2015 Yiban Delray cuts out when giving more than 1/8 throttle. I changed the plug and fuel filter and gas cap, but it still does it. I can get to about 7 mph before it dies out. Sometimes, it runs with no problems for 10 minutes, then I'm walking it home. It is fuel injected and sometimes it smells of gas, so I'm guessing it is running rich. enter image description hereenter image description here

    Welcome to the site. What is a Yiban? I did a cursory search on Google and it popped nothing which would work for this SE ... ? I'm assuming it's either a motorcycle or a scooter? – Pᴀᴜʟsᴛᴇʀ2 Jun 16 '17 at 17:33
  • @Pᴀᴜʟsᴛᴇʀ2 based on the model number, I would assume a generic 139QMB-based scooter – Ceshion Jun 16 '17 at 18:08
  • Make sure you have good fuel and there is no water in the tank. – CharlieRB Jun 16 '17 at 20:11
  • Yiben/propel delray yb50qt-5. It idles with no problem think it could be fuel related to the top end. I just drained the tank and put freash gas and its still doing it. – Dkhope86 Jun 16 '17 at 21:37

The old owner told me that he left it outside for a month in the rain. Water got in the carb and added dry gas and let it run for 3 hours at idle and it runs fine now. Just got back a day ago from out of state family emergency things are good there now too
