I made my own magnetic drain plug using a high strength rare earth neodymium cylinder magnet from K&J Magnetics.



The results aren't as spectacular as general search photos on the internet often show, but this only has about 200km on it. The oil filter was new btw.

At least there's a little bit of metallic goo that won't be abrading the internal engine parts any more

 

I fitted a magnetic plug to my (now my sons) KLX250s after the rebuild to catch and steel particles that may have been missed in the cleaning after the Balance bearing failure.
Did an oil change at 100km and found two or three steel particles on plug and some aluminium particles in filter.
100km after oil change we laid the bike down on the grass (left side down) and removed plug and there was a little goo as you show in you picture which I put down to bearings and rings bedding in.
it should be noted that the oil filter is after the pump and the magnetic plug stops (most not all) steel particle from being pumped through it, so the pump runs in unfiltered oil.

 

Mine's hanging on the wall waiting for my next oil change.

 

I'm a pretty firm believer in using a magnetic drain plug, (as well as a FilterMag: FilterMAG: Magnetic Oil Filters finish the Job Your Filter Started. ) I've made one for the Rover in a similar manner. Plenty of evidence that it's the fine metallic grit that abrades the cylinders. I'd recommend a by-pass oil filter, too; particularly if you're running a V-8 pickup or 4x4. The more grit you can keep out of the pathway, the better. Lots of chatter about "extended drain intervals" which I think is idiotic. What you might save on oil expense, will only COST you on cylinder/engine wear!
OK, I'll shut up.

 

I just slapped an old computer hard drive magnet onto my filter. It makes the whole filter into a giant "magnetic drain plug"! When I change the oil, I move the magnet to the new filter. This has worked out great for me...

 

that's a great idea ^^^^
wher did you put the magnet on the filter ?

 

I put it on the outside surface, so I see it when I open the case to change the filter. These magnets are insanely powerful, no ferrous material will get past it!
