The Big Money
If you are fortunate enough to still have cash in your pocket after all the previously mentioned services and updates there are two more areas of improvement to consider that will have a drastic impact on your riding experience. By changing a few key components to high quality aftermarket parts you can often increase the performance of an older motorcycle to a higher level than that of the new model year.
When it comes to making more power, the engine on your motorcycle should be considered a big air pump. The more air you can move through the engine, the more fuel you can add to that air, and the more power you will produce. Everyone is familiar with the fact that motorcycles have to meet more stringent pollutant emissions requirements every few years but most folks don’t realize that your motorcycle also has to meet SOUND emission tests as well.
Sound emission effects more than just the muffler on your bike, manufacturers design every part of the intake and exhaust system to act like a labyrinth to bounce and absorb sound waves. The intake pulses of an engine are routed through complicated air boxes with small and oddly placed air filters while the exhaust pulses are pressed through a series of platinum screens and then bounced through a series of chambers and absorption material. In many cases, changes to the intake and exhaust systems can increase engine performance, reliability, serviceability, and also reduce weight.
