have a 03 600 twin sportsman, the bike pulls hard to the left and when you take your hands off the steering wheel it shimmys real bad. I have orginal tires and rims. do i need new tires and rims? tahnks

 

You have one rear tire taller than the other.

 

check the air pressure in tires and check the alignment.

 

i dont understand what you mean, both tires are the same.

 

Ditto, Also check for loose/worn tie rod ends.

 

you sure that side hub is not engaging the into the awd? you can check for even tire pressure in both tires to make them the same and if thereres no worn parts as mentioned them maybe the tires them selfs might be out of wack. imo
