I am in need of help diagnosing a problem. I bought this bike almost a month ago and it was running, not well but running. After figuring out it was running on one cylinder, I cleaned the carbeurator, which was gunned up alot. That didn't do anything so I took another look at compression and spark. Compression was great so I decided to change the coils due to weak spark.
That still did not fix anything. So I started looking for an electrical short, I found a melted connector in the headlight and fixed it. Next when I turned the key on it fried my cdi box. Found another one on ebay and put it on. Instantly fired up and was running on both cylinders. Then I popped a fuse, so I replaced it and started looking for a short. Haven't found one at all.
Is it possible that the ignition is bad itself even if it test good? Any help or advice is appreciated, I'm at a loss at this point.
