Complications after fixing overheated stock mufflers

Anyone experienced this before or know the cause for stock mufflers overheating? It's to the point that the plastic mounters for the license plate holder is melting. The bike has only done 3500 km and was running fine the day before. Started it up todayand the engine just would reach normal working temperature. Stayed at around 70 to 80 degrees and the torque was only 60%. Stalling easily. While overheating at the muffler; the inside glowed white hot. The outside of the aluminium stock cans are now tarnished slight brown. Please feel free share your thoughts.

Sounds to this guy like one of two things... clogged exhaust, or extreme Lean condition. Call the dealer!

Dude,

This is serious.. My buddy's bike did the same thing.. DON"T RIDE IT AND TAKE IT TO THE DEALER.. YOU STILL HAVE THE WARRANTY RIGHT???

Good thing is he brought a full Termi system and it was done.. But the dealer did a full system check, got an oil change some other stuff... As my dealer will tell you these bike MUST BE ABLE TO BREATH.. If you are riding with the throttle open with stock can the bike is not breathing and MAY be from that but I'm not for sure.. Also are you riding in traffic??? Are you reving the enginge at a stop light to hear her scream??? Cause that is another NO-NO the 1098 has a small radiator also so it needs lot of air flow.. I know that I'm contradiction my self but these bikes are very picky.. You may have to cough up 2,500 for a system... But I will say this it should not be doing this.. SO WHATEVER YOU DO ON TUESDAY TAKE HER IN AND LET THEM TAKE A LOOK AT IT. Something is going on that could be even more serious than I or any one else on this forum may know..

Your life is not worth it if she locks up on you...

I agree, I would not ride it. If the bike is running really lean you don't want to cause serious damage.

Take it to the dealer and let them deal with it and whatever is damaged is at this point, have it replaced.

Was only getting out of the driveway after warming up. No traffic nor revving at stand still. The sound from the engine did sound weak though. Not as deep a thump as normal. But engine light did not come on.

 

[Visitor Q]

Even so, you don't want to have the plugs melt or some $hit like that, you could cause MAJOR DAMAGE!

The only pictures I have ever seen of exhaust getting to the point of the hot you are describing was a full Termi setup with the baffles in.

Would it be possible to take a few pictures?

Jason

 

[nivo]

yep, in a few hours when I get back home. And I'm definitely not riding until the dealer worked oj it.

Better safe than sorry.

If the temps in the cans get as hot as quickly as you say, let the dealer know whats going on and suggest that even if the bike is not technically immoblised, it may be cheaper for Ducati to pick up the bike under the 2 year road side assistance agreement than to reapir more serious dammage.

Just a thought, might save you a cab ride home.

Cheers

I think I remember this he was running termi slip on and burnt the hell out of them as we can see...

Too rich. It will heat up the cats.

Rich? hmm... maybe yeah. At that point, the un-burnt gas fills the silencers up? Not 100% on that, i'm unfamiliar

Nah… I’m pretty sure it was a full system at the track with the baffles in it.

Jason

 

[gillistheman]

seems to me like the baffles are nothing but trouble...

Well if those pictures are any indication, I’d say so.

The system I have never head them ran in it and never will.

Engine diagnostics from the dealer shows a faulty exhaust exit valve. Testing shows it not responding to any throttle action. It is supposed to open an aperture according to the throttle angle; so as to allow higher emmission at higher revs. A faulty valve would mean trapped unburnt gasoline fumes along the exhaust system resulting in additional burning within the pipes and hence the overheating mufflers to the point that the plastics around the area melted.

Well that sounds bad...

pictures taken at the dealer's garage;
1. tarnished mufflers.

2. license plate holder and cans securing rings melted by the excess heat.

3. splurts of gasoline on the pipes around the fitment areas shows excess of unburnt gasoline built-up in the pipes.
