I've heard it many times: "my throttle moves a little too much before this or that happens". It's there for a reason. The slop is called free-play, and is an intentionally added amount of movement before engagement to prevent damage or a dangerous situation. Try turning your bars all the way to the left and wiggle your throttle with just two fingers. Next, turn your handlebars all the way to the right; notice how much less the throttle moves. When your bars are turned all the way to the right, your cables are in the most bind, pulling on the cables just a little bit. I've ridden motorcycles with throttle cables adjusted too tightly, and it is a scary thing when the bike revs up while making right hand turns. If you're not expecting it, it can cause a crash. On the flip side, too much free-play can cause the ferrules to fall out of their slots, causing an unusable throttle.
When you adjust your throttle cable you want to have the bars turned all the way to the right so the throttle cables are in their tightest position. With both of the adjuster screws turned out you want to start adjusting the throttle (forward-most) cable first, and the idle (rear-most) cable second. Turn in the throttle cable until you hear a positive "click" from the butterfly in the throttle body (or carburetor) when you twist the throttle as far as it will go. This click means that you are getting 100% throttle movement. After you get the click, turn in the idle cable until you get 1/8-3/16" of "wiggle" or "free-play" in the throttle. You also want it to have a quick "snap-back". "Snap-back" is the speed at which your throttle returns from 100% open to 100% closed. If one cable or the other is adjusted too tightly, your throttle will move back slowly. If your cables are adjusted correctly, you will hear a positive click on closing as well as opening.
Know that when you bring your bike to Latus Motors' service department that we will use factory specs to adjust your cables, to the tight side or the loose side if you request it, but we will not adjust them any further from recommended. Doing so can cause harm to you, and your safety is our largest concern. Always have your service manual open when doing any maintenance on your ride. It could be the difference between textbook perfect and your buddies laughing at your not-so-handy work.
