Big problem with my right exhaust pipe

[Vampyre]

Ok i have the falco fighter exhaust and heres the problem

When i was washing the bike today i noticed a 3 inch by 3 inch area on my right pipe the bottom half that is burned and a small area where the pipe starts is burned as well.

The carbon fiber is all brown and black in the middle and crustey. But not to the point of flaking off.

I warmed the bike up after i finished washing it. and noticed that the right pipe is 2 times warmer then the left pipe and that the area where its burned is about 4 times hotter. in other words. I can keep my bare hand on the left pipe all day long and it just slightley warm. the right pipe i can keep my hand there for about 4-5 seconds. and where the spot is i can barley touch it for less the a second.

Ive been noticing a that the bike feals different after i had the 10k service done. i cant pin point it but it feals different in a bad way i dunno. and both pipes have always been around the same temp fealing wise before. and i have never had a single problem with the bike in the past.

Anyone know WTF is going on?

the bike has just over 11k miles on it and is a 2002

Here are the pics












thanks

My best guess not knowing exactly what the baffles or packing look like is that possibly there is a problem with the internals that is deflecting exhaust gases to that point in the muffler. If there is now some obstruction in the baffle/packing it can be impeding the exhaust flow causing back pressure, causing a change in running, IMHO........It would seem that it will continue to get worse resulting in burning thru / out the muffler or pipe. The obstruction thing really seems most likely......

I'm no expert, but it sounds like one cylinder may be running way too lean, to generate that much heat into the exhaust, to have it start burning away the CF of an exhaust.

Why this would be? I really have no idea, and I may just be talking shite! (Likely!)

Take your plugs out and have a look at them, as that may give you a clue!

What symptoms do you get whilst riding? (You said, it feels different. How so?)

Not much help.

[Vampyre]

While riding it seems to do something when taking off from idle and just on off throttle like a slight loss of power and it just does not seem as quick as before.

Well looks like ill be calling af1 in the morning as thats who did the 10k service. Guess if its there fault thell have to do something about my exhaust as well.

O and want to hear some really great news. my bike is the only transportation i will for 16 to 18 weeks while my new STI is being built in japan. I finally found a buyer for my 2001 integra type R after 6 months of trying and the delear had the one i wanted but sold it a day before i got there.

I have my 2000 rsvR in the garage but its not insured and im thinking of selling it latley. So thats out. well hopefully this wont be a major problem.

if i had pics i would take them but i have not digital camera.

Check the muffler first. Keep it simple. Heck even put on the stock pipes for a test run.
I disagree about it being lean. I would think too rich would leave fuel in the exhaust and burning in the pipe. Lean does make it hotter but usually near the headers not in the muffler.

[Vampyre]

well they said that its caus the pipes have not been re packed ever. and that it should be done every 5000 miles. i have never heard this about any exhaust.

[Firebolter]

I had a similar problem on my old beemer. Loss of power, wouldn't idle right. Turned out that the exhaust valve was almost closed and not opening enough. My header pipe got red hot, like glowing. If they did a valve adjust, I'd have them look at that. If the bike is so lean it was generating that kind of heat, your rings could be near toast, don't think that is the problem...Seems like it might be valve related.

Something definitely ain't right and i wouldn't ride it till I got it checked out...

[Vampyre]

yeay they did a valve adjust and flushed the suspension fluid on the front forks. Im wondering why they did not suggest this so called re packing when i was there.

running lean might be it as i have noticed a 2-3 mpg increase since the service i though it was caus of the valve adjust.

[Firebolter]

It takes alot of heat to cause the symptoms you are describing. I'm not saying they did anything wrong, but an out of spec valve can have a similar outcome......Since you paid for the service, I'd have it re-checked if I could.

[CarlosT]

I'd take the mufflers off and stick some kinda CO probe and check each cylinder to see if one is burning too lean.

The other problem could be some kinda pipe obstruction but that wouldn't improve your mileage...I wouldn't think.

[Vampyre]

If i take it in it seems to me thell just re pack the exhaust. im calling mototek to get there opinion. but jay never seems to want to pick up the phone over there.

Ill try to use a phone camera to post the pics if it has a resonable res. no one i know has a digi camera

and all i know is the my exhaust is now ruined.

[CarlosT]

Is the pipe ruined or the can? It would seem to me that the packing would have to be severely deteriorated to cause a pipe to be destroyed by heat.

[Vampyre]

the can the carbon sleve. all i know is that you cant touch the right can after a good ride while the left you could lick it if you wanted to.

like i said theres the big spot 3.4 of the way back then a little spot where the can starts.

the exhaust sounds normal as it always has though. I just ride the thing i dont really know how to check for any of the things you guys said. now if it was a car i probley could.

I can pre wire an entire house for a hometheater and setup and calie the a/v though ^^

o and mototek is gone till thrusday figures.

[CarlosT]

Sounds like the packing is outright missing...a Monday morning batch after a weekend of heavy vino consumption at Varese

There is an article on Motorcyclist Magazine on line in the how to section on re-packing mufflers.
I've never had to do it, I've got Staintunes on my Falco. Love em, sound good, look good, and no maintenence.
