A few more tid-bits: The smog pump is just one component that truly messes with your power output. If you are going to remove this component, be prepared to re-jet or move the needle on the carb. If you do this, you may get 3 to 5 horses. If you already have oodles of power like I have, you get larger jumps in power. Frankly, I am flabberghasted that simple things on this bike slow it down so much. Be careful how you re-route the hoses. There is active oil flow in there and it can bleed back to the air box.
