My 2010 Rancher 420AT is having problems starting from a dead stop. When I’m in first gear and give the bike gas it starts to move slowly with the engine reeving up and then it engages abruptly. This causes the wheels to spin and a jerking motion. The hotter the bike gets, the worse the problem is. The bike does this in both ESP as well as Auto Mode.
I have changed the oil, cleaned radiator to make sure the bike is running cool also the centrifugal clutch drum and all 4 clutch shoe weights. The bike continues to run the same way.
Looking for help of what to try next.
