Grizzly 450 issues

[Shadow soul60]

So we have a grizzly 450 and it has a few issues. It's the main work quad now that my brother's Kodiak has started burning oil from wear. (It's got probably 4000-5000 miles on it)

One issue with the grizzly is the 4 wheel drive doesn't kick out. We haven't really investigated into it but long story short the 4 wheel drive is permanently engaged. Before it just kicked in and out sporadically, now it just stays in 4 wheel drive permanently. The issue this brings is the quad burns through gas like mad, it goes through a whole tank in a week.

It also needs a tube in the tire, but that's a lot easier to solve.

Wow that’s a lot of miles on the bike #workhorse.  What year is the bike and what’s the 4x4 shifter look like? Is it electrically  or mechanically switched?

The kodiak has had a lot of travel, with almost no issues.

The grizzly is a 2013, I think. My quad sat for 4 years so we got the grizzly to replace it. The 4 wheel drive is a button on the handlebars, so it's electronic. Most of the safety switches have been bypassed, including the neutral switch and the Brake switch. Everything works except the 4 wheel drive.

Ok well it’s most likely something to do with the wiring then.  I don’t think it’s mechanical and more so electronic. Best bet is to start looking at and studying the electrical diagram and highlight all wires related to the 4x4 change over.  I can give you a hand with that once you know for sure the year.  Check the vin# and run it. See what comes back.  

Then we find the right  manual and start to dissect the electrical diagram and you can do some testing if your familiar with using a tester.  Maybe start with the push button changeover and make sure it’s working and go from there.
