So, I just bought my first HD I bought the 500. I moved up from a Kawasaki Eliminator 125cc, so the 500 feels way more powerful than what I was riding. I am hearing loud popping from the pipes - I think it's because I may be in too high of a gear? So, for this newbie HD rider, can someone give me a step by step on how to shift and when to shift? Even if I follow what the manual says I still get that popping sound. Thanks in advance for your input.
