Remove the secondary valves of cylinder head and relational parts, then plug the each
holes.
Remove the oil receiver and plug the hole.
Remove the air cleaner element or cut the cleaner element off remaining punched plate
to reduce the air flow resistance.
1. Remove the parts.
2. Plug the holes.
3. Replace with plugs (92043-1506), and plug the holes.
10
Cylinder Head
Grind off the stepped portions of the ports and smooth the inside of ports to make
intake/exhaust gas flow more smooth.
Grind off the stepped portion only at the mating surface between the carburetor holder
and the intake port. Do not port it. To extend the intake port, air flow speed will be
reduced and the engine performance at the high speed range may be down.
Mark the carburetor holders so that they can be installed in their original positions.
Grind off and smooth the stepped portions at the mating surface between valve seat and
the port.
Smooth the inside of the intake port and exhaust port.
Use the hand grinder.
Use #200 oil stone for eliminating any stepped portions.
Use #200 oil stone for smoothing and #300 oil stone for finishing.
NOTE
These procedures make air resistance less and intake/exhaust gas flow more smooth.
However, much more effect can not be expected by excessive grinding and smoothing.
It may be done to the extent of getting rid of uneven surfaces.
1. Stepped Portions of carburetor holder and cylinder head.
2. Stepped Portions of valve seat and cylinder head.
11
The combustion chambers are modified by cutting work but the edges shown must be
hand finished for smooth corners (Round them to about R1).
Chamfer the machining edge of the cylinder head where the valve seat is installed, also
smooth the dome of the combustion chamber with the valves installed. Excessive
smoothing may reduce the cylinder compression.
XXX. Edges
NOTE
When grinding the cylinder head bottom surface or using thinner gaskets, adjust the
valve timing to keep that the valve to piston clearance is not less than the minimum
value (IN: 0.8 mm, EX: 1.4 mm).
Camshaft Chain Tensioner
Replace the cam chain tensioner with the kit to gain the durability.
Apply the engine oil to the tensioner rod, O-ring and tensioner body, insert them into the
tensioner body.
Check to see that the tensioner rod turns freely in the body, if not, polish the tensioner rod
or fine the female threads in the body with a tap (Diameter × Pitch = 6 mm × 1.0 mm).
Install the tensioner on the cylinder block with the tensioner rod is fully pushed back.
Turn the tensioner rod in with a screwdriver until it becomes hard to turn.
Turn the crankshaft clockwise forcing lightly to the tensioner rod with twisting force to
take up any gap and tighten the locknut.
Tighten the rock nut after adjustment.
NOTE
Never forward the tensioner rod forcibly, this will increase mechanical loss of the
tensioner and may damage to the chain guide.
The cam chain tensioner must be adjusted at every race.

Original Timing Cam Lift Valve Clearance
Intake 288° 8.30 mm 0.13 ∼ 0.19 mm
Exhaust 266° 7.50 mm 0.24 ∼ 0.31 mm
If you don’t adjust the valve timing for racing, install the camshaft sprocket to the kit
camshaft using the round bolt holes and adjust the cam chain timing according to the
Ninja ZX-6R Service Manual. If you adjust the valve timing, install the sprocket to the
camshaft between the adjustable range of the long bolt holes.
Tighten the camshaft sprocket bolts to 15 N·m (1.5 kgf·m, 11.0 ft·lb) of torque.
Valve Timing (when the round bolt holes are used)
Timing (cam lift center) Intake Exhaust
Original 105° 110°
Race use 105° 110°
When grinding the cylinder head bottom surface, grinding the cylinder top surface or
using thinner gaskets, be sure the valve to piston clearance especially.
When using the sprocket long bolt holes and adjusting the valve timing to be different
from the standard timing, check the valve to piston clearance of all cylinders after
adjusting the valve clearance correctly.
Valve to Piston Clearance (Min.)
Intake 0.8 mm
Exhaust 1.4 mm
If the valve to piston clearance is less than the minimum value, do not start the engine
because the valves will touch the piston and the engine may be damaged.
Measure the valve to piston clearance at about 12° ATDC (Intake) and 11° BTDC
(Exhaust) of crankshaft timing. At this point, the valve to piston clearance will be
minimum.
Valve Springs
The original machine’s valve springs should be used
.
Cylinder Compression
To adjust the cylinder compression, adjust the thickness of the cylinder head gasket and
the cylinder base gasket or smooth the cylinder top surface to make the piston squish
0.65 ~ 0.8 mm. Keep the piston squish more than 0.65 mm.
Position the piston at Top Dead Center, and put a small piece of modeling clay on the
shoulder of the piston. Install the cylinder head gasket and cylinder head, and tighten
the head bolts to the specified torque.
Remove the cylinder head and measure the thickness of the clay. The thickness of the
collapsed clay is the size of the squish.
Squish Measurement
[1] Front and Rear 0.65 ~ 0.80 mm
[2] Left and Right 0.67 ~ 0.85 mm
The most preferable squish measurement is [1] 0.65 mm/[2] 0.67 mm.
Select proper cylinder head gasket and cylinder base gasket.
Note that by grinding the cylinder head surface only left and right squishes become
narrower, while by grinding the cylinder top surface or decreasing the gasket-thickness
all the squishes become narrower.

Connecting Rod Bolts
Use the original connecting bolts and nuts.
The original connecting rod bolt has recesses at both ends to measure its length and
determine the bolt stretch.
Install the original bolts into the connecting rod.
Before every tightening, use a point micrometer to measure the length of the bolts and
record the values to find the bolt stretch.
Apply a small amount of molybdenum disulfide grease to the threads of bolts.
Tighten the big end nuts at the torque of 11.8 ±2 N·m (1.2 ±0.2 kgf·m): reference
Check the length of the bolts and find the bolt stretch.
Bolt Length after tightening – Bolt Length before tightening = Stretch
Bolt Stretch
Usable Range: 0.33 ~ 0.38 mm (0.013 ~ 0.015 in.)
Turn the big end nuts more until the bolt stretch reaches the usable range.
NOTE
Replace the original bolts with new ones if they have already been tightened up to usable
range 2 times.

Clutch Adjustment (Back-Torque Limiter Setting)
The Ninja ZX-6R engine is equipped with the Kawasaki back-torque limiter mechanism in
the clutch. The back-torque limiter works to reduce the chance of rear wheel hop caused by
engine braking during hard braking and down shifting. The back-torque limiter operating
condition can be changed by changing the total thickness of clutch plates and changing the
number of leaf springs. Try different settings and select the best.
20
The standard setting of length [A], total thickness of clutch plates shown in the illastration,
becomes about 40.7 mm. For this setting the effective stroke of clutch spring plate during
the back-torque limiter operation is adjusted between 0.45 and 0.75 mm. By increasing
the effective stroke the back-torque limiter causes more slip. The effective stroke
increases by decreasing the length [A]. The length [A] between 39.5 and 40.7 mm is
available by changing the combination of the steel plates. Replace one steel plate with a
thinner one and try the setting. If the operation of the back-torque limiter is not enough
replace other steel plates one by one.
* Steel plates of former model’s are available.
Thickness (mm) Part Number
2.0 13089-1073
For precise setting the measurement of the effective stroke of clutch spring plate is
recommended.
• Remove oil from clutch plates.
• Hold an extra drive shaft in a vise and install the following clutch parts on the shaft.

• Engage the cam followers (Clutch Hub) with the cams (Sub Clutch Hub).
• To measure the effective stroke of clutch spring plate, set a dial gauge [A] against the raised
center [B] of the clutch spring plate.
• Move the clutch housing gear back and forth [C]. The difference between the highest and
lowest gauge readings is the amount of the effective stroke of clutch spring plate.
[D] Drive Shaft
After installing the clutch to the engine, measure and record the depth [B] shown in the
figure on page 21 and 22. The length from the clutch spring plate to the top surface of the
sub clutch hub, using a caliper or a depth gauge. Manage the depth [B] to adjust the
effective stroke after that, because the friction disks would be worn and the length [A]
(Total thickness of all clutch plates) would change. The decrease of the depth [B] from
the initial setting shows the increase of the effective stroke of clutch spring plate from the
value initially measured.
When decreasing the length [A], total thickness of clutch plates, use the optional spring
retainers (provided as optional production parts) to keep the preload of clutch springs
according to the table below. If you have clutch slip during acceleration use shorter
spring retainers by 1 mm to increase preload of clutch springs.
When decreasing the length [A], total thickness of clutch plates, use the optional shim
(provided as optional production part) to keep the position of clutch release lever
according to the table below.
The standard setting of the number of leaf springs is four. By decreasing the number of
the leaf springs the sub clutch hub operates easily and pushes the clutch operating plate
causing more slip. Two types of nuts are available for the number of leaf springs, two and
three. They are provided as optional production parts. The number of leaf springs affects
all over the operation of the back-torque limiter but especially the beginning of the
operation.
