it does it at different times like today it did it while i was accelrerating but it was the first time but it mostly does it when i am just cruzing along to describe it best it feels like when you are not giving enough gas for the gear you are in. any cles what it might be.

It could be a couple of things. When I asked "when" does it do it, I meant more like shortly after startup or after having been ridden for a while, or when it's hot out, or when it's cold out, or...
If it is shortly after startup and/or when it's cold out, then (according to my stealership's mechanics) you aren't warming it up enough. They say that the '07 FI system needs 5 minutes of warmup in order to run correctly in cooler weather, and the bucking and kicking is perfectly normal for inadequate warm up. If it does it at other times, my first guess would be that you are in the wrong gear for the speed you are going, and lugging the engine. Sportster engines like to wind up a bit, and really aren't happy below about 2,500 RPM, especially the FI engines. If neither of these is the case, look for a clogged fuel filter, then check that your fuel pickup hasn't shifted. If all that's good, I'm out of ideas.
