I use zip ties for mine - but not to secure the cable. I used one of the lifting eyes on the motor in front of the throttle linkage to put a zip tie through leaving it about a 1 inch loop. This forces the cable into a friendlier path to the linkage - without restricting it's movement.
If you believe something to be true, it will be - in it's consequences.
