I cannot figure this out guys. Last year it was doing the same thing. It starts, idles, and drives slow, but when I give it more throttle it bogs down and won't really open up a go. I put new fuel lines on the motor last year because they were cracked and leaking. I thought that was the problem but apparently there is more to it. I wish I had more specifics to help you guys help me but if you could just give me some ideas I would appreciate it.

Cracked and leaking fuel lines means they were breaking down over time, probably due to the fact they were not designed for use with ethanol fuel and just plain age as well. This also means that chances are good that pieces of the fuel line were probably drawn into the carburetor.

A good cleaning of the carbs is a good place to start.

Have you had the carbs off and cleaned them?
If not, that would be step one, and pay extra attention to the high speed jets.
