I recently picked up a 1977 Yamaha XS360 and I can't get a spark on it. It has a. Brand new battery and all the connections are good. It has a points ignition system which I'm quite new to, Any suggestions? Thanks.
Points gap...set to specs, timing...points should just begin to open at a predetermined BTDC...usually marked on the points backing plate. Check the points for arcing...they will be black and pitted if they are arcing. This is usually caused by the condenser/capacitor failing. Finally check the plugs/caps/cables/coils.
