Exhaust smoke.

[stefman722]

Hey guys,

I was riding with my buddy, and he tells me that when i go full open throttle on my 2004 gsf, that smoke comes out of the exhaust. Now, usually that means i am burning oil. So i parked the bike and reved it, and found that it only smokes at 9500 rpms. It stinks of oil too. So my question to you is why is it doing this? it has never done it before. This is the 1st time ever. Let me know the cause ppl.

Thanks

Stefan.

9500 and above, or just 9500 exactly?

[stefman722]

its more like 9000 and above. Its only does it in the high end RPMs. If its something bad, i need to know as my warranty runs out in 2 weeks  

Thanks guys.

Black smoke or white smoke??
(no this is not a joke about the pope..)

Black smoke = gasoline (too rich)
White smoke = oil

[stefman722]

Its actually a mixture of both. Alot more white though. Would it be some sort of engine damage causing this?

The best advise I can give you is this..
Run a compression check on both cylinders.
I dont know what the compression is supposed to be, but if one cylinder is obviously lower then the other, then you may just have your problem..

The other thing I would say is to have the carbs sync'd..

BTW.. Mine is probably not a good example because it has been monkeyed around with so much, but mine puts out a puff of smoke when you throttle blip it too...

well... you still have warranty... get it in there... and check everything else out on it too...

It must have been oil. My buddy told me to try just changing the oil. So i went and bought some nice motul oil from the dealer. I think my oil was too old in my bike, and was burning too much. Anyways, i completed my 1st oil change by myself and i would for sure do it again. Why pay the dealer, waste of money.

Yea my 48K bike would do it ... with a straight out pipe you'd get liquid oil as well as smoke (burnt oil) at revs ... now hot was better than cold and as it got older the rpm it did it at got lower and lower ...
Cool.

What did you do to fix it, just a simple oil change?
