This throttle cable is intended for fitment to the BSA 650 models with twin Amal 389 and 689 Monobloc carburetors and dual cable twistgrip. May be suitable for earlier model years or other applications also. This listing is for 2 cables.

Made in the US by Barnett, this premium quality cable features a friction-reducing nylon lining for easy operation and longevity. Overall length measures 44″, sheath length is 40-1/2″, with an inner wire free length of 3-1/4″.

The cables for twin-carburetor models with a dual-cable twistgrip must be individually adjusted for the correct cable lash. The slide height for each carburetor must be established, then the adjuster barrels on the carburetor top cap are adjusted to synchronize the cable pull of both throttle cables from the twistgrip throttle control. 

The carburetor top cap must be removed to thread the cable through the top cap adjuster barrel. The return spring is installed over the cable, then the cable is captured in the throttle slide. The twistgrip housing must be opened up to engage the barrel-shaped end of the cable into the rotor on the twistgrip. Refer to the workshop manual for more installation details.
