Throttle cable?

[Listerine]

On my way back from work yesterday, I found that my bike was revving quite a bit on right hand corners but fine on lefts. After a bit of digging about, it seems that the throttle cable is the culprit, possibly pinched on something or a bit tight/worn. Is there a visual clue to use to determine if the cable just needs adjusting or replacing?

Bike is a 99 Bandit 600 and it's done just over 6k miles if that makes any difference...

I have seen people mention lubricating a throttle cable I've not got the faintest on how to do things like this...

Cheers!

I did play with the adjustment under the handlebar but to get the setting I needed, the cable was ridiculously slack so I didn't want to leave it at that. The 2nd half of the cable to the engine seems fine so it must be pinched somewhere.

The cable's 13 years old so I suppose there's no harm in replacing it. Is it a straightforward job with low chance of mucking up the right tension? I'm trying to see if I can actually do this myself rather than throwing every problem to the garage to fix.

My concern is that the situation arose quite suddenly rather than a gradual one, so something could have been quickly damaged?
