X-TREME XG-470 Owner's Manual page 12

WARNING!
Never start the engine without the complete clutch cover assembled!
Otherwise the clutch can come loose and cause personal injuries.
In the Carburetor, fuel is mixed with air. When the engine is tested at
the factory, the Carburetor is basically adjusted. Further adjustment
may be required from time to time, depending on climate and
altitude.
The Carburetor has two possible adjustments:
1. Idle speed adjustment
2. Air/Fuel Mixture adjustments
Note: Standard idle RPM is about
2500-3000 RPM.
WARNING!
When the engine is idling, under no circumstances should your XG-
470 be moving.
If the XG-470 continues to move after idle speed adjustment,
contact X-Treme or your local X-Treme service center.
Idle Speed Adjustment
1. Start the engine.
2. Using a long Philips head screwdriver,
gently turn the top screw clockwise until the
XG-470 starts to move forward. (Fig. 9)
3.Then back out by turning the screw
counterclockwise until the XG-470 stops.
*Correct idle speed is obtained when the
engine runs smoothly just below the RPM
when the XG-470 starts to move.
Air/Fuel Mixture Adjustment
1. Start the engine.
2. Using a long, standard screwdriver and
while holding the throttle wide open, turn the
bottom screw (with spring) clockwise as far as
possible, then back out 1 & ¼ to 1 & ½ turns
until the engine runs smoothly.
