Precautions of Use
〜
●
An Engine NO. (Serial No.) is stamped on this engine as identification.
Please specify your Engine NO. when ordering repair part or contacting us.
About fuel
:
◇
Whenever regular gasoline is remaining in the fuel tank, always replace it with high-octane gasoline.
About oil cooler:
◇
The installation of this product increases the heat release value of the engine, set off by the increase in
power. We recommend you, therefore, to install an oil cooler kit, for a long-time high-load running, which
keeps oil at appropriate temperatures and prevents such troubles as oil film shortage at high temperatures.
●
In case you use the breather cap, be sure to use an oil catch tank at the same time.
Due to large displacement engine, blow- by gas volume may increase. Larger capacity catch can are highly
recommended. (approx 500 cc)
About upper limit of revolution:
◇
The upper limit of revolutions varies depending on the installed camshaft and other factors. Please install a
revolution counter to make sure that you drive the engine at revolutions below the upper limit, referring to the
Camshaft Comparison Data List.
◇
Take note that engine racing and sudden acceleration, particularly in the 1st or 2nd gear, tend to exceed the
upper limit of revolutions.
Over revolutions will result in nonsmooth revolutions of the engine, not only adversely affecting the engine
life, but also possibly breaking the engine in the worst case.
