black smoke...

[melloGS]

Out riding today with some buddies and one of them told me that when i downshift, black smoke comes from my exhaust...burning oil....is this a serious problem, i've heard quite a few of you say the GS is known for burning oil...
?

I believe blue smoke is oil... You might be running rich...

When I downshift, massive tongues of dazzling flame and scalding fireballs are spewed forth by my exhaust can which ignite and consume any and all vehichles behind me.

The only smoke anyone sees is that rising from the smoldering ashes of the burnt out, charred husks that are all that remain.

A fire engine was once enveloped by this furious malestrom.  How is that for irony?

yeah... it sounds like it's running rich...

Have you done any modifications to the air filter/carbs/exhaust? If not, you should check your air filter as it may be clogged.

Ealier this year my cbr had ignition problems and when I tried to start it flames would come out of the exhaust

My sportster has the short drag pipes. If I pull the choke for a few seconds and push it back in then rev the hell out of it... I get flames...
