Default 4 wheel drive locked diff

I have a question about riding in 4 wheel drive with locked diff. Whenever I lock the differatials on my Grizz it runs fine up to 20 miles per hour. Once I hit 21 mph, it cuts out and sputters. Almost like there is a rev limiter or governor on it. It has been happening for the last few months. It's not wet, it happens if I drive it up the road, across a field, on a trail, it happens no matter where or when I drive. Perfectly smooth until I reach 21 mph. It never did this in the past, but for the last several months it has been doing this. I put dielectric grease on all connections, but it happens when the machine is perfectly dry. It seems like some type of governor kicks in at 20+ mph.
Any thoughts?

That is exactly what it is, it is a rev limiter so you can't go over 22mph. On your left handle bar is your over ride button, depress that and you can go faster if need be? I don't know why it didn't it in the past but I am guessing you had a bad connection and when you greased it up it ran the way it was suppose to. Do you need to be in diff lock as much as you say? The only time I am is when I am in the snotty mud, most other times is just 2 wheel drive and sometimes just 4x4. There is no need to be in diff lock on a road, field, trail unless they are fairly steep or excessively muddy. Read your manual, it answers all your diff lock questions and more.

Irv's explanation is sopt on!

On the griz you have 2X4 (rear wheels drive) 4X4 (is really 3X4, rear two and front right wheels drive) and lastly 4X4 diff lock (is true 4X4, all 4 wheels turn) in this final mode it's hard to turn, hard on the diffs and tyres and also some strain on the engine!

I have used it 3 times in 2 years for about 5 mins each time!

And I ride tough technical places!

I rarely ever need to lock the differentials, but back in January I was out ice fishing and the snow was deep so I locked the diffs and it helped to get through the deep snow. It was at that time that I noticed the limiter at over 20 mph. Ever since then, each time I go riding, I lock the diffs just to do a quick test to see if it cuts out above 20 mph. I thought there was something wrong with it.
I had used it the previous winter on an ice fishing trip and had the diffs locked but never noticed the limiter. Maybe I just never went above 20 mph during that trip.
I looked in the owners manual and see that it does state the max speed is limited to 22 mph.
Thanks for the info!
