Ok this is strange. The other day on the way home my bike started running rough. Got home and found it was only running on one cylinder. The left exhaust was really hot and the right exhaust was warm to touch.
I re checked everything Had spark on both plugs, the condenser was good I reset the points to be exact and still running rough. Grab the timing light and hooked up left side and the timing light came on and timing was right on... hooked up the right cylinder and the timing light would not come on...
Not knowing what to do I took off and rechecked the right spark plug and there was spark. But then I decided to put an older plug and sure enough the timing light worked and the bike fired up and ran like normal.
So to double check I put the right plug on to the left side and there was spark put no timing light. Definitely a bad plug that looked normal and did spark but not good enough for the bike.
Moral of this story is that plugs may not necessarily be good even though they spark.
Anyone had this experience??
