Hi everyone I have recently bought a 2005 kingquad quadmatic IRS 700, Its like brand new and has only 600km on it.
I took it out today in the snow and mud and the few times I got stuck I would put the quad into reverse and its doesnt run right, its sputters and spits and hads no power,
Also I would engage the diffrential lock by the 4x4 button and it would do the same thing, no power and not seem to run right.

In 4x4 high and low and 2 wheel the quad runs great, nice and crisp and clean, is there something that I have to do that I am unaware of, I noticed a overdrive button on the left halde bar, I tried it a few times and it didnt seem to do anything at all or light up anything on the dash.
Any tips or help would be greatky appreciated.
Thanks

 

That's the built in limiters.
Push on the grey button and hold, and you get a bit better performance in low lock and reverse, but not 100%

Look for a site named Nyrocs for the cure.
