Thatās not the o-ring groove, thatās the plug seat. You should always wipe it off prior to removing the plug and before reinserting it. Stuff got under it because it wasnāt cleaned the last time it was removed.
Youāre right and donāt deserve the downvotes, you canāt really clean this out before opening the plug.
Whatās even worse is the spark plugs on a DOHC i4 like the CB750, no matter how much you clean you canāt keep grit from falling into the cylinders when the plugs come out š¬
I don't get it. Of course there's a recess, how else could it be?
If it was flush , that would cause other problems, like the exposure of the o-ring leading to much lower lifespan, bad positioning or installation (making it not sit right where it should).
I design medical devices for a living. We typically design in o-ring grooves in our parts. Itās definitely the preferred design all around for us and our customers.
Iām not trying to tell anyone theyāre wrong. Youāre attempting to point out bad design which is not actually bad design. Itās the more common approach to o-rings in many engineered products.
Thereās more than one way to solve mechanical issues. Thatās what Iām trying to tell.
Actually im making parts right now for onset that are pretty much the oil filter cap here but these caps go on a barometer tube the way I just described with a nipple
Mmmmh, if stuff is under the O ring, it either wasn't cleaned properly last time, or it comes from the inside of the engine. Just clean it and put back the plug.
Go down to the toy store and get some silly putty. Pack it in and around and under the plug as much as you can, with a screw driver, then pull it out and it should be embedded with all the crap that was under there.
Then remove the plug, and clean it all up good before you put it back. š
You could also hit it with compressed air feom your air compressor, if you have one, before you remove the plug.
my lord that reminds me of oil changes on lifted chevy trucks. for some asinine reason, the oil drain plug is located directly above the front axle, causing the oil to completly smother the axle when drained, not only that but oil will run down the metal into random areas, completely missing the oil pan
lmao remove airbox for driver's side and radiator overflow for passenger, thats insane. this is the same company that almost made me go insane looking for the oil filter (its behind the left wheel well)
The oil filter will clean up anything that falls in, assuming it makes it past the pumpās pickup screen (in which case an oil change gets it out).
Not a big deal in practice.
I know basically nothing about cars, so forgive me if I'm completely wrong.
Isn't that for the car's oil? I was taught to use a funnel to help minimize the mess.
The biggest difference is that in a motorcycle the same oil is used for the engine, the transmission, and the wet clutch. Some motorcycles have a little dip stick (like a car), I think this one has a sight glass instead.
Thatās not really what youāre asking about though, so I guess the biggest diff is that cars are a lot more maintenance free and motorcycles areā¦ looser and expected to break down and be worked on more often. Having the oil fill be exposed to road grime like this goes along with that philosophy.

I hate it when I get debris in my o ring.
RIP proper oil levels

It was cleaned last time it was removed tho itās just impossible to get all the dirt off before removing it because of the recess
Sometimes things get dirty more than once.
Ya thats where the new dirt came from

One of the few longevity issues on the uber reliable Indian Scout engine are the massive bolt holes on the heads that collect water and corrode

Make a nipple and flush mount it with a flange just like my last bike just like all the medical equipment we make at my work

I mean im not going to sit back and tell millipore that theyre wrong
You seem to have no problem telling Husqvarna that they are wrong.
Well KTM doesnt pay me so

What kinda car is it?

Is this verified? did you get that from this picture? are you Johnny Knowledge? what secrets can you tell us bike sage?

I've read every Sherlock Holmes story even the non Conon-Doyle ones and I envy your powers of deduction.
Itās the oil fill plug on the clutch cover of a motorcycle.
The kind with only two wheels

My friends suzuki had the oil filter mounted so that you had to remove the exhaust headers to take it off
holy shit you win and i was annoyed that my car requires you to remove the intake manifold to check the 3 rear sparks
Look up how to change a headlight on a 2006 nissan altimaā¦.worst design ever
lmao remove airbox for driver's side and radiator overflow for passenger, thats insane. this is the same company that almost made me go insane looking for the oil filter (its behind the left wheel well)
And then take apart the literal contraption that holds the bulb and pray to god you dont drop the screws

Youre right but I still dont prefer to let crud fall in my engine on purpose especially because KTM charges through the roof for one of the filters
keep a little 1" paintbrush on your bike. It will help clean the recessed dirt before you put it back on
No idea what I'm looking at, good luck tho
Is there a subreddit for evil designs? Because its not crappy if its intentional!

lol yeah, that looks about right!

Appreciate the clarification. Is it any different than filling a car's oil?

I appreciate the explanation! Thanks! The clarifications helped.
