You mentioned it either stalls or takes off. Does it idle ok? To build on what others have said, the pilot jet or slide cut away could be way off and you are feeling a transition from a rich mixture to a proper mixture and that will enhance the feel of the "hit".

If you open your ignition cover do you see oil or smell gas? Does your trans oil smell like gas? Either will point you toward bad crank seals. The older bikes used seals that were not compatible with fuels with high levels of alcohol and fail. This will also mess with your AF mixture and can result in odd operation like you are experiencing.
It looks like it has one regular gasket under the cylinder.
