So I was at Coral Pink sand dunes this weekend with my rzrs. I have only had this out a fewtimes since I got it. I was trying climb a few hills there and noticed it bogging down real bad but thought it must be normal. When my friend showed up the next day with his rzrs i tell him to go hit this hill so I can see how his does. Well he shot straight up it with no problem. Mine does just fine on flats or down hill but is horrible up most hills. Not sure where to start looking at this point. Any advise would be appreciated.
