hi, i'm new to this forum and i have a question. i can't afford an atv so my neighbor said i can use his grizzly 660 when ever i want. he even gave me a copy of the key. my question is, is there a way to overide the rev limiter while in diff-lock? with the exception of the rev limiter, i love this machine.

 

Yes there is, but it requires a wiring modification. Not a good thing on a bike that does not belong to you.

 

If it is a newer Grizzly there already is an override button below the kill switch. You need to be in Low, Diff Lock and push the button. The speedometer will start making circles and you are ready to hone on it. That is how it is on my 2006 Grizzly
