throttle/idle spring

[section8joe]

Is there a way to adjust the spring tension on this spring? please disregard the broken throttle cable connector I took the pic from a different thread.

I'm using a lowbrow throttle and a 650 central throttle cable and it's adjusted all the way out. My bike idles a little too high and if the cable had like 1/16 of and inch of slack and everything would be fine. If i push the throttle return with my finger I can get the bike to idle right where I want it to.

Not really, that spring is plenty tight the way it is.
If your careful you can cut a 1/8 or so off the cable housing with a Dremmel tool and a cut off wheel.

Mine was the same way. I resorted to removing my throttle blades and re-centering them on the throttle shaft.
