Hello, I'd just bought a Rancher and never yet owned a Honda ATV so I don't know if how Honda drive like that. The Rancher starts good and when push the button to either 1st gear or Reverse it jolts a little (may be idle too high). All the gears change ok when riding only wait for the rpm slow down or the Rancher would dies. Does not matter if up shift or down shift. What causing that?
