Engine Break-In; Parking - Yamaha TT-R230A Owner's Manual

OPERATION AND IMPORTANT RIDING POINTS

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 care-
fully.
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-
6
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 peri-
od for the engine. To allow the engine
to cool down from the temporary build-
up of heat, cruise at a lower engine
speed.

Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.
Do not park on a slope or on soft
ground, otherwise the vehicle

risk of a fuel leak and fire.

flammable materials
might catch fire.
