So my girl friend Sand Chick is out driving here new Ace 570 at Dumont and it seems to not be revving up high enough. I was only.seeing about 6250. I am not sure what the rev limiter is set at but seems to be around 7300. Anyway is anyone making adjustable weights for this unit yet? We work on rzr's all the time at our shop but not sure about what these things are using.
