Is there a spark in my 1974 CT70?

I’m working on cleaning up and fixing my inlaws barn kept 1974 Ct70. It has not been ran in some time but has good compression and is in great shape. I tried starting it up yesterday and noticed there is no spark at the plug.

Is the 1974 CT70 still in good shape?

Is there a bar control Kill Switch on a CT70?

May have to look in the headlight bucket also. The 74 model has bar control kill switch. Remove the flywheel cover, rotate the magneto counter clockwise, and as you reach the “F” mark the points should just start to open. Verify this.

What to do if your bike has no spark?

A good place to start for a barn kept bike is looking under the seat/tank to see if any mice chewed up the wiring harness. On a 74 you do have a blinker relay by/possibly under the tank and is not related to spark issue. If you are referring to the high voltage ignition coil those rarely fail.

What to do if your car has no spark?

Next take a really narrow finger nail file or fine Emory cloth and lightly sand between the contact pads of the points, just to clean up. Check for spark at the plug. Also the plug has to be grounded to the motor to check for spark at the electrode tip. If the points and condenser are bad that would cause 0 spark at the plug. Great info!

Why does my Honda XL not have a spark?

When you jiggle the plug, you are collapsing the field manually and will get a nice big fat blue spark, but only every now and then and only when the plug is being jiggled. I’ve done this to THREE different bikes now, and if I can get this situation, replacing the points and condenser has fixed the spark issue.
