●
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 the specifications of motorcycle to equip

The cylinder length of this complete engine is longer than that of the stock engine.
It is impossible to install on stock motorcycle chassis. NOTE: Modification of the chassis is required.
For Monkey / Gorilla, modify the chassis if necessary after checking whether the installation is possible

About upper limit of revolution:
◇
Max rpm may vary by the camshaft and engine specification, always use taco meter to avoid over-rev the
engine rpm.

Exhaust camshaft : 20
Maximum rpm : 12000 rpm
138cc : Intake camshaft : 25
Exhaust camshaft : 25

◇
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.
Rearsets:
◇
To use rearsets, you may need to modify the drive sprocket cover.
