I don't know if their the exact same engine 2014 and 2015 Grizzlys (like you said not much info) But they were very lean running engines as well.Just picked up a 2019 kodiak 700 base model with the 686 in it. I did as much research as possible but still found very little for the 686cc 2015 and earlier. Are these engines reliable? Did the old 686's need fuel programmer to stay cool?
they were solid stock, and most likely, yours will be too, but they all benefit from a fuel programmer. they all run a bit lean from just above idle , to just between 50 to 75% throttle, then they are just about right the rest of the way to WOT.Did the 2014/ 15's need or benefit from the fuel programmer or are they solid reliable at stock?
