Sooooo, I inadvertently left the Uly out, uncovered, and it got drenched in a BIG spring rain. When I go to start her up the next day, there is a sizable amount of water shooting out of the exhaust. My guesstimate is a half gallon or more came pouring from my baby. Idled fine, rode probably 25 miles last night, zero noticeable effects. Any reason for concern? | ||

Which exhaust? Your profile says Drummer. I can't see how much if any water can get into the muffler short of someone putting a garden hose in it, since it would be angled downward when on the sidestand. On my EBR SX I have the secondary exhaust delete, so the main exhaust can has tips that are almost straight up when on the stand and I've not had a problem with water accumulation even when washing the bike. That said I wouldn't really be concerned with it. | ||

My bad. Exhaust is stock. Bike was on a slight downward slope, so hard to see how that much water could have leaked in there. | ||

Maybe a cracked head? These Ulys have been known to leak radiator air into the combustion chamber where it is condensed into water through the catalytic converter process whereby parking it in the rain can fill the muffler and tires with purified drinking water that if strained through a sock can be consumed by your riding buddies when mixed with home brewed alcohol. Your results may vary. | ||

On the other hand, I rode mine in a blistering rainfront last night and left it out to be rained on the rest of the night. Stock muffler seems empty. I'd guess a half gallon of water in there would block the exhaust enough that it would prevent starting. Possibly a lot less looking like a lot more? | ||

"radiator air" makes my brain hurt. | ||

Wow, I can't think how it would get in there either unless the clamps on the down pipes were loose and allowing water to run down the pipes into the muffler. | ||

First, grab a gallon milk jug and fill it halfway with water. Dump it out. Was it REALLY that much? Somehow I doubt it. That would FILL the muffler, and wouldn't run out the pipe, it would shoot out once compression came down the header. Like a garden hose. Was it a stream or a spray/mist? Just for kicks...take that milk jug again, and try and dump the water into the muffler to see a) if it can go in, and b) what it does when you start the bike. Somehow, I'm guessing it was simple condensation from the weather change (obvious humidity), misting out the exhaust a little heavier than usual. Do you hear any exhaust leaks? If you can't hear exhaust coming out, there's nowhere for water to get in... | ||

I haven’t noticed any exhaust leaks, but I’m not sure exactly what to listen for. I assume it would be an obvious hiss or pop. As for the amount of water that came shooting out, it was enough to puddle, roll to the curb, and make a stream 15 yards down the street. I’ll go over the can with a keen eye and ear and check for cracks. | ||

That certainly is a large amount! I don't see how that would be possible but for running down the header pipe and past the clamp. Might get enough clearance when cooled off maybe? | ||

The outlet on a stock Uly exhaust actually comes out high on the can. A practical joker could put water in the outlet and it would stay in there until you fire it up. Any suspicious characters in the area? | ||
| Ratbuell |
They'd have to be dedicated...the outlet faces down. Don't park near garden hoses. |
