Just give it a gentle start for the first 3 tank fillings. Most important is a varied throttle in order to give a good run in, with good cooling through fuel. Avoid at all times WOT at no load. Run it with the recommended 2% alkylat, eg Aspen fuel mix.

Forget about all the nonsense you've heard and read about calibrations and resets, that's mostly uninitiated hear says without substance.

Rather run the saw in real work situations, while it go through the training cycle, continuously adjusting to fuel choice, ambient temp, altitude etc.

At the end of the 3 tank run in period, give it some bigger bite to work with, to really adjust for it's max performance.

The saying, that the harder you run the saw, the better it performs, really is true. But give it a throttle variation, as all two strokes depends on fuel supply for cooling.

You might notice after using the saw for a while and your senses are sharp, that after lighter work as cleaning and light delimbing, the saw response has adopted to that low demand work. That's not the intended prime scenarios for this race machine, so you might let the saw go back to a higher work load, in order to get optimal performance again. Over time, using your musical ear, you'll easily learn to monitor the saw tuning state.

Check the tension frequently of a new chain, learn when to use the choke and high idle, monitor your start learning problems, though seldom happens, with a spark plug check up. Keep the chain sharp, and choose a 15" bar for best balance.
