Hey y'all

I've just put new throttle cables on my 92 MC21R.
My problem is that the throttle won't snap shut when released. in fact it won't move at all unless twisted shut by hand... cruise control...
With no cables connected, the throttle shutting spring seems really powerful so i must be doing something wrong with the cables themselves, but can't see it?
Does everyone else's throttle snap shut on its own when you let go?
If you have overcome this problem yourself could you help me please??

Thanx in advance
