1. Treat the machine gently for the first few miles to make sure oil has circulated throughout the engine and any new parts installed have started to seat.
2. Even greater care is necessary if new pistons/rings have been fitted or the cylinders rebored, and the bike will have to be run in as when new. This means greater use of the transmission and a restraining hand on the throttle until at least 600 miles (1000 km) have been covered. There's no point in keeping to any set speed limit - the main idea is to keep from labouring the engine and to gradually increase performance up to the 600 mile (1000 km) mark. Experience is the best guide, since it's easy to tell when an engine is running freely.
3. If a lubrication failure is suspected, stop the engine immediately and try to find the cause. If an engine is run without oil, even for a short period of time, severe damage will occur.
