"Snappy" Feel to throttle????

So recently I have seen some videos of some older bikes (85 or so) that sound and look really "snappy" on the throttle.

I used to own a 2000 CBR F4 and that was a carbed bike and the throttle, and overall bike, was very responsive to throttle movement (flick the wrist, pin the RPM's)

I figure it must be involved in tuning the carbs correctly. I have an '82 GS 450, just put UNI pods on. Re jetted to 145 / 17. Bike runs great right now. But what part of the carbs should i tune to get the throttle to be more responsive?

Different Jets?
Play with mixture screw?

Any and all ideas/help is welcome and appreciated.

get them synced.

Awesome! Thanks man. Ill give this a go.

GS twins will never be as responsive as a high revving 4 cylinder. To add to the problem, the carbs are CV types designed to be smooth and they are slow to respond, plus they don't like pods which make response somewhat worse.

I'm not suggesting that it can't be improved. Just letting you know upfront that it will never be a bozosoku bike.

It's also got really heavy flywheels that take a while to accelerate
Crank is probably 10lbs heavier than CBR600 one
