Have a 2017 missimo 500 won’t idle seams to be running rich new injector fuel pump new air filter what else would it take .

Could it be a faulty  temp sensor for fuel injection making ECU think they engine is cold all the time and enriching fuel mix?

there is a small bolt or screw right beside the temp senser in what looks like a thermostat housing, loosen that screw while the engine is running and let the air bubbles out. air in the system makes the temp sensor read wrong and sends wrong signal to the computer.

      Joyner trooper Fuel injection
      By Nutcase
      I have a Joyner Trooper 1100 4 place that has been sitting for a number of years. I have everything taken care of but i can't get the fuel through the injectors. Fuel pump puts full pressure on them but they don't turn on or spray fuel. Any ideas?

      Thanks for accepting me!
      Haven't got a side by side yet, but have been shopping.   
      Any advice welcome & I am on a limited budget, so haven't decided yet on new or used.

      2017 Cub Cadet Challenger 750 hisun junk motor
      By hisun junk
      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

      I just purchased a used 2023 Massimo warrior UTV SxS 1000mx with 600 miles on it. I didn't even get a full day of riding and the driver's side rear axle broke. I'm pretty sure it was already going bad because we would hear a noise once in a while. I'm wondering if anyone else has had problems with theirs. Also looking for places to buy accessories.
