Water dripping from the exhaust

[BrianDubbs]

It looks like under the back of the seat at the joint between the muffler/rear section of exhaust system, water drips everytime i start the bike. The weather is a little cold right now, is that a factor?

perhaps just a tighten? i dont like water inside the bike!!

 

[MarinaFazer]

sounds like condensation to me...like cars drip out the exhaust too

 

[reiobard]

my vote for condensation, no worries. just don't start the bike and then shut it off before it is completely warm, once hot the exhaust just evaporates the water. If you shut it off before it is hot the water just sits in there and can cause rust.

sounds like a case of "You started it...you ride it" !!! not too shabby :rockon:

Condensation.

haha brilliant, i remember that clip! one of the best responses i have ever gotten on a forum!

I figured it was water, maybe ill make sure everything is tightened up and just ride!!!!

Wipe it with your finger and smell it. If it doesn't smell like gasoline or coolant, you're good.
But like everyone said, it's condensation. The only time I don't get it is when I start my bike on a 100 degree day, because the water already evaporated from the heat.

I asked the same question to my dealer a couple days ago. He said that it is indeed condensation. And he also said that most exhausts do have small holes to let it go out because otherwise your exhaust can rust.

Check your air conditioner...:squid:

im going to revive the dead here, mine does the same, but it will also white smoke i am told from those following me, is this steam,?i cant tell as i am riding, and again i am a worrier, so in my mind this is connected to the blow by (which may be normal, i dont know) which is not good

just a reminder folks, first bike, so got be too hard on me:Flash:

How cold is it where you live? During the winter months you can ALWAYS see my exhaust. I think it just has to do with some magical qualities of hot air hitting cold air and making vapor. I could be wrong.

Usually it will all evaporate by the time the bike warms up.
If it does it constantly while riding at running temperature on a warm day, then it's possible you have coolant in your exhaust stream, which is usually caused by a blown headgasket.

Just something to consider.

Yes that's true. Same reason you see steam coming from storm drains and manhole covers when it's really cold.

well the water dripping is clear, coolant is brown:ban: (its on my list:BLAA so i dont think its coolant, its been around 70 here so i guess ill wait until it warms up:thumbup:


speaking of coolant, do i just use regular ethylene glycol coolant?

 

[soupflakes]

Hmmm, 70? I would imagine you shouldn't be able to see your exhaust once it warms up at that temperature. I was talking about the teens and twenties that I've been riding in.

 

[FinalImpact]

Its more about the humidity than the temperature. The engine is big old air compressor. At 12:1 you're compressing the vapor in the air and condensing it. At 50% humidity its actually a good deal of water in the air. Once it comes out of the pipe its free to expand again so it basically looks like steam. As the engine warms it pulls the moisture out of the air and burns it.

You might also notice the bike makes good power on high humidity days when your close to sea level. :thumbup:

 

[red_rock_beetle]

same principal as water injecting a turbocharged car?

1. Your coolant is brown? uhh wtf?
2. It doesn't matter what color it is, when it's burned you get a white smoke.

The easiest way to tell is to check your coolant level. If it stays the same and you're not refilling it all the time, then it's probably not that.

All coolant is basically ethylene glycol, but you need to use a 50/50 mix with DISTILLED water, or you can buy the 50/50 premix, but be sure to FLUSH your coolant completely if changing brand/type.

might do that tomorrow, its supposed to be rainy and nasty so ill flush this thing and fill it properly with the green stuff:thumbup:
