Sheared Rubber Housing on Throttle Cable - Any Adverse Impact?

Just noticed that one of the throttle cable (comes in a pair) had the rubber housing sheared, exposing the metallic lining within the outer rubber shell.

This must have been caused by the constant abrasion of the throttle cables again the fairing/headlight stay.

Is there any adverse impact of keeping the throttle cable as it is, with the metallic sleeve exposed?

Are throttle cable replacement a lot of work? Does the fairing and tank needs to go off first?

Thanks

 

What gen are we talking aboot?

 

A tape my and zip tight them where the cable make contact.........Problem solved.

 

Mine's a gen6. The throttle cable at the end nearer to the throttle grips are zip tied to the fork tubes.
