Hi I have just bought a 2009 RZRS for my self and son , just wondered if anybody could help , when the RZR engine is ticking over in gear it creeps forward and when I put my foot on the brake it stops but the belt squeals a little then when I take my foot off the brake it tries too move forward , when I throttle up it takes off smoothly up too top speed , so any adivce would be great , many thanks Dan
