Breaking-in
From scoot.net
Breaking-in, unlike breaking-up, is not hard to do...if you're patient.
Certain parts of a scooter must be gently eased into use vice slapping them on and hauling ass.
[edit]
Top End (Cylinder + Piston)
To break-in a top end properly, obey the following principles:
- Do not rev the bike out. Take it slow.
- Vary the throttle between 1/3 and 2/3 in a smooth manner. Do not maintain consistent revs for more than 1/4 mile or so.
- Use a 4% mixture of "dinosaur oil" during this process.
How long should you do it?
For an iron-lined cylinder and piston, estimates vary from 300 - 900 miles. For a nicasil-lined cylinder and piston, such as the ts1, imola, and mugello kits, 100 miles is a safe break-in range.

Piston Rings
When putting new piston rings within an already broken-in top-end, you need to allow the rings to 'mate' with the cylinder wall. Following the above principles for 100 miles is sufficient to do this.
