Hello.guys I jus bought a 98 fourtrax 4x4 guy said the motor was from a 86. He said the kick start was stuck so he took the lever off, But it would starts with the starter. After messing with it a lil i got it started with the starter but when ever I put it in gear u can see the back wheels jump a lil like it went into gear but doesnt move. I jacked it up and when I manually move the wheels with my hand the kick start shaft turns with them. Anybody have any idea why or what's going on or even where I should start on trying to fix it?
