So I picked up a jug of oil from Wally World and it slipped off the pillion on the way home. Of course the jug was punctured by sliding friction (a gallon of milk suffered the same fate and lived  ) so I wrapped it up in the plastic bag best I could and took off the rest of the way home about a mile away.Of course the bag didn't do jack poo poo and I got oil all over the rear end of the bike. I sprayed an entire can of brake cleaner on the rear rotor to get it cleaned up and wiped off the tire best I could, then did a "burnout" on a bit of dirt road down the street to try and scrub the rest of the oil off. How hosed am I if I get down to the last two inches of tire edge? I did some right-hand circles to just try and see where the limit was and it felt okay but I want to ask here. I'm gonna have a go at the tire when I attack the tail with Dawn and a nice bristle brush, that oughta work, right?

If Dawn can get oil off a penguin, it ought to work for a tire.

Dawn or simple green will clean it up alright, but, uh, rinse that poo poo real good.

My exhaust pipes are rather rusty (mufflers are fine though). My mechanic friend recommended I sand it down a bit, then do one of two things: 1) wrap them 2) paint them with high-temp automotive paint Is one better than the other / are their pros/cons to each? or are they both fine and it's a matter of personal aesthetic? Also what's a cool color for pipes on an otherwise black/silver biek

It's magic and far less of a pain than electrolysis. Even if you can only afford a little of it and have to keep moving the pipes around in the liquid to get it all off, it's still ten times easier than electrolysis (I've done both and will never go back). High temperature paint is a better choice than wrap for the stated reasons. If you want to remove the rust mechanically, use a wire wheel, not sandpaper. Wear a respirator.

I recently bought a brass wire wheel to do just that. Brass is softer than steel/chrome and better for not destroying the surface underneath the rust. Why do exhausts always corrode into a martian surface stucco.

I was wondering how to shine my exhaust up again... Once I go over it with a brass wire wheel, is there anything I can do to tint the metal blue?

Get it good and hot. Somewhere around 600 degrees F is the temperature that steel quenches blue IIRC.

So I did something stupid today. At least, thinking about it with any sort of reason and intelligence, it certainly seems stupid. What I'm here to ask is: how stupid? Rode all day today. Had a blast. Put a little over 200 miles on her. Got home, and decided to wash my bike. I'm sure you can guess here, but, yeah, I hosed down my hot bike with cool water, like a minute after having been riding it. Talk to me, CA.

I mean, don't dirt riders do ice cold water crossings all the time with super hot bikes? What happens when you are riding on the highway, hot bike, and suddenly hit a rainstorm? You are fine.

Hmmm... very true. The rainstorm on a hot bike rings especially true. Still, my mind can't really relax cause I'm thinking I'm rapidly cooling super heated metal, and that doesn't seem especially good for the metal.

Yeah, my first reaction was "uhh" but bikes are designed for that sort of thing, and I'm sure the water you sprayed on heated up faster than it could rapidly and dangerously change the temperature of the metal it touched. Like I said, adventure riders regularly take really hot bikes directly into ice cold streams, sometimes submerging the engine completely in an instant, and are fine. Watch Z3n show up and break down the various metallurgy used in bikes of different nationalities throughout the years, and their individual stress quotients.

The Bananana posted:Talk to me, CA. Meh, who cares. Unless you somehow sprayed it directly onto the exhaust valves or something you won't have caused any damage. I don't think any of the external parts of the engine get hot enough to really experience serious thermal shock just from cool water. Maybe the exhaust headers, but they're just metal tubes and not under any stress. Check to make sure the electronics and air filter(s) are still dry, and wipe up any puddles that might sit and cause rust.

Does powder coating even work on exhaust pipes? It's not a paint...it's a plastic coating that they apply as a powder, electrostatically, and then bake in an oven so it melts and fuses with the surface. I don't know if there's some sort of chemical curing process involved, but an exhaust manifold can definitely get hotter than the powder coating oven. It might just melt right back off. Has anyone seen powder coated exhaust pipes before? (The black matte coating you see on Harley exhausts sometimes is a ceramic coat of some kind, like enamel. I don't know much about that.)

I suppose, as long as it's still relatively clear. Although I don't know how much of the "turning sewage color" brake fluid does is a result of dirt, or moisture over time. 4 days though, I would definitely have another go at it. A year, I'd be like, "ummmmm...... it's clear....OK."

its hygroscopic because its a type of alcohol. 4 days is fine. If you don't have a power bleeder manually bleed the master using the banjo bolt. Z3n showed everyone this handy trick a few weekends ago.

Nice, thanks. I've got a hand vacuum, which speeds thing a up a bit. I sucked brake fluid into it last time, though, here's hoping it hasn't destroyed the vacuum capabilities.

I would still use it after 4 days. I wouldn't after a few weeks, though.

That reminds me that I've got an old bottle of DOT4 that I used on the Ninjer. What do I do with old brake fluid? I could give it to the Pete's Auto next door to work, but I'm worried they're going to just stick it on a shelf and use it in an old Polish lady's car.

I deliver it at the local recycling center which accepts hazardous waste for free, but then I live in a good country that has those.

A lot of states allow it to be mixed with used oil, which is what I've done in the past since it's always a pretty small amount. I typically just dump it into the container full of oil that I"m taking to O'Reilly. You can also pour it into a pan of oil eater/kitty litter, let it evaporate, and then trash the saturated litter. I think that's technically legal since it falls under household waste. Not especially environmentally responsible.

I take my oil to AutoZone and they always make me go into the back and dump it into this big metal box. I don't know what happens with other stuff though, if it goes into that box too or not.
