Under normal conditions one can feel the little bit of slack in the cable that must be there, maybe 1/8" when you turn the twistgrip with the engine not running.

There is no need or reason for anybody to disturb these cables under ordinary conditions, to adjust the valves, etc. The cables on Bill H's '88 are still in place and working like new with no attention in 105K miles (so far).

If you look at the adjustments and work the twistgrip you will see what is going on here. You see the cable pulling the throttle open. The adjuster increases or descreases the amount of play in the inner cable. The 'return' cable is there only for a safety feature in case of a binding throttle, but does not do anything under normal conditions. But the return cable also has to be in adjustment, so that it does not interfere with the operation of the actual throttle cable that opens the throttle. Check and lube both of them, and they should last a very long time.
