2.3 FUEL TUBE

Inspect the fuel lines for deterioration, damage, or leaking,

and replace if necessary.

2.4 THROTTLE OPERATION

Inspect the hand grip for smooth full opening and

automatic full closing in all steering positions.

Inspect for deterioration, damage, or kinking in the throttle

cable, and replace it if necessary.

Disconnect the throttle cable at the upper end. Lubricate

the cable with commercially available lubricant to

prevent premature wear.

The BEAMER R2-50 uses a manual choke. Check that the

choke opens and closes smoothly. If it does not, check the

wire connecting to the switch.

2.5 THROTTLE CABLE ADJUSTMENT

Slide the rubber cap of the adjuster off the throttle

housing, loosen the lock nut, and adjust the free play of

the throttle lever by turning the adjuster on the throttle

housing. Inspect the free play of the throttle lever.

This free play should be 5-10mm.
