Idle speed adjustment

The idle speed should be set at  1400 ± 

100 RPMs
To adjust the idle speed: 
1.  Locate the idle adjustment screw (1)    

located on the carburetor.  
2.  Allow the engine to warm up 

approximately 10 minutes
3.   With the engine running, turn the idle 

adjustment screw in or out at small incre-

ments until the correct idle is achieved.
Note:  A service center can perform this 

adjustment .   A diagnostic tachometer is 

required for this adjustment.

Inadequate  throttle play can be 

hazardous
The engine speed could rise when 

the handlebars are turned if there 

is not enough throttle play. This 

could result in loss of control.

  

Always check throttle play before 

each ride. Turn handlebars from 

side to side making sure throttle 

does not increase when doing so.

Throttle Cable adjustment

The hand grip throttle freeplay (2) should 

be .078 - .24 in (2-6 mm) 

To adjust freeplay

1.  Loosen jam nut (3)

2.  Turn adjusting nut (4) to proper setting

3.  Once throttle grip is at the proper 

freeplay,  re-tighten the jam nut (3). 

.078 - .24 in

    (2-6 mm)

It is important that the throttle grip have a 

certain amount of freeplay so the throttle 

does not rise when the handlebars are 

turned from left to right.
