Only firing on one cylinder
My grandfather and I are working on an old honda CB500T barn find. It's got a lot of work left before It'll be good enough to ride, but for the time being the motor is the main concern.
Right now the motor turns over and runs, but only on the left side cylinder. The right side isn't getting a spark. A spark tester as well as removing the plug and running it outside of the cylinder proved this. I thought it was either the ignition coil or the points. I checked the coils and it seemed the right side coil might have had a connection break somewhere in it. I replaced it with another set of ignition coils from a bike we had upstairs (might have been the cb450?), which i checked and all the connections were good, yet it still only ran on the left cylinder.
After this i decided to check the points. I had looked them over before and, with the origional coils, I noticed that the point for the right cylinder didn't spark at all. With the coils i pulled off the other bike installed, both points sparked, but still no firing on the right cylinder. The wires coming from the points didnt seem to have a breaks in them (ill check to be 100% sure later).
I made sure all of the connecters were good and plugged in, so that wasn't the problem.
The only things that I could think of would be either that the right side plug is bad (I'll check that later by switching the plugs), or that somewhere between the points and coils, the right side wire has a break somewhere in it.
Any ideas as to whats causing it to only run on one cylinder?
