ADJUSTING CARBURETOR 化油器調整

a. To set the high speed needle: (large needle sticking out from the carburetor body), turn the screw as pictured. Initial high speed
needle setting should be 3~3.5 turns (close the needle completely, then back out 3~3.5 turns). Clockwise turn will provide leaner
setting (lower fuel to air mixture), and counterclockwise turn will provide richer setting (higher fuel to air mixture).
b. To set the carburetor idle: (small needle sticking out from the carburetor body), turn the screw as pictured. Initial idle setting
should leave 1mm carburetor gap. Clockwise turn will provide higher idle (larger carburetor opening), and counterclockwise turn
will provide lower idle (smaller carburetor opening). For more details about the engine setting, please refer to ENGINE BREAK-
IN/SETTING procedures to properly set the engine.
c. To set the low speed needle: (The low-speed mixture screw is located in the end of the carburetor). turn the screw as pictured.
This screw controls how much fuel enters the engine at idle and low throttle. This adjustment will smooth the idle and improve
the acceleration to mid speed. Make this adjustment with the throttle closed, after setting the idle. Turn the screw clockwise gently
until it bottoms out. DO NOT over tighten. Now turn the low-speed mixture screw counter-clock 6 1/2 turns.
d. Remove the outer foam from filter and make it moist evenly with a few drops of fuel. Put the filter in a plastic bag and knead it
until the foam is saturated, but not soaked.
e. Finally, make sure the air cleaner boot is securely fastened with a zip-tie.
Never run your vehicle without the air filter .If the vehicle will be operated in an area with fine dust, use filter oil or caster oil instead
of fuel. It is important that the foam is only moist to trap dirt and allow air passage. With the foam too wet, limited air can pass through;
therefore, limiting engine performance.
a. 高速油針調整：調整高速油針（突出於化油器本體之較大螺絲），如圖示。於調整前應先保持油針於開啟3~3.5圈的位置（油針完
全鎖緊後再鬆開3~3.5圈）。高速油針順時針旋轉，化油器將會呈現較為貧油設定；逆時針旋轉將會呈現較為富油設定。請參考引
擎使用手冊來設定您愛車的引擎。
b. 怠速設定：設定引擎怠速轉速用螺絲，突出於化油器本體之較小螺絲（如b圖示），於調整前注意化油器應保持1mm的開口。怠
速螺絲順時針旋轉，怠速轉速提高；逆時針旋轉，怠速轉速降低。請參考引擎磨合建議來設定您愛車的引擎。
c. 低速油針調整：調整低速油針時需卸下上半部車殼（低速油針位於化油器本體末端） ，如c圖示。於調整前應先保持油針於開啟6.5
圈的位置（油針完全鎖緊後再鬆開6.5圈）。正確調整此油針可讓怠速與中低速更加順暢，調整此油針時需將油門關閉，以及怠速
設定完成後。
d. 原廠搭配的高性能空氣濾清器，建議您於使用前於濾清器上塗抹適量濾清器專用油，可加強過濾粉塵，避免進入化油器造成引擎損壞。
e. 最後確認固定濾清器之束帶是否確實綁緊。
引擎請勿於未安裝空氣濾清器情況下運轉，並且注意濾清器的清潔工作，以避免造成引擎的損壞與壽命簡短。建議使用適當的濾清器
專用油，強化過濾的功能。
