Im at a lost why the wheels sit like this in the rear.
i even had an extra right rear axle and it does the same thing. something bent on the frame? i got this quad for 300.00 bucks and it runs great, but it needed bearings and brakes so it didnt have the axles on it when i bought it so i was unable to see how the wheels sat. i believe i can fix it by adjusting the shock hole, that would straighten it up. but i thought i would check here first. thanks

 

I think all with IRS does this. When you start riding the wheels will straighten out. there is nothing wrong with your machine.

 

It's normal - short travel IRS does that.

 

The front suspension has dual a arms, and will keep the wheel perpendicular to the road as the suspension travels up and down. The rear suspension is a diagonal swing axle, as the suspension travels up and down the wheel will rotate about the swing axle pivot point, causing the effect you are seeing.
Kinda like the old V.W. bugs used to. In short, it's normal.
