I have an '03 Predator and have a question on the front brakes. Some times I have to pump the front brakes once or twice to get an acceptable pressure "feel" to the lever when stopping. When moving and you pull the front brake lever the lever pulsates. What would cause that? (It doesn't matter if you are going slow or fast when it pulsates btw.)

The pulsating that you're feeling is because your one or both of your discs are likely warped. If they are warped enough they can push the pads back in to the caliper resulting in you having to pump the brakes. Or, you also have air in the system which is making it spongy.
I kind of figured that there might be some air in the lines, but the weird thing about that is that it doesn't always do that. As far as the warped rotors, that is not what I was hoping to hear... $$$
