Engine Break-In - Yamaha TW200 Owner's Manual

OPERATION AND IMPORTANT RIDING POINTS

Engine break-in

There is never a more important peri-
1
od in the life of your engine than the
period between 0 and 1,000 km
(600 mi). For this reason, you should
2
read the following material carefully.
Since the engine is brand new, do
3
not put an excessive load on it for the
first 1,000 km (600 mi). The various
4
parts in the engine wear and polish
themselves to the correct operating
5
clearances. During this period, pro-
longed full-throttle operation or any
6
condition that might result in engine
overheating must be avoided.
