I got a 2004 Raptor 660. On hard accell it pulls to the left. Any idea why? I check air pressure and they are the same L&R.

 

check your compression and/or rebound adjustment if equipped!!!

 

Somehow I doubt your shocks have magically gone out of sync. I havent seen the stockers adjust on their own.

Check your tire pressure and front end alignment. You may have a bent tie rod, a low tire, or a tweaked steering stem or handle bar.

 

I don't understand. What commpression, rebound eqp.

 

When you hit the gas the front wheels are in the air. Something in the rear is pushing left. Tire psi is the same. 3.5 psi.

 

Make sure that the rear axle is tight on the bearings. If it comes loose even a little, on hard accel., the chain will pull on the axle and make it pull to the left.

 

That sounds like that could be it. Are you talking about the 2 bolts that run through the rear center section?

 

Yes, thats what he's referring to.

You want to make sure that both bolts are exactly the same number of threads into the bearing carrier and that the lock nuts are tight too.

 

If they are not, than it will angle the rear axles correct? Making it go left.

 

yes
