole to clear. You will be probably vapour locking. Also put a in line filter on the fuel line to the carb.
