hi just  bought a 800 uforce wanted the zforce800 but am mildly disabled and getting in and out of uforce is way easy-er but so far am really impressed would have liked the extra suspension but all the extra space is some compensation , having had to fix many of my 2 sons atvs and utvs i think it compares well to the big boys .i an a bit worried about how lean it runs stock , think a EJK controller is in my future ,mainly to keep things cool and healthy

Seems to me that all of them run too lean. I wish there was a cheap/easy fix. A little bit more fuel would make me and the machine feel better.

Not sure that they are too lean...normally..just on the edge sometimes. Too lean would produce some problems that they just don't have...IMO

I richened mine up once with air restriction and other then watching the gas gauge drop like a rock, didn't see any real gains.. or losses in power or change in temperatures.

i think your phrase close to the edge is right , a hot summer day, lots of dust and puddles to dirty up the rad then a 20 minute ride on a fire road is all it would take running this lien ,running 12.5 afr is dam good insurance in our operating environments . I am going to order one it seems to me that the exhaust is restricted , to much back pressure , just feels unhappy when you rev it so if i release the pressure i will need a controller . Another thing i noticed is although the air filter is nice and high the intake is  at least 12 inches lower , that will have to be addressed as where i live is called lakeland  water every where !!

Congrats, now get out and log some miles on that buggy!

I agree, they dont seam lean to me, and the 23 MPG reported is awesome. I think wiring the fan to run all of the time and a coolant upgrade is the ideal safety margin they need. That, and Ethanol FREE fuel.

So.. did you ever buy one?

By the way, just general info, I'm pretty sure these like most UTV/ATV fan motors in that they are not rated S1 (Continuous Duty), most are S2(Short Time Duty) so running them all the time probably will drastically shorten their lives. Although I can't confirm the rating but I just can't see CFMoto using a better fan motor then anyone else...

i dont think i will wire it to be on all the time but i think putting it on a switch is a good idea after reviewing the history of the thermoswitch , i have messed around with alot of engines , and learned that if u can get the afr around 12.5 they run so much cooler and happier . That and uncorking the exhaust  makes a huge difference to the general demeanor of the engine  a ejk controller and a massage of the exhaust are top of my list.I also think the exhaust is going to get wrapped , only 250       kms and the wife doesnt like the heat on her leg ,i think this is more of a problem with the uforce because the engine seems more forward

No Sir, This week has been hectic for me on a old home restoration i am working on. New water lines for the mountainside, new meters, and new service line to the house.

I am still really intrigued with the Z800EX, as something about it really speaks to me. However I still am looking heavily at the yamaha wolverine r spec as well.

Side note....we ran my cousins Brute Force fan full time, from day one, no issues. Did the same on his Yamaha Raptor, and I have my DRZ400 fan setup on manual switch operation, but run it full time when in the woods during the summer. It may shorten fan life, but it extends motor life so its a trade I am willing to make!

Agreed on the fan switch. Planning on installing a bypass switch as well in the near future.
