The presence of a carbon smell from the engine during operation

[alarjan]

Hello friends, I have a problem with a Gold Wing GL1800 - 2007 bike, there is a carbon odor without smoke, while the engine is running in its normal mode, and the engine sound is unstable ,,, what is the solution to this problem ,,,

Sorry ... never heard of a carbon odor.

You may be referring to a nasty exaust smell like rotten eggs. I get that sometimes on my 2005 GL1800. Not sure what it is perhaps the catalytic converter. All I know is, it stinks. Maybe someone can tell me so I can get rid of it.

Smell of rotten eggs is from the exhaust and caused by the catalytic converter.
I haven’t heard of any “fix” for the problem.

Thanks what a bummer. Still no better motorcycle.

Yep, catalytic converter.... Here is a DIY and info blurb:

Have you put excess fuel treatments in lately?
Or maybe somebody's messing with you?
