Liquid Coming from Exhaust

[HotdogMcDraw]

Hi,

Took my 125 out today, first time in a few months and noticed a watery substance at the end of my exhaust. I gave it a wipe and looked dirty and a little rustic, could it be just water stuck in my exhaust after being in storage for a few months? It doesn't smell like petrol or oil so hopefully it is not anything too serious.

It's air cooled by the way so coolant is out of the question. Hopefully it's not piston rings or anything like that as it is riding as it should be with no suspicious noises etc, but if anyone has had a similar experience or knows why let me know.

Much appreciated.

Aye......condensation. Some pipes have a tiny hole underneath - supposedly to let the water out - as it can rot the pipe from the inside after time.

My bet too would be water/condensation.
Best go for a long, quickish run, making sure everything up to temperature.
Then look at it again.

Wow quick reply

Thanks guys, will take it for a long burn tonight and see how it goes from there.

Cheers.

Almost certainly just water.

You can get it even if the bike hasn't been sat for months... my car does it on a daily basis unless its warmer than about 20 degrees air temp.

My bike doesn't seem to do it but perhaps because the silencer and exit is much higher up than the rest of the systems and condensation will drain to the lowest point, whereas on the car the system is pretty much level

When you burn a hydrocarbon you get three things in abundance: carbon dioxide, water and heat (plus a load of stuff in smaller quantities). When you burn a litre of fuel you get around a litre of water vapour created. When the exhaust is cold it acts like a huge condenser and cools the exhaust gases down enough for the water vapour to condense to liquid water. That's why you see plumes of steam from a cold engine on a cold day and it's why water can collect in the exhaust. Once the exhaust has warmed up the water no longer condenses and exits as a gas (which you can't see); any pooled or collected water will also boil away.
