can the counter balance shafts be removed on a 1100 blackbird for in creased performance . what is the best bang for the buck performance wise for these motors. also are these motors very heavy or not.

 

I don't know much about those motors, but I would say no to removing the ballance shaft. Its there for a reason, and its not just to limit vibration to the rider, it will surely help limit damaging vibrations to other parts of the engine.

i don't think they are any heavier than any other 1100cc engine. But keep in mind the bike was designed to have a high top speed and be a sport touring bike, not a lightweight sportbike. So weight savings were not part of design. Aerodynamics and comfort were much higher on the priority list.

As far as performance. It depends on your goals and your wallet. Turbo, cams, exhaust.... if your only interested in getting more power down, a sprocket change is the best bang for the buck for performance.
