Does anyone know the width of the oil drain plug (threaded part)? I want to put a magnet on it and want to get the right size. Thanks!

10 mm / 1.5 is what mine says...so, 10 mm...looks about right looking at my spare plug

You have a spare plug, even better. Is the end completely smoothed or raised where the threads end? Can you measure the inside surface less the threads for me. Thanks.

exactly 5mm inside center without thread..from measuring with a ruler...

$35.00???? That is one expensive drain plug. But if it saves your engine, worth every penny.

I bought a rare earth magnet that will sit on top of the stock plug for $1.30.

I stuck a magnet salvaged out of an old computer hard drive (free) onto the metal part of my oil filter. It seems to work very well there, and no chance of it getting loose inside the engine!

I'm rebuilding my KLX after a balance shaft bearing failure, one thing I noticed is the oil pump is damaged due to the metal particles that fitted through the brass gauze being pump though the motor, a magnetic sump plug will not stop all the particles but will give you a good indication that something is not right at oil change time, the magnet in the filter will catch the metal that the filter would have caught anyway.

I started doing this on my first oil change - brand new engine (80 miles at first oil change). When I pulled the factory filter, I notices sparkly flecks in the paper folds. That's when I got the idea to slap a magnet onto the filter. I've done 2 more oil changes since putting the magnet on the filter. No more flecks in the paper - they're caught before they get to it. When I change the oil, I just wipe off any metal stuck to the magnet and stick it back onto the new filter. This way I STILL get an indication of the amount of metal pumping through the system, AND it stops it before it cycles through a second time... (and, it's free).
Think about it:
I can't imagine the drain plug magnets do anything at all, except for catching a few suspended particles when the bike is PARKED. With the engine running, only a tiny fraction of the oil will be passing anywhere near the oil plug. The engine would have to be stopped for anything to settle close enough to the drain plug for the magnet to attract the particles, and even then, any particles beyond the field of the magnet will remain in the oil.
If your oil pump was damaged by metal particles as you say it was, then your oil filter was NOT doing its job! I'm guessing it was probably a K&N or some other non-paper (i.e. metal mesh "reusable") oil filter.
