I recently ordered some parts for my 2017 MSU 500 and when they came there was a brochure included that gave some hints for making Hisun motors run better . Most of them made sense but one suggestion was to raise the oil level by 3/4qt. (bottom of dip-stick threads) to improve wet shoe clutch wear . I'm not yet familiar with the power train on UTV's (but I'm a-larnin') but this goes against what I was always taught about overfilling oil levels. These guys seem to know their stuff (Motorcycle Doctor ) but I'm wondering if anyone has any input on this .
BTW...They did have one good suggestion about blowing all of the old oil out of the oil cooler when doing an oil change. When doing an oil change on my cars, this is something that I've always done ( I was taught by an old school mech. MANY yr=ears ago) but is rarely ,if ever , done in a garage. You'd be surprised at the amt. of dirty oil that you avoid adding to your fresh oil. Just remember to recheck oil level after running the engine and top off the oil.

i have a 2017 cub cadet challenger 750 camo, after a month of nonstop work with the pandemic i was finally getting a chance to ride it. it would not start, the battery was dead, went to charge the battery and noticed a mouse had chewed a yellow wire one of2 going to a block of some kind in battery box, it is tied into the 2 fuse relay breakers attached to the starter relay. there is a red with stripe wire that goes to a harness below the rectifier in engine compartment, it has no power to it with multimeter and the fuse block is getting real hot. other than that the dash lights up, but no readout and the gauges dont cycle, the fuel pump does not start. on the fuel pump i checked the red wires to the cdi and both have contact and are intact but one does not have power when the key is on and there is no spark i tried starting fluid. i have swapped out the cdi from my cousins same year and model, also the ecu and the main relay. i have no idea where to look now. his has broke the shim again and will not start. also i did notice that i wiggled a wire connector going to a sensor on the engine and a couple lights came on on the dash, the stirring wheel one and check engine but only did it once and i cant get it to do it again. i have looked over the harness for anymore damage and have found none.
has anyone seen this problem before, is it wiring? ground? what do i need to check next. the place i bought it has no service the guy said he could only swap parts and try. sent me to another place over an hour from me and that guy on the phone said he was covered up and didnt know when he could look at it so he must be busy lol. besides i dont want to have them charge me $3000 to replace everything on it before they get going.
my advice is do not buy a cub cadet, we thought we were getting a cub cadet and it turns out it is a cheap chinese pos. i still love my cub but wish i had known this before i bought it and i would not have.
any help would be appreciated thanks

I recently inherited a 2014 MCU 500. A nephew accidentally put diesel in the tank, proceeded to run it until it stalled out. We proceeded to empty the tank and put fresh gas in it. It ran maybe for 10 minutes then shut off. Haven’t been able to get it started since. That’s when I started to mess with it. This is what I’ve done so far. I might add I know the very basics of on engines so I thought I would come here and get some advice.
- emptied tank and lines leading up to fuel. Filled and primed with new gas.
-cleaned air in-take, it was pretty dirty.
-did a full oil change. I felt like there was definitely diesel mixed in.
-changed spark plug. Tested and working appropriately
- tested fuel injector and it appears to be working
That’s where I’m at so far and still nothing. At this point looking to see what the next steps would be in trying to diagnose what’s going on. Appreciate the help in advance.
Thanks,
Harrison

I have been going through the troubleshooting in the manual (pages 17-38 and 17-39), but I can't find anything that looks like the picture in the manual. If I run power directly to the pump, it will start and run but otherwise won't start.
Any help to this old nubie will be greatly appreciated. My background is electronics, not vehicles.

This is a carb model not EFI it was in pieces when I got it. I got it running by replacing the fuel pump had to bypass this little reservoir thing I can’t find how it goes back in please help. Machine runs good but I have fuel coming out of the drain on the carb. This is a pic of the reservoir thing thanks
