New bike/fazer owner, proper way to go about the initial service?

[kgjersda]

So I hooked up CarbTune and calibrated as best I could. It's running much smoother now.


However, I saw that the first tube was much more volatile than the three others. The bike has some dips and surges when idling around 1150-1250, not a lot though.
Is this normal behavior? Should it be dead stable when idling?


To do:
- Change spark plugs
- Check/change air filter
