Breva 1100 throttle cable adjust

[tris]

I'm trying to adjust the throttle cables and am finding something a "bit strange" IMO

I've been backing both cables all the way slack and at that point the throttle snaps shut very satisfactorily

When I firstly take the slack out of the closer
a) I use every bit of the adjustment available
b) the throttle action stiffens up

I then have to barely move the opener

Is this simply that the cables (35k miles) are worn or is there something else going on.

I believe that the opener is 1120mm long (110mm free length) while the closer is 1125mm long (100mm free length)

Could they have been installed arse about face originally 

PS
This is the 1st bike I've owned with twin cables so I might be just cocking it up

Sussed it 

 I slackened both cables of fully and then tightened them both up evenly to minimal free play.

Voilà no more snatchy pick up from a closed throttle

Happy Days
