Questions on 2017 Challenger 750 crew


Recommended Posts

Hello everyone.  I purchased a 2017 Challenger 750 eps Crew with 400 miles and find the exhaust noise is awful.  I saw in another post chatter about a 2019 exhaust upgrade?  Anyone have info on this?  I also would like to know the typical RPMs for speed.  I am running 4k at 20mph in hi range and it seems like it does not have the power I expected.  

So far I have added a custom mount rear winch, soft rear window and upgraded LED headligjt bulbs.  I am looking for any other upgrades people have done.

Well that could be.  I have seen other complaints about the noise.  I dont have anything to judge it by.  I am going to take it to the dealer and have him go through it.  The machine is like new and Im getting 15 miles per gallon so it seems like engine is running efficiently.

The exhaust upgrade does not do much for the noise, it just removes the likelihood of breaking the pipe going to the muffler.  Most of my noise cam from a cracked pipe. It helps to duct the air piping from the clutch to the rear of the cab.  Both intake and exhaust.  Mine runs 5500 rpm at 40 mph.  6000 at 45.  The gas mileage was much closer to 25 mph.

      Howdy Everyone,
      New member looking forward to learning and sharing more about UTVs. I have a 2019 Coleman Outfitter with the Hisun 550 engine. Does anyone know what Code Scanner will work with it ?

      I’m getting a 700-7 every startup. I’m having to change the plug every 100 miles on 93 octane gas. I got a lower numbered plug that is supposed to burn hotter. I’m wondering why that comes up every time I start it and if it’s related? I included a picture of the code or whatever it is. I haven’t seen the code in the owners manual or the hisun shop manual I have.

      I'm working on a Coleman UTV 400 that has a rough idle, owner has had it for about a year. When I say it has a rough idle, it doesn't have the continuous smooth running sound. At times you can hear it kinda skip, sputter, or like the RPM has fallen (RPM stay constant according to the gauge) It's not as bad as it was after I replaced the fuel filter and fuel injector (both are Chiki) not sure if that is a quality brand at this point. Checked the spark plug, it was a little foul, but not too bad. (Since the engine is still idling bad I'm going to replace that) Cleaned the throttle body making sure the carbon and soot has been removed, and the air-filter has been cleaned. New fuel is being used so it's not old or been standing. They did tell me that they were using non-ethanol fuel, not sure if that would be causing the issue. Next two things I can think of that maybe the issue is the O2 sensor or the valves need adjusting.
      Thoughts and suggestions? Thanks in advance.

      I have alot of issues with this machine that I'm trying to figure out and fix.  Today when I was fixing the shifter I see this cable connection that is not connected to anything.  I looked and can't find where it might need to be.  Any ideas would be greatfull.
