Throttle return tension

Throttle return tension
How much return tension do you have on the throttle? If you open up the throttle and then let go, does it "snap" back under good spring tension from the carb return, or is the return a bit more sedate/sticky?
I'm having a bit of trouble getting the cables right - whenever I drop the tank down on top the throttle basically sticks. Runs ok when the tank is lifted. I'm in the process of getting some light oil down the cables to make sure they are nicely lubricated.
Otherwise the cables seem to be routed correctly. If I shim the tank up at the front fixing point by about 5mm it seems to be OK (which I might resort to yet).
Any thoughts or suggestions? Its a 88/89 FK.

Same here, doesn't snap back at all.
I did however, on the weekend clean the twist grip on Mrs SB's bike by removing it completely, cleaning the bar which had umpteen years crud built up - linished it lightly, very light smear of grease, oiled the throttle cable and vióla a throttle that snaps back.

Funny you mentioned this as I just installed the Vista cruise throttle lock And it was very tight without being adjusted down (IOW basic form sized). So I had to enlarge the inner diameter and when I did enough for the throttle to be loose enough I noticed it didn't want to move on it's own anyway! LOL
So since IIRC the throttle spring is on the carbs and I'll be godamned if I'm gonna pull them again this month!!!!!!!!!!!
It's, staying the way it is!

Thanks everyone, managed to get it sorted tonight. Turns out the problem was the frame wire guide by the front tank mounts, where the two cables are guided through.
The guide was squished up a little bit tight and was making the cables feed upwards before being pulled down over the frame and under the tank. Sort of causing a little hill for the cables to go up over and back down again. It was enough to really make the whole mechanism bind up.
So I loosened up the guide - now its a fairly straight dive under the tank and its all good now.
I haven't started the bike for nearly 4 months now while I've been doing a bunch of maintenance (and its been winter) so that was pretty much the last thing sorted until it runs again. Then got a carb synch, fluids & filter and a shake-down run into central otago to meet kiwi-tk for a beer.
Thanks for the help.
