I did my first oil change.



Previous owner added a small (1/2" by 3/4") piece of magnetized metal to the oil drain screen cup. Looks like he used an old speaker magnet metal washer/plate and cut it down then bench ground the edges smooth so as not to cut the screen. It was inside the cup (the area towards the outside of the bike).



Sucker had a fair amount of fine grit and one larger piece maybe 1/16th by 1/8th.



So two questions:

Is that normal to have so much metal?

The second question is this....

I didnt open up that upper drain screw or whatever it is that is shown in the oil change sticky to see if I had oil flow. Is there any reason to do so beyond a check? Like to bleed air??

It's just there to verify flow. Call it cheap insurance if something went wrong during oil change. No flow out that screw = seized engine after a few miles of riding. Loosening a screw is better then buying a new top end.



How much grab did that magnet have? Unless it is a magnet made for high temps it will keep getting weaker each time the bike is run.



My magnet had a tiny bit of fine metal goo on it after 1k

I didn't think to test the magnets strength because it seemed to be working well.

I'll keep an eye on it though, thanks.
