A few weeks ago I picked up a nice gold 72 cb750 at an estate auction for $700. I usually chop old jap bikes but this one is too complete and nice to cut up. Ive had a few old beater sohc but they always ran. I need some help with this one.
1. No spark!
Th starter button was missing from the controls so I bought a new one from 4into1.i replaced it and now I have all my lights but when I hit the starter nothing happens. No clicks nothing. I have it in nuetral.
I can jump the startermotor at the solenoid but even though the engine is turning I get no spark. I do have some points and condensors to put in but I would like to get the starter sorted out.
When the engine is turning over the points spark erratically.even if its not timed right shouldnt I get a spark at the plug?
I was told to run a jumper wire from the coil where it goes to the points and ground it to the frame to see if I get a spark to test the coil. The jumper cable sparks at the frame not at the plug. So there is ppwer running through the coil but its not sparking at the plug. Does that mean anything? Just trying to knock things out one by one.
Here she is
