Features●Use of an automatic decompression camshaft:◇ To have two overhead camshaft and two intake valve and two exhaust valve, it is possible enlarge theoverall valve size. Also incorporated with direct lifter makes compact and lightweight as much as possible.
Camshaft moves with semi-gear train and adjustable camsproket, which makes possible to adjust valve
timing.

●Use of Plated Cylinder:◇ We have designed this automatic decompression mechanism so the temporary decompression by thismechanism on the camshaft makes it easy to press down on the kickstarter arm to the end, even if the engine
is highly compressed.

◇This cylinder is aluminum one-piece construction and the ceramic chrome plated inner wall allows the
additional wear-resistance and the reduced friction loss. It also features both high gas tightness anddurability.

● Use of Oil Jet:

PY

◇ We have installed the oil jet which works to jet-spray the oil to the rear side of the piston from crankcase oilline in order to cool the piston.

● Use of Wet Multiple-Disk Clutch:◇We have installed a multiple-disk clutch with 5 disks onto the transmission main shaft so it can respond toeven high output powers.
This arrangement serves to improve durability of the crankshaft and throttle response. In addition, we haveinstalled a highly-reliable cartridge oil filter on the clutch cover. The clutch cover is so structured that a newline is prepared for taking out an oil cooler from the clutch cover and a thermostat can be installed as an
option.

● Use of close ratio transmission:◇ The close ratio transmission is designed to enable smooth shift up and down and cornering, and, moreover,effective transmission of engine power.

●Use of Lightweight Outer Rotor ACG◇SS-outer rotor is equipped as standard .Rotor body is a compact design and it weighs 536g. The best ignition
timing is set up exclusively for this complete engine and the quick response has been achieved.

COHow to Set the Carburetor

・When the carburetor does not match the engine and the engine fails, the engine failures are caused by either too dense or too lean air-fuel mixture.
・The engine failure symptoms for the engine are as follows:

When the air-fuel mixture is too dense:

When the air-fuel mixture is too lean:

・The explosion sound with a dull thud continues intermittently.

・The engine overheats somewhat.

・The engine malfunctions further if you use the choke.
・The engine malfunctions when you warm it up.
・The engine works well if the cleaner is detached.
・The motorcycle belches dense (or, black) exhaust gas.
・The plug smolders, getting blackened.

・The engine starts working well If you use the choke,.
・The engine does not accelerate well. (No smooth acceleration)
・Revolutions change, generating weak power.
・The plug burns white.

PY※ Set the carburetor only after warming up the engine, and then test-drive. And use a plug with the right heat value.
※ Do the setting in the following manner, studying at what throttle opening position the engine starts failing.

○Jet needle (Throttle position at 1/4 - 3/4)

○ Air screw

Whether or not the engine revolution is in proportion to the throttle operation
・When the acceleration is not smooth or even, make the air-fuel mixture dense.
・Make the air-fuel mixture lean when the engine revolution goes up heavily and belches black gas.
The mixture ratio at this throttle position can be adjusted by the location of E-ring in the grooves.
The air-fuel mixture becomes dense as the location of the E-ring moves down from the 1st to the 5th groove.

The air screw adjusts the air mass flow at the time of engine’s revolving at slow speed. (At idling)
・Give the air screw a right turn → The air-fuel mixture gets dense.
・Give the air screw a left turn → The air-fuel mixture gets lean.
Loosen the tightened air screw back to the 1.5-turn position. And then from this position, give to the airscrew
a right or left turn of 1/4 to 1/2 till the engine revolves at the highest speed.
Loosen the idle stop screw till you get the steady idling revolutions. And once again adjust the position of the
airscrew to get the highest revolutions.

●On how the barometric pressure, temperatures and humidity affect the setting:○Main jet (The throttle position at 3/4 - 4/4)

・At highlands or at high altitudes, the barometric pressure and air density go down and the air gets into the
carburetor in less amounts.
This makes the air-fuel mixture dense which was adjusted at low altitudes.
・Under the weather conditions with very low temperatures, the air density increases, which makes the
air-fuel mixture lean.
・Under the rainy and humid weather conditions, the air density decreases, which makes the air-fuel mixture

The air-fuel mixture ratio at this throttle position can be adjusted by changing the number of the main jet.
The larger the main jet numbers, the denser the mixture ratio becomes.
In view of the engine and muffler specifications, select the most appropriate main jet to get the highest
revolutions.

○Pilot jet (First of all, please adjust the air screw.)

dense.

・In case you have given more than three turns to the air screw to tighten it, use a pilot jet with a small number.
・If you have tighten the air screw (clockwise) to the full, use a pilot jet with a larger number.
Check whether you have made a right choice of the pilot jet by seeing if the engine starts up revolving smoothly from the idling to running at slow speed.
・When the engine revolves up unevenly, the pilot jet number is too small. (At idle)
・ When the motorcycle belches black exhaust gas and produces heavy exhaust sound, the pilot jet number
is too big. (At idle)
・After replacing the pilot jet, you need to readjust the airscrew.

CO☆ Change the valve timing.

○ Valve Timing Adjustment:○ Positions of Cam Gear and Dowel Pin:

○ Set the piston at the top dead center (TDC)position.
○ Attach the timing protractor to the crankshaft, and set the protractor dial at “0” and tighten the nut.
Recheck that the piston is at TDC.
(In case it is not right on the TDC, adjust it with a pointer.)∴Timing protractor : Item No. 00-01-0062◎ Change of the position of a cam gear dowel pin will make it possible to change the valve timing.
○ The lobecenter at each dowel pin position is as per the illustration below. However, as this is just for yourreference only, figure out the exact angle with a timing protracter and dial gauge.

EX○ Set a magnet base stand so the dial gauge is vertical to the cylinder head valve lifter surface.

At this point, pressing the dial gauge. And set the dial at “0”.
(Use a special rod so the dial gauge rod does not interfere with the camshaft)○ Rotate the crank shaft counter clock wise viewed at the left side of the engine, and read the lobecenter.

PY☆ Valve opening,
Turn the crankshaft counterclockwise, when 1mm lift the valve, which called “Opening valve”. Keep turn the
crankshaft counterclockwise when 1mm lift the valve which called “Closing valve”.
☆Cam lobe,
Turn the crankshaft counterclockwise, when maximum lift the valve, read the timing protractor.

○ Shifting of the pin position from the originally pre-set position will degrade the performance.
If you would change the pin position, please always try to do so without changing the cam top position as
per the above illustrations.
○ Those who are not familiar with the valve timing are required not to shift the position.
Caution:○ When you adjust the valve timing with the head installed to the motorycle, valve lifters sometimes fall off
at the time you remove the camshaft at the exhaust side. If the valve lifters have fallen off, detach the head
cover, and reinstall back the shims and valve lifters at the original positions.

our Standard Type and the corrugated louver fins are incorporated. This cooler body has an oil cooler plate and guard as standard equipments. In addition, the bracket
mounting is integrated with the oil cooler plate so that you can use the oil outlet upside down as well.

PY

Unusually quick response to temperature change is realized through the use of shape-memory alloy.

A relief passage can be secured via bias spring even when the oil pressure has increased because of the clogged oil cooler.
At the time of low oil temperatures, oil does not flow out to the oil cooler because the thermo unit valve closes, but it flows back to the filter

through the bypass passage. When the oil temperatures rises to more than 70 degrees, the valve opens to let the oil flow to the oil cooler.

02-01-5052 Thus, the thermo unit serves to prevent the overcooling and to keep the oil at a fixed temperature.
