Re: Smoke and tailpipe soot after oil change
The O2 system is open loop initially and runs full rich. Thus the black soot and if enough moisture is collected in the exhaust it will blow out that soot with water droplets and make a nice smudge on the floor. Perfectly normal for this bike. You can remove it with Windex and a tooth brush but it will always come right back on the next cold start.
