[T3] Two questions about throttle cables

[David Sanderson]

Hi Folks
I have a couple of questions about throttle cables. First, the  
throttle cable in Matt's notch broke. Actually, it had worn through in  
two places - just where the cable exits the tube by the pedal and  
again at the rear where it come through the fire wall. Did these  
cables come with some sort of nylon sleeve to prevent this kind of  
abrasion and subsequent breakage? I've looked at the parts book but do  
not see any such protective sleeve. I see at CB Performance that they  
sell a cable that is in a  sleeve - that should do the trick I think.
Second, I imagine that it is very difficult to get 311 721 551 A, the  
protective tube and grommet (311 721 573) for the throttle cable from  
the pan to the firewall. Have people tried other kinds of tubes, like  
bicycle parts as a substitute?
Any thoughts would be appreciated.
Thanks
Dave
