☆ Shift down operation may be difficult due to“individual differences”in stock gear shiftspindles.
If such a phenomenon(shifting difficulty) is
occur due to“individual differences”it isnecessarily to modify the gear shift spindle
arm slightly to fix this problem.
(See illustration)
Also, there is a large clearance between thestock shift spindle and the crankcase(gearshift spindle) mounting part. The position of
the gear shift spindle cannot be determined
unless the cover is attached.
It is possible to visually check with the our
special clutch cover kit (02-01-0150)
installed.
When using a stock R.crankcase cover, visualconfirmation cannot be performed.
R.Check method is shown on the right fordifferent crankcase covers.
Please confirm with the check method andproceed work with the installation.

Using our special clutch cover kit◎ When using the Takegawa special clutch coverkit (02-01-0150) Temporarily assemble the shift
drum stopper plate COMP. (without attaching theshift drum plate.)
Attach the gear shift spindle to the crankcase.
Attach two dowel pins to the crankcase, attach
the R.crankcase cover gasket, and temporarily
assemble the R.crankcase cover.
Set the gear shift at 3rd speed and check thepositional relationship between the pins (ofthe shift drum stopper plate) and the shift arm(of the gear shift spindle).
● It is good position when the pins (of theshift drum stopper plate) and the shift arm (ofthe gear shift spindle) are shown as Fig. 1.
Now remove the R.crankcase cover and proceedwith the actual assembly work.
● Caution:When the pin (of the shift drumstopper plate)and the shift arm (part of thegear shift spindle) are in the position shownas Fig. 2, it is necessary to modify or replace
the shift arm.
How to modify the shift arm (of the gear shiftspindle).

COIllustration

If the pin (of the shift drum stopper) and thearm (of the gear shift spindle) interfere witheach other due to“individual differences”(of the gear shift spindle), the pin and arm
do not get caught and the downshift operation
cannot be performed smoothly. In such a case,
it is necessary to cut the shaded area.

Figure 1

Figure 2※ The position of the gear shift spindle cannot
be determined unless the crankcase cover isattached.
Caution:It is not possible to confirm thecorrect position without thecrankcase cover attached.

☆ How to modify the shift arm(of gear shift spindle)・The tip of the shift arm of the gear shiftspindle need to modified.（About 0.4mm）
Please modify the shift arm slightly asshown.
Please modify it little by little (cutting
too much, may cause different troubles.)About 22.4mm
About 0.4mm○ It incorporates a gear shift spindle, andtighten assembled the drum stopper holder bysocket bolt.After assembly, it will assemble
the gear shift spindle.

When using stock R. crankcase cover◎ Visual confirmation is not possible when using
stock R.crankcase cover. To check ,R.Crankcase
cover needs to be attached once.
Temporarily assemble the shift drum stopper
plate without attaching the shift drum plate.
Attach the gear shift spindle to the crankcase.
Attach two dowel pins to the crankcase, attach
the R.crankcase cover gasket, and temporarily
assemble the R.crankcase cover.
Make sure that smoothly shift to each gear
while rotating the counter shaft.
● If the shift operation can be performedsmoothly at each position, it is not necessary
to modify the arm.
Remove the R. crankcase cover and proceed theassembly.
● If the arm (of the gear shift spindle) does
not return properly when shifting down(a phenomenon that causes a pin on the stopperarm), It is necessary to modify the arm (partof the stock gear shift spindle).

Note:If you do not modify this, the gearand speed sensor will come into
contact and will be damaged.
Note: Be sure that you protect thespecified torque.
