I recently bought a 94 polaris 400. When would put into forward or reverse and try to go it would make clicking or grindin noise so wold just go to neutral and back in gear and it would go fine. Well now when I put in any gear it will go slow but if I try to get on it at all it starts grindng likes it not in gear but shifter don't kick out of gear. This dam thing has like 3 or 4 drive chains but it's not those slipping. I am confident I can fix it just need to know what part is causing this or where to look first. When I tried to put back on the pallet where I park it I couldn't even make it on to it it would just grind whenever I go past quarter throttle so had to push it. I just hope it not to late and gears got screwed up. Any help would be appreciated. It does this in 2 wheel drive prob will in 4 wheel to but not gonna find out. Do not that grinding noise it makes. Any help would be appreciated.
