I have a 2002 Prarie 650, and a 2021 BF 750, and I noticed the 650 does not have the high heat problem on the left leg like the BF 750? I observed that they used a "Deflector" on the Prairie 650, and they used it up to 2013 on the BF 650's? Well I first tried fitting it on the BF 750 (Not Happening) so I made one and it works great!

I'm totally interested in this mod! Please share your details too make one Please. Or else I'm fixing to spend mega $ on new exhaust system and tuner, because I'm tired of being roasted, and my wife hates the bike because she gets burnt up too. I also have a 21.

Do the newer Brutes run hotter? I have not had this problem on my 13, but I always wear jeans so maybe that's why I haven't noticed it as much?

Seems to be an issue. But the left leg takes a beating from the heat. I like to wear shorts in the summer. The heat is the only real problem I've had from the brute. Other than that, it's a bear in the woods. I'm gonna research for the plastic shield mod.

I used 3/4" x 1/16" for most of it, and 1"x 1/16" piece on the rear (Aluminum angle) that I got at Tractor Supply , Mounted to the underside lip of the BF 750 with 10-24 x 3/4" machine screws with lock nuts and washers (Stainless Steel or Zinc Plated) The Plastic is 3/16" thick that I cut from some Truck Mud Flaps that I had (Any Plastic will work) I made a Card board Template before cutting the Plastic! Take your time and do a good job!

I went ahead and decided to give this heat issue a try. I couldn't find the material I needed in the short time I was home, as I did a quick round trip to retrieve my ordered Elka Stage 3 shocks that came in earlier than I was expecting, and I am out of State with the Brute.
I went ahead and installed 2 carbon fiber heat shields on the front Brute Header exhaust pipe (Wow, those aren't cheap in cost) and also decided to add some additional heat management on my left leg,
I tested it a little yesterday by crawling up a steep rocky section trail in 4x4L and it worked fine but I need more testing to see if my heat blocker will do the trick or not. I don't want to block off too much of this area, concerned with the heat that is generated in that area. Kawasaki's heat shield that is bolted onto the front header pipe is a joke, I think it is more to protect the side plastic from melting.
I used 1/2" wide aluminum angle bolted to the lip on the left plastics, self-tapping metal screws painted black, thin piece of sheet metal with heat tape applied to the outside of the sheet metal, rubber section cut to fit onto the sheet metal, it too heat taped, and another rubber section (heat taped too) attached to the other rubber piece. If I have issues with the rubber melting because of the heat, is

the reason I used the self-tapping screws, I can take the entire piece off with a Phillips screwdriver at the 2 top screws.

Nice work! I know from using mine that The Heat Issue is greatly diminished without any over heating issue's. Because I tow a pretty heavy load several miles up some steep hills, and I have done some rock crawling with it in some very warm weather!

Have done few more rides with this mod, results: This homemade heat guard does work, also the 2 carbon fiber heat guards I installed. The left plastics are extra warm to touch with your bare hand after a long 4x4L steep climb but only towards the rear section of the side plastic and only where I don't have a carbon fiber guard mounted on the front header pipe. Probably will add another carbon fiber heat guard on the exhaust header pipe towards the rear section of the left side plastic. Before I installed the 2 carbon fiber header heat guards you could Not put your bare hand on the left side plastic as it was way to Hot after a slow going steep climb.
The homemade heat guard mod is only slightly warm to the touch with Zero Hot Heat on my left leg-a winner for sure.

Excellent! I was just out yesterday Rock Crawling in the hills of CT and I was wearing shorts, no more heat on the left leg, no overheating issues! FYI: All I used was a 1/4" piece of Plastic from a Truck Mud Flap without any of The Expensive Carbon Fiber, Sheet metal, and Heat Tape that you mention. So let's keep it simple and inexpensive for all!
