Smoke on dyno

[busanewb]

I just got my 2015 hayabusa with only 4,000 miles dyno tuned. Nearing recline I noticed some grayish/black smoke coming from the exhaust. Is that normal or am I getting blow by or valve seal leaks? Bike seems fine and I'm not seeing any smoking while on the street.

Running a little rich on top end ? Maybe normal.

you will see things in the dyno room that you may not see in the street . . .

The motor is near new, obviously just a tad rich, or even just blowing some built up carbon out of the mufflers.
Nothing to worry about, just ride it and enjoy it!
