Engines are air pumps, get more air in, combine that air with the right amount of fuel, burn it and get that stuff and out as effiecently as possible and the engine WILL make more power.
The main restrictions on the 1700's are the exhaust and the intake systems. Reduce restriction in either area and the engine will make more power.
OK, installing a set of slip-ons reduces back pressure (aka restriction) in the exhaust and the engine will make more power. Install a BAK and by reducing the air flow restriction within the intake system the engine will make more power. The installation of a freer-flowing intake on a skoot with stock exhaust will allow the engine to make more power, but the potential power gains of that BAK will be limited by the stock exhaust. In other words you will not get the full benifits and potential of a BAK with the stock exhaust as would be had with a freer flowing exhaust.
SO....if you "need" more power, then a BAK will allow the engine to make more power by gettin more air in. Then we have the necessity of tuning the fuel injection to provide the proper air/fuel ration for best performance.
