Maintenance for Points Ignition Systems
Older motorcycles that still run points ignition systems can sometimes be a pain the behind.
The slotted crosshead screws that locate points and/or back plates are often badly damaged and resist all attempts to loosen impact driver used without a hammer normally sorts the problem.
Lean on the impact driver had with the head perpendicular to the back plate and turn; amazingly this will almost always work.
Either replace the damaged screws with similar or, better still, invest in some decent quality socket headed screws to make the job easier next time.
Always ensure the replacement screws are the correct/same length or trim to suit as you really don’t want their ends hitting the rotor behind the back plate!
