About fuel:
Whenever regular gasoline is remaining in the fuel tank, always replace it
with high-octane gasoline.
②
With this kit installation, a centrifugal filter will be lost. So, please install a
dry-type clutch with an external oil filter or a special clutch.
③
Change of a sprocket
◇
The installation of this kit will increase the power of your vehicle. So the
continued use of a stock sprocket will result in severe wears of parts
because of too low gear, not only adversely affecting the engine life, but
also breaking the engine in the worst case. Therefore, please change the
sprockets with the high-geared one.
※
This kit is only compatible with those engine parts recommended by us.
So, please replace the engine parts not recommended by us with those of
our recommendations.
●
Our recommended engine parts:
Oil cooler:
◇
The installation of this kit increases the heat release value of the engine,
set off by the increase in power. For a longtime and high load running, we
recommend you to install an oil cooler kit which keeps oil at appropriate
temperatures and prevents such troubles as oil film shortage at high
temperatures.

A serial number is stamped on the cylinder head. You may be requested
to inform us of the number when ordering repair parts.

If you have bought a head kit alone, this head kit
alone does not work. Please purchase a special
bore-up kit with reference to the attached sheets.
●
For those who have purchased a cylinder head alone, selection kits are
available to meet your combination demand depending on the
specifications, etc. Please study the required contents of the kit, referring
to the attached “Reference data on bore & stroke-up kit”.
For more details and enquiries, please contact your local motorcycle dealer.

Upper limit of revolution
◇
The upper limit of the engine revolution is 12,250 rpm. Please install a
tachometer, and drive at revolutions below the upper limit.
◇
Take note that idling and sudden acceleration in the 1st and 2nd gears
particularly tend to exceed the upper limit of revultions. Over revolutions
will result in nonsmooth revolutions of the engine, not only adversely
affecting the engine life, but also breaking the engine in the worst case.

Recommended Parts
・
Those who are technically unskilled or inexperienced are required not to do the work.
(Improper installation because of insufficient skill and knowledge could lead to parts breakage and subsequently to accidents.)
・
Before doing work, make sure your bike is secure on level ground for safety's sake.
(Otherwise, your motorcycle could overturn and injure you while you are working.)
・
Always start the engine in a well-ventilated place, and do not turn the engine on in an airtight place.
(Otherwise, you will suffer from carbon monoxide poisoning.)
・
As gasoline is highly flammable, never place it close to fire. Make sure that nothing flammable is near the gasoline. (Otherwise,it may cause a fire.)
・
Always use a torque wrench to screw bolts and nuts tight and securely to the specified torque.
(Otherwise, these parts may get damaged or fall off, resulting in accidents.)
・
Never use any other parts than those specified by us. (The use of the unspecified parts may lead to parts breakage and consequent accidents)
・
If you find damaged parts when checking and performing maintenance of your motorcycle, do not use these parts any longer, and replace them
with new ones. (The continued use of these damaged parts as they are could lead to an accident.)
・
When you notice something abnormal with your motorcycle while riding, stop riding immediately and park your motorcyle in a safe place.
(Otherwise, the abnormality could lead to accidents.)
・
Before riding, always check every section for slack in parts like screws. If you find slack ones, screw them securely up to the specified torque.
(Or improper torque may cause parts to come off, leading to accidents.)
・
Check or carry out maintenance of your motorcycle correctly according to the procedures in the instruction manual or service manual.
(Improper checking or maintenance could lead to accidents.)
・
Be sure to always use premium unleaded petrol. (Otherwise, troubles such as knocking of an engine may cause accidents.)
The following show the envisioned possibility of human death or serious injuries to human bodies as a result of disregarding the
following cautions.
WARNING
◇
If you have purchased a Cylinder Head kit alone, a special camshaft is
needed separately. And if you have purchased a full kit, the cam shaft is
included in the kit.
◇
Please definitely use this cylinder head together with a special cam shaft.
Never install a stock cam shaft.
◇
For use with this Super Head, a titanium valve spring retainer is available
separately as an extra-cost option. We have succeeded in making the
retainer lighter than a steel retainer by about 30 percent. Besides, we
have treated the coating to the surface which has surface hardness of
more than HV2000. Thus, the level of wear resistance has been improved
compared with that of the tin coating. However, when it comes to
durability, this retainer lags behind the steel retainer. So check and perform
maintenance periodically of parts for damage and wear. Always replace
damaged or worn ones with new ones. However, we would recommend
those who attach importance to durability to use the steel valve spring
retainer as it is.
