Instruction Manual for/ Cylinder Kit
For exclusive use with TAKEGAWA Super Head 4VALVE

COItem No.: ０１−０４−０１１９ (125 cc)
０１−０４−０１１８ (138 cc)

・Thank you for purchasing one of TAKEGAWA products.
・This is a piston and a cylinder set for exclusive use with TAKEGAWA Super Head 4VALVE. Please strictly follow the instructions to install and use the kit.
・As this aluminum casting cylinder can be used with our stick thermosensor, you can measure temperature of the cylinder with our optional meter.
・The sleeve of this cylinder is one-piece aluminum construction with the cylinder and is ceramic chrome plated.
It allows this aluminum sleeve to increase more durability and more wear-resistant than cast iron sleeve, and to decrease the piston clearance and friction
loss. The piston is a lightweight design, and molybdenum coating is applied on the piston skirt in order to better break-in.
◎ Please note: Illustrations and photos may vary from the actual hardware.

Please read the following before installation.
！Points to notice about sounds！

After installing this product, in some cases a cooling fin in the cylinder may resonate, making a noise. In this case, as a measure, fix a damper includedin the kit to the cooling fin of the cylinder.

PY◎ We do not take any responsibility for any accident or damage whatsoever arising from the use of the products not in conformity with the instructions inthe manual.
◎ We shall be held free from any kind of warranty whatsoever of products other than this product if any defect takes place on the other products than
this one after the installation and use of this product.
◎ If you make modifications to the products, we shall be held free from any guarantee of the products.
◎ This kit is for exclusive use with TAKEGAWA Super Head 4VALVE.
◎ A cylinder included in this kit may interfere with crankcases depending on individual differences of the stock crankcases. If there is interference, thecrankcase needs some modifications.
◎When you modify the stock crankcase, you need removal or disassembly of engine and crankcase. Be sure to see KAWASAKI’s genuine service manualand work properly. When installing, you need new gaskets. Please purchase them separately.
◎ Please be informed that we shall be held harmless against any claim against us whatsoever arising out of use of the products in racing and the like.
The following show the envisioned possibility of injuries to human bodies or property damage as a result of disregarding the following

Caution cautions.

・This product is designed for exclusive use with off highway or closed road. NEVER use on public roads. Please drive safely and follow the local
traffic law.
・Work only when the engine and the exhaust system are cool to avoid burns.
・Prepare appropriate tools and work properly to avoid the breakage of parts or injuries.
・As some products and frames have sharp edges or protruding portions, work with your hands protected to avoid injuries.
The following show the envisioned possibility of human death or serious injuries to human bodies as a result of disregarding theWarning following cautions.

・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.)
・Always use new piston pin circlips, gaskets, seals and the like. Worn or damaged ones may cause accidents because of breakage of theseparts.
・Before working, place the motorcycle on level ground to stabilize its position for safety to avoid the motorcycle overturning.
・If you find damaged parts when inspecting or performing maintenance of your motorcycle, do not use these parts, and replace them with newones. (The continued use of these damaged parts could lead to accidents.)
・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.)
・Before riding, always check such parts as screws for loose.
If you find loose ones, screw them securely up to the specified torque to avoid parts coming off.
・When you notice something abnormal with your motorcycle while riding, stop riding immediately and park your motorcycle in a safe place to avoid
an accident.
・As gasoline is highly flammable, never place it close to fire. Make sure that nothing flammable is near the gasoline. (It may cause a fire.)・Check or perform maintenance of parts correctly according to the procedures in the instruction manual or a service manual.
(Improper checking or maintenance could lead to accidents.)
・Never use parts other than those specified by us. (Or, the unspecified parts may break, leading to accidents.)
・Tighten parts securely using a torque wrench to the specified torque. (Otherwise, bolts and nuts may break or come off, causing accidents.)
・Since vaporized accumulation of gasoline is quite dangerous, work in a well-ventilated place. (It is at the high risk of explosion.)・Be sure to always use premium unleaded petrol. (Otherwise, troubles such as knocking of an engine may cause accidents.)◎ The product specifications, design and prices are subject to change without prior notice.
◎ We do not accept any complaint filed with us against any technical trouble caused by the combined use of our products with other manufacturers'
products unspecified by us.
◎ Please retain this Instruction Manual for future reference.

〜 Installation Procedures 〜
Caution: Always be sure to tighten parts to the specified torque using a torque wrench.
Notice: The unskilled or those without proper knowledge are requested not to do the installation work.
○ Installation of this kit requires, in some cases, engine removal and crankcase disassembly. Please prepare and refer to a genuine service manual to dothe proper installation work.
○ According to the service manual, demount the engine from the frame and disassemble it.
○ A crankcase may interfere with a cylinder sleeve depending on individual differences of the crankcases. If there is interference, the crankcase needsprocessing.
○ Setting the cylinder in place with a dowel pin, attach it to the crankcase, and check for the interference with the crankcases.
○ In case there is interference, see where the cylinder interferes with the crankcases.
○Referring to the service manual, disassemble the crankcases, and scrape the interfering part with a file or a hand grinder but bit by bit not to over-scrape
the portion.

CO○ In scraping, be careful not to let the cutting chips and shavings into bearings and other parts. After the processing of the crankcases, clean them.
○ After disassembling the crankcases, check every component referring to the service manual.
Caution: Do inspection of every component and replacement of consumables, with utmost care.

・Measure the deflection of the crank shaft.
∴ If larger than 0.08 mm, replace it.

・Check the inside of cylinder for wear and damage.

・Measure the internal diameters of the cylinder bore at

6 positions; at the piston pin angle and at the rightangle to it (X-Y) each at upper, middle and lower partsof the cylinder bore.
Treat the largest value as its internal diameter.
