So after alot of research ive learned my bike is a "wasted spark" system........ so correct me if im wrong. In layman's terms it pretty much means that when the piston is on the exhaust stroke the second spark plug in the head fires for nothing? if this i so could i get away with running only the two spark plugs that actually do something. and if so how do i determine which plugs they are. im not very mechanically inclined and im learning as i go with this new build so forgive me if my questions seem ridiculous. its a 1985 honda shadow vt500c....
