The magnetic drain plug probably has some value. I look for aluminum or copper colored particles in the oil when I drain it, neither metal would be attracted to a magnet. So............If the steel parts were wearing out in the motor I think the particles would be so small even the magnet may not get them.

Which of the CX/GL models have a sump???


I know the 650 motors have a "sump" (oil pan)

All motors that do not have a separate oil tank have a "Wet sump" where the oil is sitting when you check it.

Those with a tank, are called a "dry sump" motor.

I´ve fitted magnetic drain plugs on a couple of mine.



They never seem to catch anything, which is a good thing. Those small alu fragments you´ll see at the bottom of the oil drain pan, if you have a worn / slapping chain, won´t stick to the magnet.



A normal (non magnetic) drain plug will do its job just as fine.



Sture

Magnetic plugs are a great way to catch early signs of motor transmition failure. Most of the steel particles are from ball bearings and gears. The engine itself has just a few steel parts (cam and rockers) rubbing together and if those start to go its time for rebuild.

That is true, and like Bandit says we tend take care of the bikes after we rebuild them. So the "wear and tear" won't be as ugly as it WAS before...
