NOTE:
Before making any carburetor jetting changes verify that:
o
You are using the proper fuel and oil
o
The fuel is fresh and uncontaminated
o
The oil and fuel have been mixed in the proper ratio
o
The carburetor is clean (no plugged jets)
o
The air filter is properly clean and oiled
o
The float height is within proper specification (proper measuring technique
is described later in this section)
NOTE:
Perform all jetting changes on a motorcycle that has been warmed up to
proper operating temperature.
The carburetor on your Cobra
motorcycle is quite adjustable.
Figure 59 shows its range of
adjustment and in particular what
adjustable component affects what
range of operation (specifically
throttle position).
FUEL SCREW ADJUSTMENT: Adjust for maximum idle speed
The fuel adjustment screw is located on the left side of the carburetor. It is the
smaller of the two adjustment screws and requires the use of a small flat blade
screwdriver for adjustment. After adjusting for maximum idle speed, use the idle
screw to adjust the desired idle speed.
NOTE: If the fuel screw requires more than 3 turns out, replace the pilot jet for
one that is one size richer (larger number) then re-adjust the fuel screw.
