My '07 Road King has been missing/hesitating before the bike warms up. When it get to operating temp it seems to go away. It just had it's 5000 mile service. Any idea's??

Carbon build up maybe?
Try a half of a bottle of this, and see if that helps.
I recently did and it helped.
All I have ever run is premium gas 91 octane too, but I had some spark knock as well.

Seafoam seems to help.

I have never, ever, added any type of oil or fuel crap. If the bike isn't running properly, seafoam, techron or wd40 isn't going to fix it.

Were the plugs changed? Are they and the wires installed properly? Is the heat range correct?
