Hi,
I'm having an issue with my 2014 Polaris Sportsman 570.

It doesn't rev enough to go more than 15 MPH. Pushing the Overdrive button helps, but obviously not a solution. It's like it hitting a rev limit but starting at low revs.

Instrument cluster is not working since a while now, so no info I can get from the screen.

Cleaned the tank, fuel line, inyector, check spark plug and noting visually wrong.

Anyone knows what the issue could be?

I'm not an expert, but according to service manual ohms between y1, Y2 and Y3 should be 0.19 ohms +/-15%

Using multimeter in 200M ohms scale is giving me the following:
Y1 a y2 = 4.4
Y1 a y3= 39.1
Y2 a y3 = 38

Each one individually grounded infinity.
Could this be the answer?

The dealer mentioned today that it can be in a "auto limited mode" if service is not reset on dash... as I don't have a working one, he mentions He can't do anything... mmmm suspicious

Check the AC voltage on all three legs 1-2, 2-3 and 3-1 both disconnected from the rec/reg and connected up to 3000 rpm - should be appx 25 to 100 open circuit and 25 to 90 closed circuit.
