So I know the bike is only a small 2 cyl. and the main thing that alters the sound of an engine is the internal layout. (Amount of valves. Ignition timing. Stroke length compared to the bore ratio...) but I have started getting more and more annoyed with how weak my Cb500F sounds. I know it is a rather weak bike, but i've met plenty of people on 300cc and even 125cc with better, rougher sounding bikes. I have a GPR Furore slipon, wich i regret getting, as the diameter should be bigger to deepen the sound. But lately i have considered getting a full R77 system, but judging by videos, this doesn't seem to make a large difference. Tips to make the bike sound a little louder, and alot more punchy?
