400 chain drive: brakes pads brakes squealed every time you used them broken weld on frame ate spark plugs Had to nearly give it away to get rid of it!!! 500 Sportsman: (3) they all shared most of the same problems hard on drive belts undersized screws instead of bolts in the secondary trans pulled out. Had to tear it all apart, drill to bigger size and retap the holes. brakes pads don't last ignition switch steering linkage all wore out in less than 1000 miles brake master cyclinder leaked it's hard to change oil and service them porous aluminum wheels constantly leak air brakes squealed every time used wireing problems in spedo pod plastic racks don't hold up like steel ones do I'm sure there's more, but that's what comes to mind right now. Ever notice all that plastic on top of those sportsmans????? ????? My neighbor rolled his sportsman over, it broke (among other things) the spedo pod, racks, plastic brake master cyclinder, and it never steered right again. He had to truck in home. It cost him over $700.00 to fix all the parts! I rolled my Yamaha 600 Grizzly over even more violently on a hill, and it bent one side of the front steel rack, and broke a bolt on the throttle cable. I drove it home, used a 4' pipe whench to straighten out the rack, and the throttle bolt is still broken, but it's on the job hauling loads every day i need it!!! The steering is still straight and even though i haul loads of rock ect., i'm still on the origional drive belt!! In fact the last time i was at my Yamaha dealer, he had NOT sold even one replacement drive belt for a Grizzly! BTW, the brake master cyclinder is steel on my Yamaha's, not Polaris plastic! That alone shows the lack of engineering on the Polaris', but it's good for parts sales!! Robert
