My limited experience is the fact that I've never owned an atv with AIS system. But I had an idea how they worked.What do you believe then with limited experience ?
I'm not sure what to think about all this....I have two 2016 700's, other than having to start them twice when cold, they both run fast, hard, and perform reliably. I don't get what the problem is that people are trying to fix by reprogramming the fuel mixture controls. Is it better acceleration? better mileage? or what? I think my quads are super fast and get good mileage now.
Hmmm....Neither of our quads cooling fans come on until we've been really horsing around for a long time, OR until I've been plowing for a long time. Both machines get hot, but all machines get hot when running. There is definitely more heat near the exhaust, but again that seems normal to me, my old enduro's got plenty hot back in the day. If adjusting the fuel mixture somehow increased machine life or reduced maintenance/repair frequency then I would like to learn more about this.Maybe the 2016 are diff but what I got from friends that have grizzlys 700 theyre the same. These machines have been leaned out a lot for emissions therefore making them run on the hotter side. I noticed my machines cooling fans running all the time trying to cool it down. Adding the fuel programmer will enrichen the mixture cooling the temp of the engine down and gaining some performance.
To really know just how lean you tune is you'd need to put it on an 02 sniffer such as a dyno.Primethious you seem to be on board with this concept? My 18 700 does seem to have the fan running a bunch, even when I am operating at low RPM and 30 degree weather. I know that there is little natural air flow through the radiator at low speeds.
