Had some issues where I was losing power on my Hisun.  Got it back to my shop and it wouldn't start.  Drained the fuel, replaced the plug, injector and TPS, cleaned the air filter.  It will start without the air intake attached to the engine but once I put it back on, it will die.  Any ideas on what else I need to do?

Work backwards from the TB air intake boot.  Suspect the critters made a home in the air box or the air filter got wet.  If you find an air restriction...great.  IF not, you need to give more information as to the running conditions with the air intake reinstalled......running rich?, will it rev up with throttle?, lost the MAP sensor?, etc.

      2022 Hisun Sector 550 eps. Power steering not working
      By A P
      Hi
      I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

      2018 Hisun Sector 1000 Crew stalling but starts right back up. Please help!
      By Jon Spruill
      Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

      bd 300 bulldog shifting issues
      By Dennis
      I have  a bulldog i bought from home depot in 2013.  In the last season it started refusing to shift from neutral to either forward or reverse.  I changed the trans axle fluid and made sure the cables were lubricated and free.  With a lot of coaxing, I can sometimes get it to shift.  once I start driving it, things improve until I let it set awhile.   Any suggestion on where to go from here?
