venhill q/a throttle

hi all,
just purchased a venhill quick action throttle.
has anyone fitted one of these to there bike and if so
is it straight forward to do?
my concern would be that the q/a has only accomodation
for one cable where as the bike has two cables to the standard throttle assembly.
do i need to use the pulling cable only and remove the other?

thanks again steve

That's about the sum of it, don't know how well they work on the SV though. Let us know would you
