2008 rhino 700 stays in low range even when shifter is in high revers light stays on and speedometer inop

It might be the spark plugs or plug , but it looks like a fuel, pressure, filter,and injector problems Changing the plug is really easy. If it still occurs , change out fuel and then check the fuel pressures.

Sounds like you losing power in run position. Check ignition switch to be sure power is staying on in run position.

I take help from online websites th at have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... rest is up to u.. U can also get free manuals

your shift linkage could be out of adjustment. the two rods that run to your transmission. try disconnecting one and see if it shift *(without the engine running), then do the same thing for the other. if it shift into high without the low gear shift linkage disconnected, then they are out of adjustment.

It needs to be calibrated, you can't do that at home.

If you are only getting 65lbs of compression, remedying that would be my next move!! .. I have seen some run as low as 85lbs..run very poor too.. but never at 65lbs. You should let the engine turn over for about 5 seconds to get compression level.

Is the water pump operating?

sounds like you are hitting the rev limiter. If it launches that hard im guessing you have a belt or clutch issue.
