Hi all, I just got a 2017 C-Force 800-2 yesterday as a gift. (Yes a gift, holy sh*t) I took it on its maiden voyage which was a good 5 hour mixture of moderate speed open field riding and about an hour of low speed, low gear
4WD creek bed crawling with a passenger. It is truly a beastly machine. My only concern (Especially being a fireman) is how hot this thing gets. Both of my legs were cooking from the heat coming off the motor, trans and my girlfriend's legs were getting toasty from the body heating up. Temp guage was well within limits. When I took the gas cap off, hot, pressurized air came hissing out and I could see the gas literally boiling in the tank. It had been turned off for about 5 minutes prior also. Is this normal? The exhaust is only 2 inches from the fuel tank and everything is covered in thermal reflector tape, but it's still getting hot. I don't think the tank is venting properly. Any thoughts? Thank you!

P.S. I go by Cody and I am from Amherst, VA.

Well, it's probably normal. All of these have a check valve that lets air in as the fuel pump pulls fuel out but when it pressures it won't let the fumes out..and as you know, is the most dangerous part of fuel...and like water, it's boiling point is raised when under pressure so..leave the cap on..lol. It's actually only a few ounces of pressure.

When new they all run hotter then they would when broke-in but many find some pipe wrap helps move the heat out the back better. Of course it's not advised to ride in shorts and sandals, rather riding attire such as long pants, boots (or something with ankle support), long sleeve jersey with gloves and helmet are always recommended. I know all that is hot in the summer but..it is proper...and safer.

All normal they all run like that

Thank you guys for the replies. This is the first ATV I have had in about 10 years, and I am used to the gas tank being in the front and a fancy breather tube just dangling out of the cap lol. I called and spoke with the dealer, and he said the EPA is actually making manufacturers put catch/charcoal cans on ATV's now that the fumes vent into, which is just crazy if you ask me. I feel a little better about the gas tank now at least. I am having a bit of an issue with throttle response at low speeds also. If I crack on the throttle, the gates of hell open and it takes off like Meatloaf - But if I am just putting along at like 10mph, it will stutter and hesitate when I press the throttle intermittently. Could this just be part of the break-in as well? I'm putting 93 Octane unleaded in it currently - Any suggestions on fuel/additives? I know the owner's manual says 89 minimum. Thank you again for the information!

It has 10.03:1 compression pistons so 93 octane may be too high. Try 89-91. And make damn sure you are not running the OE paper air filter. They are death to these engines. Use either the suggested TwinAir, Unifilter or the upgraded CFM foam filters.

Thank you!!! I'm going to run out the rest of my 93 and try some 89 before I haul it to the dealer. I'm going to look into the filters now, and what kind of exhaust wrap would you recommend that won't break the bank?

Oh I never recommend exhaust wrap cause it overheats the stainless pipe and can crack it...but many people do it with no issues. Just do a search for exhaust wrap and it should come up with what others are using. If its heat and noise reduction you are looking for we have other things we have done.

Duly noted on the exhaust wrap. I have been scouring the internet trying to find an air filter that I can put on mine. There is little to no information on the 2017 model yet it looks like, save this forum lol. I saw there was a mods thread for mine but nothing about an air filter. Do you know a concrete part number I can use to get a decent air filter? I was looking at this one:

Again, thank you for the information. You have been very helpful.

Either that one or the straight one which is this one. Take a look at your airbox and see which would be best.

Thank you! I'm on the right track now lol

So I went ahead and checked my airbox out when I got home yesterday from work. The filter comes out and does a 90 degree turn like the other models do, so the one that I had linked should work fine. I will let you know when I get it and install it. Thanks again!
