I have a 2017 ZForce 800 with 800 miles on it. My machine won’t go faster than 45 miles per hour. Once it gets to 45 it sputters. I had it at a shop and they couldn’t find anything wrong but did not look at the clutch or drive belt ( that would have been a 3-4 hour job at $100 per hour) Would a bad drive belt or clutch cause this problem? Has anyone else experienced this?

Do this first: Switch the odometer to Tach so you can see the RPMs. Then go out in high range and take it up until it starts sputtering and get a read. If it is somewhere above 7300 rpm, then it can be the limiter and could be clutch or belt related. If not..its something else like fuel pressure, timing,valves tight, intake restriction...ect.

Good stuff. It might be useful too, to see if the same applies in low range, does it start the sputtering and failure to go faster at 20 MPH when in low?
And does pressing the override switch change anything?

Good point. Although the max-RPM limiter isn't effected by the override, the diff-loc is. And the reverse limiter is governed by RPM not speed I believe, so one of those can be in effect. Is there any extra lights on in the dash?
