I have a 2020 Cforce400 but only use it for recreational riding and not to work on a farm.  I take care of it but I do ride it hard and not baby it.   It has been an ok machine but since it is my first atv I cannot compare it with anything else.  The normal service is pretty easy with a couple of basic tools and just a bit of mechanical ability.  There is however on the service manual a call to check the valve spacing every 1000 kilometers which seems to be a CFmoto thing only.  I have change the oil, air filter, belt and one way bearing myself (don't worry it was not the machines fault, I killed the belt and bearing for just bad use). I have added a rear mounted winch and also made a small trailer with the same hitch a ball system to just move stuff around. 
The radiator fan died pretty soon after delivery and was replaced under warranty.  Also not sure what happened but the 4wd stopped working and again was fixed by the dealer with no issues ever since.
Hope this helos and If you have any specific questions just let me know.

There is what I found:
-All lights are display in the dash for about 3 seconds (picture 1).
-Temp disappears completely right after (picture 2).
-After 12 mins of idling still no temp reading (picture 3).  Weather was 65 degrees.
-Finally after 14 mins of idling the temp is displayed with a "C" (picture 4).
-16 mins idling and a fist bar appears on top of the "C" (picture 5).
-19 mins idling and second bar appears on the temp gauge (picture 6). It sits at that temp all day long.
Went for a ride and the "H" never appears.

I have a 2020 Cforce 450L.  In my case all the lights in the dash work fine.  It takes a extremely long to get the bars on the temp gauge to show on the dash, it will only happen after the engine has been running for quite a long time (maybe 5 minutes or longer).  Im sure it gets up to working temp but the bars on the dash take long to show.    My radiator fan stopped working propperly, it was turning on but not blowing strong enough to cool the engine.  The fan was replace under warranty pretty soon after I got the machine.  With that replaced the temp are now kept cool.  I will time it tomorrow and see how long it takes to get the bars on the dash. The normal operating temperature for my machine is to show 2 bars on the temp gauge. 

The fuel gauge is a bit.....temperamental.  It works fine as a reference but is not calibrated or precise at all.  It show a full tank but it goes down in a hurry and will show an empty tank prematurely even when there is still about half a tank of gas if I open the lid.  It is something that I learned to live with and dot trust much at all.

Another thing is the speedometer which is off and marks a faster speed than a GPS App on my phone.  It show about 6kph faster that the GPS.  I don't know if this is something that can be calibrated or programmed for a different size tire.  I have asked the dealer and never got a straight answer.

I will report back tomorrow with pictures of my dash.

It's funny the you star combining your hobby with you other hobby and somehow nothing gets done 

I flew my drone today after a year and boy I am out of practice.

That is decent flying....all it takes is more practice.  In my experience it is easy to tweak the controller for the drone to react slower specially when panning or changing direction from going forward to start a roll,  the slower the transmission the smoother the video.     Nice place to film too 

Awesome views nice photos.

Welcome to the forum, there are some great members here.  It would be nice to see your machine.

Can confirm my 2020 Cforce 450L does have a one way that was expensive to replace once I lost engine brake.  A new one way bearing fixed the problem and now I can slow the machine down to almos a complete stop by just idling it. 

Thanks... my machine is in the shop now but is a holiday so I won't heard anything until next week.  I will report back with any findings. 

Excellent, thank you once again NMKawierider you are great.  I will change my receiver box to that auxiliary port.  Do you think that little bitty receiver box is enough to drain the battery overnight and not let it crank the engine?

If you are going alone with no other vehicle maybe consider taking a jump starter for extra peace of mind.  I always take mine

But there are tons of options out there.

Thank you very much NMKawierider I now have to change the receiver for sure as its is getting power all the time and even with the machine connected to a smart charger (a Noco Genius 1) my atv will not fire-up after 2 months of no use with a one year old battery that cannot crank it any more.
One quick question, what is the accessory plug you got power from?  Did you splice the positive wires to tap into the 12 volt cigarette lighter port?
Is your factory winch wired straight to the battery positive and negative with no inline fuse anywhere?  Mine came that way 

Thanks Skygazer I never considered the constant power draw...wonder if that is why I am now having to replace the battery prematurely.  I mounted the cheap amazon receiver to the original OEM winch that is wired straight to the battery.  It is surprising to see that there is not an inline fuse in between the battery and the winch.  My problems are that the remote control works sporadically, sometimes it stops working in the middle of the operation and other times I have a hard time getting any reaction from the winch and have to press the button on the controller a couple of times even with brand new batteries on the remote. There is a slight delay but that is something I can easily work with and just like you NMKawierider I do have soft rubber stoppers so no problems there.  I install the receiver such a long time ago and I never consider to put it on an acc power; I now have to do some research and relocation to get that done properly.    Is your All Balls setup still working now Ulfthednar?

Hello, I have a 2020 cforce 400 with more that 1000 miles.  No problems with brakes of plastics getting hot.  I did have a problem with the ignition switch and light switch not making contact but took the apart and cleaned the rust that was there...now it works just fine but I do spay WD40 often on all the handlebar switches.  Hope you get the problems sorted out.
