Hey guys hows everyone just wanna say thanks for advice in advance. So i bought a 84 gl1200 interstate. Had redo jets in the carbs. Those are doing good ran like a rocket for one trip and ever since i have been battling with it. I have just found out actually that i have no spark on my rear cylinders coming from my left side coil. Test the black and white wire for ground good. The bkue and yellow nothing at all. Trace back to cdi box have continuity all the way to and into box. Now idk what im missing ive tested set of 3 and 4 wires to the left of battery for the stator everything is good there. Im so lost and im about to scrap the bike even though i dont wanna please help.
