I have 45 hours on my RTV500 and will be doing my 50 hour service soon, if I don’t scrap it first. I know this whole thing sounds a little redneck, but, on a hill, my RTV500 will not “downshift”, as it runs out of power, I just continue to release the throttle-servo controller until I am down to a fast walking speed. When the unit was new, I did seem to get just a little “downshift”, but now, nothing. I have lots of power at “walking speed”, I just cannot achieve higher RPMs unless I am going downhill. So yesterday, I removed my bench seat, attached a ¼ inch drive socked with a long extension to the end of the Servo Adjustment Screw and removed my bench seat so I could attempt a Servo adjustment while on the move. I made several runs at the same hill, first while holding wide open throttle, adjusting the screw both in and out with no “downshift”. My next run, I released the throttle to approx. ¾, adjusting while on the move, still no “downshift” and again, the same run at ½ throttle, still no change. Is there any hope for this unit or is it time to move on to something else? JH
