its not the fuel injection you have to worry about in the cold, its how much amperage you have for cold cranking.. more the battery then anything...I couldn't find any detailed information on the fuel injection and the lowest temperature that will be perform in. Maybe someone can find a mmore specific number for the Grizzly? They are similar and both are made by Yamaha.
yea most people who are expecting to put it to work in more adverse conditions will make the investment into a top shelf battery...I still couldn't find anything about this on the Grizzly but a few people solved the issue for the Polaris by switching to a battery with a little more capacity or just a larger battery than stock to fix the start up issue. Maybe the same can be applied to the Kodiak and Grizzly.
wonder if thats a battery issue more then anything?Not sure about the Kodiak 700 but someone from another forum has complained that he has trouble starting his Grizzly 700 in temperatures around 10f to 0f. He had to idle it with the starter.
I would imagine that most people wouldn't ride their ATV in sub -20 degrees celsius.
