Properly sized throttle cables are essential for safe and correct adjustments to the throttle and carburetor. This throttle cable is used from the throttle twist-grip to the junction block and is suitable for the US-specification T140D and T140E models with twin Amal MK2 carburetors. (2) lower cables are used in the original throttle cable assembly. This listing is for (1) upper cable.
This premium-quality cable from Barnett features a threaded barrel adjuster at the twist-grip end, as well as an inline adjuster. A friction-reducing nylon lining contributes to easy operation and longevity. Overall length is approximately 30-1/2″, sheath length is 28″, with an inner wire free length of 2-1/2″. Made in the US.
The cable is pulled by the motion of the twist grip, allowing it to raise and lower the throttle slide in the carburetor. The upper cable adjuster is threaded directly into the twist-grip housing, with the lower nipple fitted to the internal sliding fitting of the junction block, which is controlled by the movement of the single upper cable from the twist-grip. Fine adjustments to cable lash are made by the inline adjuster on the cable and the barrel adjuster on the twist-grip housing.
The twist-grip end is fitted to the rotor in the throttle and switch gear housing. The junction block must be opened to allow the upper cable to be positioned in the internal sliding fitting, while the lower cables are fitted to the lower end of the sliding fitting. The junction block is then screwed back together with all (3) cables forming an assembly.
