TRW I would leave it also, and I had no idea they could fine tune the EFI. I would stay with that dealer, they seem on top of things. I have never had to good conversation with a dealer. I own two ATVs, and 4 motor cycles. My first motor cycle, and 80 cc 1964 Yamaha.

KodiakAfishyo I called my dealer yesterday to ask them. Service dept. told me they have never blocked off the AIS. What they do on the one's that come in for running too hot is reprogram the EFI system to run richer, and have great results with that (they charge $60 to do it). I went home and pulled my spark plug out to see how mine is burning and after 800 plus miles it was still clean and had a perfect tan color on the insulator. And since I can never remember my Kodiak never having a popping issue and maybe once or twice ever backfiring, I have decided to leave it as is...stock (a none issue for now.)

TRW My first 2016 700 Kodiak, snapped and popped on deceleration and coming down hills. When I took it to the dealer, I am convinced that they lied to me, said it needed a new plug and fuel and that supposedly fixed it. They also did not fix it under warranty (10 hours) as they said it was my bad fuel.(It was not) It cost me over $100, and I complained, but was actually happy they fixed the issue. I wonder what they really did to fix it? I could be wrong.

I have no experience with it but I believe it's a form of air injection system that helps burn off any residual fuel molecules in the exhaust to meet tight emmission standards . Apparently it causes alot of the popping when decelerating. I believe only a fuel programmer can help bring down the exhaust temperatures. Some one can correct me if I'm wrong.

I used some heat reflective tape to go onto the fender above the muffler to cool that area down. Before a passenger had a hard time sitting behind me and now it is more comfortable. My next step is to get the exhaust pipes ceramic coated to help. But neither help what the thermostat opens and closes at and the air flow around the motor and out of the vents on the sides.

The dash gauge on my 19' shows roughly the same temperatures, 206* is where the fan kicks on, and the thermostat starts to open at roughly 170* as it warms up to the temperature quickly during a ride then slowly creeps up to the 195-205* range. Just a quick note, just about EVERY new ATV test rode before purchasing the Kodiak 700 had a Hot panel on the exhaust panel, most notable was a Can-am which would probably cause a burn on your leg if you had shorts on. My Rancher 420s get pretty warm too, but not as bad at the Kodiak.

TRW Wow that is very interesting info, thanks a bunch.

JimP Actually we found out years ago when we were building high horsepower engines that the higher the HP the better the fuel burn was along with the better fuel mileage you got if you ran the correct type carburetor along with the fuel jetting.

We had one Chevy 327 that was pushing 500hp on the dyno while in a car that got a little bit over 30 mpg during the break in on the motor. This was with a 2 barrel carburetor and a 4 speed manual transmission. Now when we put those 2 4 barrel carburetors on top of that engine she drank fuel like there was no tomorrow. But when we put the car on the dyno and stuck the sniffers up the pipes that motor was burning as clean as a freshly changed baby.

The problem comes from people not maintaining their vehicles for peak performance and as the time wears on without a tune up every week things start to deteriorate to the point that the pollution starts to pour out of the pipes.

So now to meet all the federal regulations things are choked down and leaned out so much other problems come up. But the engine builders don't have to worry about it once that vehicle leaves the showroom. It is now up to the consumer to take care of it.

TRW Thanks JimP, I have limited knowledge on this pollution control stuff, I do know that the fuel burns so much cleaner than when I was a kid.

But then your chainsaw is using a oil/gas mix and will smoke due to the oil.

But it isn't just the smoke that they are regulating but all kinds of things that you get when you burn any type of gasoline.
