Hello! I just got done tearing my bike apart to put in a kn filter and save some time for when my EJK fuel controller comes in this week. I actually have 2 questions regarding this bike. First, in the posted picture is that the fuel injector? (I'm unfamiliar with single cylinder anything) and secondly, where is the pair valve? I will also Google this in the mean time but if I can get answers quickly that would be great! Thanks a lot!
