I fired off the 954 yesterday, it had been sitting for about 4 days. My father wanted to here my new bolt on so I started it and revved to to 4 or 5k with it cold and it was puffing black smoke. When it warmed it was puffing white smoke when I revved it to around 6k. The bike only has 2k miles on it and is still under warranty. Should I have it checked or is it normal? I didnt know if it ran rich when first started because of the fi. It is stock except for the bolton. I have only had it about a month.
