Howdy yall, I'm new to this site, and buells in general. Also I know as much about engines as a tree stump. I'm curious what happens to the buell muffler when its completely submerged in water - moving water at that. Let's suppose in a worst case scenario where the exhaust pipes have been submerged under water in a stream, and the current is flowing directly into the open exhaust. I was under the impression that after the exhaust cleared the water, any water inside would just get blown out or evaporate pretty quickly. My friend seems to think it would mess up the engine but for the life of me I can't imagine how, unless you were waist high in water and it flowed into the air intakes. any info much appreciated, Brane | ||

The back pressure would be high, especially if the engine was not running when the exhaust filled up. That being said, the headers are strong and tight, as is the exhaust, so it's not like the piston or crank will be seeing any sorts of super dangerous pressure. The real damage would probably be to all the exposed bearings, and getting water in the transmission. The exhaust would probably be fine. | ||

I dont know much about engines, but I thought the only place for water to get in would be through the air intake? A foot or so of water should be fine right? as long as the water can not force its way all the way back up the exhaust pipe to the (running) engine, which is highly unlikely?

To cross water of a known safe depth (walk it first if in doubt) the best bet is to get into your lowest gear and enter with the RPM up around 2,000-3,000 or so. Then try to keep the RPM up and steady with the throttle and don't use the clutch. On most bikes the limitations will be when the plug(s) gets wet and shorts out or when the water gets to the inlet tract. Then there is the WFO banzai technique. That's usually only good for narrower crossings. Jack | ||

Water getting into the exhaust would be blown out and what was left would evaporate quickly - no worries. Some water condenses inside the exhaust system just about everytime you start the bike, btw. Tell your friend to go dunk his head. | ||

I would bet you will get water into the transmission through the 5th gear drive assembly, shifter seal, and clutch cable. Not a ton, but some. It should boil out with a good hot ride, but if you do it much you might want to make your transmission fluid changes more frequent. As will be your wheel bearing changes. | ||

alright, there's a story behind this question -- I'll bet it's a duesey! | ||
| Branebanger |
nope, no story. Just trying to do a bit of homework before i smack down 12 grand cash. I have a gsxr1000 and a XR650R so it's been REALLY tough finding a bike that I felt could do double duty. Nothing seems to live up to my expectations. I've been going back and forth between a GS and a KTM for the past 1+ year, but still have not made the decision to buy. I was really excited to see the Ulysses, but 2 things were bothering me, the exhaust and the front wheel durability. I'm not going to be going through any water higher than about a foot or so, it seems that is not a big deal as long as we are talking about minutes not hours of water. But I'm still freaked by the front wheel - the spokes look like oragami. its probably my imagination but the front wheel looks the same as the street version?!?!? Please tell me there is another wheel option than that? | ||
| Branebanger |
btw - where the hell do you buy the dam thing? I've looked all over the tri-state area and nobody has one. tx for the feedback on the muffler stuff - its as I thought, not a big deal for what i'll be doing. | ||

To stand up to fire road use, the Uly front wheel is built a bit stronger than the street wheels, adding about 1 lb of weight. Knowing which tri-state area you're looking at will make it easier to help you find a stocking dealer  Henrik | ||
| Reepicheep |
Henrik... if you recommend one *your* tri state area, I think he will probably have the answer he will need. Don't tell anyone I told you.  | ||
| Henrik |
Well, in that case - Liberty is a sponsor and their banner is right above as I type this  Henrik (there are no other tri-state areas in the US?? - who knew) | ||
| Reepicheep |
Well, there is only one tri state area for his IP address... if ya know what I mean | ||
| Branebanger |
yup - that's the right tri-state area. could have sworn i called them but i'll try again. tx btw - you should go get a commission or something I just put a deposit down. (Message edited by branebanger on August 03, 2005) | ||

Reep; ahh, you're a sneaky one - but then I knew that already Brane; I'll keep that in mind  Liberty have done a great job of jumping solidly on the Buell band-wagon as of late. I'm sure you're in good hands there. Henrik | ||

My headers are really hot. Will a heat shield help? | ||
| Buellistic |
The rear ex. pipe out of the rear cylinder is supposed to have a heat sheld on it !!! (Message edited by buellistic on February 11, 2006) | ||

Buellistic: "Supposed to have a heat shield"? Are you saying the new XB Lightnings have a rear cylinder heat shield or they should have been designed with one? DAve | ||
| Chefa |
Have an 05 xb12s and it definitely does not have a heat shield, the pipes are unnaturally hot. | ||
| Buellistic |
Dave: MY "MISTAKE", "i" should have checked PORFILE to to see what Model was in question ??? TUBE FRAMES came with a heat shield on rear header on bend out of the cyclinder ... "YES", it should have been designed with some kind of heat deflector/heat shield !!! In BUELLing LaFayette | ||
| Dave |
Chefa: Someone reported their exhaust valve was stuck and caused the pipe to get extremely (glowing) hot. Maybe worth a check. Then again, my brother and I both have matching scars from the hot exhaust header of a '68 Triumph T100-C DAve | ||
| Buellistic |
IMO that is a AIR LEAK ??? | ||
| Chefa |
Hey Dave, what does it mean to have an exhaust valve stuck? My pipes don't glow but the heat makes my right leg uncomfortably hot. I purchased a metal heat shield but haven't tried it out yet. I think it might be more of a "look" thing than functional, but we'll see. So far no scars...yet. |
