Question by denis g: How do I bypass a speed limiter on a Yamaha Grizzly 660?
I have a Yamaha Grizzly 660 and I’m not sure why but as soon as I get to 21 mph the revs don’t increase instead the engine just sort of misfires and doesn’t go faster. My second question is why is the diff-lock light always on even when I’m in 2wd my guess is that if diff-lock is on that might limit speed.

You just answered your own question. You diff is engaged. There is no “bypass” for the rev limiter, and this isnt any kind of solution to your problem. You need to have the bike serviced, tuned up, and probably from what it sounds like, a carb cleaning and adjustment.
