Re: Throttle cable housing shortening . . .
You shouldn't need a new ferrel either. What I always do is take a lighter, heat the ferrel a bit and pull it off gently with a pair of pliers, then set it down somewhere I won't step on it. After I cut the cable housing, I slide the ferrel back on, then heat it again. This heats the plastic, which kind of "glues" the ferrel on. Let the ferrel cool completely before installing the cable.
