Re: Break-In Procedure
Vary the throttle amount and engine speed.
Don't do a lot of closed throttle downhill runs. (never a good idea with a two stroke).
Check your plug after the first 15 minutes if all else is O.K., sooner if it's not. (to make sure your mixture is close).
Don't go far from home for the first hour of operation, though you'll likely need to tweak the installation, not the engine itself beyond maybe a carb adjustment.
