Before fitting the kit, please be sure to check the contents. Should you have any questions about the kit, please kindly contact your local motorcycle dealer.

Please read the following before starting the installation

We do not take any responsibility for any accident or damage whatsoever arising from the use of the kit not in conformity with the instructions in the manual.

Please note that this kit is designed for exclusive use in the above-mentioned applicable models and frame numbers only and that it cannot be mounted on

other models. 

   

Installation of this kit requires engine removal and crank case disassembly. We strongly recommend you to work strictly following a HONDA genuine service

manual for your vehicle with enough care. Besides, this instruction manual, as well as the HONDA service manual, is prepared for persons who have 

  

acquired basic skill and knowledge in tuning. We, therefore, recommend those who are technically inexperienced or without right tools to ask a technically-

trustworthy specialist shop to do the work.

We shall be held free from any kind of warranty whatsoever of products other than this product if the glitch takes place on the other products than this one

after the installation and use of this product.

If you make modifications to the products of the kit, we shall be held free from any guarantee of the products.

You are kindly requested not to contact us about the combination of our products with other manufacturers'.

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

Some of bolts, nuts, dowel pins and packings will be reused. However, be sure to replace worn-down or severely-damaged ones with new ones.

Never use liquid packings, or it may block oil passages; it may break the engine in the worst case.

Be sure to always use premium unleaded petrol. And make sure to check what kind of gasoline is remaining in the fuel tank. Whenever regular gasoline 

remains in the fuel tank, always replace it with high-octane gasoline.

Determine the heat value of a spark plug depending on how much it is burnt. In vehicles originally with a resistor plug, always use a resistor plug.

Never use this kit on the point-ignition system motorcycle.

Please be informed that what we can safely say is that the ignition system is compatible only with ours and stock ignition systems, because no data is 

available with us on the compatibility with other ignition systems. Therefore, please never use other ignition systems, which may cause technical troubles.

Install an oil cooler when necessary.

Engine oil must be API SF or higher class, such as SAE 10W-40 / 15W-50, which are our recommendations.

Change the sprocket with the one which meets the output and specifications.

This kit cannot perform on its own. Please see "Engine Parts Recommended by TAKEGAWA" on page 2.

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.

This kit is designed for exclusive use in the closed racing. So, take note that it is prohibited to drive your motorcycle on a public road after the installation of

this kit. Drive your motorcycle at a legal speed, abiding by the laws.

If you have purchased a cylinder head kit only, the camshaft is an optional extra. So, please purchase a special one.

Features

Please be informed that, mainly because of improvement in performance, design changes, and cost increase, the product specifications and prices

・・

are subject to change without prior notice.

This manual should be retained for future reference.

This is a totally new cylinder head of TAKEGAWA’s original design with larger top diameters of the intake and exhaust valves and with a shorter stem 

diameter. In addition, we have improved the power output efficiency through the special development of valve angle of nip, port shape, and the combustion

chamber shape.

Please note that idling, sudden acceleration, and sudden engine braking will put a heavy load on the engine. It may result in crank shaft damage and
engine breakage in the worst case.

Quick starting and sudden acceleration

 Please note that, in some cases, the illustrations and photos may vary from the actual hardware.

The Ape and XR50 Motard must be bore- and stroke-upped ones.
