black smoke at start up. :(
Took a 320 mile road trip yesterday. My first long trip ever on a bike. Had a blast.
But, I let a friend sit on my bike and he started it up with out waiting for the little light to go off. I noticed Black smoke come out the pipes. And then i noticed the same thing happening Through out the day. Whenever i would start it up. It would clear up very quickly. Hope its nothing serious.
Oh and another thing i dont know if its been smoking and i just never noticed it.
I just hit the 1000 mile mark and need to bring it in for service .. Im heading out now. To see if its gonna do it this morning.

RE: black smoke at start up. :(
The ECM richens the mixture on startup, just as the manual choke does on carbed bikes. Should clear up shortly after. You may also notice a slight puff of black smoke while you're cruising and suddenly crack the throttle wide open. This is completely normal and nothing to worry about.
