Engine Break-In; Parking - Yamaha TT-R230 Owner's Manual

Engine break-in

There is never a more important period
in the life of your engine than the first
20 hours of riding. For this reason, you
should read the following material
carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
20 hours of operation. The various
parts in the engine wear and polish
themselves to the correct operating
clearances. During this period, pro-
longed full-throttle operation or any
condition that might result in engine
overheating must be avoided. Howev-
er, momentary full-throttle operation
under load (i.e., two to three seconds
maximum) does not harm the engine.
Each full-throttle acceleration should
be followed with a substantial rest pe-
riod for the engine. To allow the engine
to cool down from the temporary build-
up of heat, cruise at a lower engine
speed.
