I have a stock 07 Honda GPScape Rubicon. When I start it up the gear indicator just has the two dashes showing like as if it is between gears and the D1, D2, and ESP indicator just blinks. When I put it in forward gear the bike moves just like normal but when I put it in reverse it spits and sputters and acts like it is gonna die, will barely make the bike move. It hasnt been run much just sits in garage with a battery tender on battery waiting for the next snow storm so it can do some plowing. Anybody have an idea where to start looking for problem?
