Long time lurker. First time poster.
I have a "no spark" situation. I just purchased a 1978 xs650 special. Rode it for a couple of days. Now no start.
I checked the rotor. Has strong magnetism turned on, residual when turned off.
I tested for spark. None. I checked the resistance of the spark cable against the engine block and it read 18k. I also checked the primary ignition coils and they read 6.3 ohm. I checked the secondary coils and they both ready 9.3k. All seem high from what I ready (5k for boot, 3.9 for primary and 8k for secondary). I also noticed that the spark cable is stranded copper wire when I'm assuming its suppose to be solid...?
Should I just put in new coils, cables and boots? If so any suggestions? Want to make the ignition bullet proof as possible for a daily rider.
If it could be something else feel free to point out my ignorance (first bike).
