Does anyone know what size the oil drain plug is? Or which ones for other bikes are compatible? Bonus to find one predrilled for safety wire. I can't seem to find this info by Google search.
Thanks!

use the ruckus magnetic drain plug

that way you get the benefit of catching metal particles
and even though you have the filter you will still have metal particles every oil change on the magnet
I've been using those for years on all types of bikes always has black fuzz on them

I used the Outlaw Racing M12 x 1.5 x 13 magnetic drain plug from Amazon. Part number is OR2623H and it's $8.95. It fit perfectly, is made out of steel and not aluminum, is drilled for safety wire, and magnet is very powerful!

Mine fit with no problem. Definitely have to use the washer it comes with.
Fox Fader,
That looks like a great solution, but when you say you have to use the washer it comes with, does that mean that when the washer needs to be replaced you will have to order a new bolt and washer assembly or will you just need to find a source for a replacement washer?

You'll just have to replace the washer after several drains.

RE: Crush Washers

I've always been a little conflicted on this topic, let's use spark plugs as a more extreme example.

Many (most?) spark plugs come with a type of crush fitting that allows a user to turn a half or eighth turn after finger tight to properly seat the plug. This accomplishes two things. 1.) Under tooled DIYers can install their own plugs 2.) Increases thread friction in a predictable way. This isn't to say you can't remove said plug to check it's condition or gap, but you would actually need a proper torque wrench the second time around.

If you did re-install a pre-crushed spark plug and followed the instructions on the box it would certainly be over torqued and might get you in trouble. This is because your end point for finger tight is now a solid face instead of a compressible element.

This is to say, when you re-use your crush washer, just treat it as a spacer, it will only compress once.

Personally I don't like crush washers on drain plugs because I know they are good to re-use with a bit of common sense (or arguably not necessary in the first place) but being the goodie-two-shoes that I am I install a fresh one each time... because the manual says so!

Thoughts?

Cheers for all the suggestions, I picked up the Outlaw one. The removable magnet design is really clever but backing the magnet out seems like more work than just grabbing the filings with the rag that's invariably already in my hand. =P Plus I'm cheap.

For a drain plug? You bet!

For spark plugs? I'd disagree.

I'm just saying I don't like crush washers on drain plugs because they are completely unnecessary but my OCD forces me to replace them anyway...

I'm used to my Euro cars, parts shopping for a Japanese vehicle is a weird mix of "super nice custom" and "really cheap Chinese knock offs"

I disagree. The oil drain bolt is one of the most important fasteners on the bike. It's one that needs to be removable, but if it leaks or comes out on it's own, you are going to have a bad day.



I replace my crush washer with every oil change. I have a baggie of about 100 crush washers so I don't have to buy one with every filter. I also safety wire the drain bolt on every bike.... Even on the wife's crusier.

I replace drain plug washer every time I drain oil on every vehicle I own. Go on amazon. You can buy copper washers in various sizes. I spent like 7 bucks once and now I have like 30 of different sizes hanging on a nail in a wall in my garage. I just grab one off the nail every time I remove the drain plug. This is one of those things where it is so dirt cheap... and even though you could reuse one... why would you? They cost like 12 cents a piece not the hill to die on IMO.

I like this idea.

What size copper washer do you buy to use with the oil drain plug?

What size crush washer do you use with the sparkplug? (Now that I have a non-OEM exhaust, and plan possible further changes, I find myself pulling out the sparkplug more frequently than for mere replacement with a new plug that comes with a new crush washer)

Unless the plug came with a washer on it I wouldn't add one as that would change the location of the spark in the chamber ever so slightly. I was referencing the NGK style built in crush feature. Haven't pulled the Z's plug yet so my apologies for being clueless.

The OEM NGK sparkplug on the Z125, like most (all?) sparkplugs, comes with a crush washer from the factory.

After one use though, it is permanently already crushed, which is why I am asking where I can get a supply of properly sized crush washers so I can use a new one each time I put the sparkplug back in after checking its colour and overall condition.
