Seriously, couldn't they just extend the tube a bit so it overhangs the exhaust pipe???

This is super common with motorcycles. The motor should be warm, but not ignite-the-oil hot during an oil change. Clean it up with some brake cleaner.

Use a piece of aluminum foil to make a little drain to direct the oil over the exhaust.

I know that's a solution, but as a solution to bad design it's a little bit "Just wear a rubber glove to stop your oven electrocuting you". Yeah sure, but maybe design it better?

Do you have any idea how much the manufacturer saved in not extending the pipe tho?

Because I have no clue. Probably wurf rite

What they actually probably saved was needing to design a whole separate engine case for each bike in their lineup to match all their exhaust configurations.

The idea of having a little pipe protruding out is a different kind of bad design. Things that poke out from engine cases tend to snag or get punched in during a crash, turning what would be some scrapes on the block into a completely totaled engine.

A genuine question if you would like please, I know you meant warm oil for easy maneuvering (oil moves faster when warm/hot), but what about hot oil? Is it safe to change motorcycle oil after an hour or more ride when the oil might be toi hot?

A co-worker of mine tried adding water to his car reservoir after he just stopped from a long ride, the water was near boiling point and it blowed up on him the moment he opened tha water reservoir (not sure that is the correct name). Can such a thing happens with oil exchange?

Oil doesn't expand and steam like water, so no that won't happen, but hot oil leads to very nasty burns and can melt gloves onto your hands. Most bikes run the oil around 200 degrees. So no it isn't safe to change hot oil. Don't do that.

And, specifically because oil doesn’t boil at those temperatures, it can be at much higher temperature than water can be as a liquid.

We tend to have a mental model of how much damage water can do at its “max” temperature, because liquid water stops existing after a certain temp.

But oil can be so much hotter than that, and still just be a liquid. It’s dangerous in that way, because while a drop of water at near boiling can only do so much damage but a drop of oil can be holding a lot more heat and hence cook a lot more of your flesh before it runs equalizes with the surroundings

No, you should just idle the bike until the temp gauge comes up. Should definitely not be after a long ride.

Foil is a great idea, I'll use that next time.

[–] [email protected] 1 points 10 months ago (1 children)

Plus people know you mean business when you’ve got some foil.

Guy pulls over his car and brings out the the lug wrench, okay fine. He’s gonna change that tire. Let’s hope he doesn’t forget to chock the wheels, but he’s got the idea.

But you see a dude pullin reynolds wrap out of his bags next to a motorcycle on the off-ramp, that’s a serious dude. That’s the kind of dude you give that dude a burger when he walks by. That’s all I’m sayin.

.... I'm going to start carrying foil with me.
