Jet needle adjustment (XX 125 version)

On the carburettor used in the

XX 125

the main nozzle is

of non-removable type and therefore cannot be replaced.

Therefore, adjusting the carburettor requires changing the

pin.
The pin adjustment parts, which have the same taper angle,

are available in different straight part diameters and different

taper start positions.

Standard pin: NYCF

If the retainer position number is the same, changing NYDF

to NYEF has the same effect as raising the retainer position

by 0.5.

A. Rich

B. Lean

C. Initial position of the taper part

D. 0.5 groove variation

Relationship with throttle opening

(XX 125 version)

The flow of fuel through the main system of the carburettor

is controlled by the full jet and then further regulated by

the area between the atomizer and the taper pin. In the

relationship between fuel flow and throttle opening, fuel

flow refers to the diameter of the straight portion of the taper

pin around the 1/8 to 1/4 throttle opening, while the 1/4 to

1/1 throttle opening refers to the initial position of the taper

and the position of the clip.
Therefore, the fuel flow is balanced at each stage of the

throttle opening by a combination of the diameter of the

straight portion of the taper pin, the initial position of the

taper and the position of the clip.

A. Lean (larger diameter)

B. Rich (smaller diameter)

1. 1/8 throttle

2. 1/4 throttle

3. 1/2 throttle

4. Fully open

5. NYDF-3 pin

6. NYDG-3 pin

7. NYCF-3 pin

8. Main nozzle
