So I am new to the newer bikes as I have a 76 FLH. So when I twist the throttle the butterfly in carb doesn’t open fully, and it feels like throttle doesn’t open all the way, bike seems to ride ok and run ok. Just feels different than what I’m used too. It feels like when it his that cruise control wires is where the throttle grip stops? If that makes sense! And maybe this is normal!

thanks for any help!!!

 

If the butterfly is not fully opening you need to adjust the throttle cable.

Get yourself a service manual, best money you will spend on your bike.

 

Your cable is worn out and needs to be adjusted. Its kind of an art....

You want the throttle cable to JUST kiss the throttle stop on full open and the return cable to have just a HAIR of slack when fully closed. I dont usually promote the 'go read a manual' attitude, but this is one operation that's covered pretty well.

1. Slide rubber boot off throttle cable adjuster mechanism.
See Figure 1-20. Holding cable adjuster with a 3/8 inch
wrench, loosen jam nut turning in a clockwise direction.
Back jam nut away from cable adjuster until it stops. Turn
cable adjuster clockwise until it contacts jam nut. Repeat
procedure on idle cable adjuster.
2. Point the front wheel straight ahead. Gently turn the
throttle grip so that the throttle is wide open (fully counterclockwise)
and then hold in position. Now turn the
cable adjuster counterclockwise until the throttle cam
stop just touches the stop plate on the carburetor/induction
module. See Figure 1-21. Release the throttle grip,
turn cable adjuster counterclockwise an additional 1/2-1
full turn, and then tighten the jam nut against the cable
adjuster. Cover cable adjuster mechanism with rubber boot
3. Turn the front wheel full right. Turn the idle cable adjuster
counterclockwise until the cable housing just touches
the spring in the cable guide (as seen through slot).
Work the throttle grip to verify that the throttle cable
returns to the idle position when released. If the cable
does not return to idle, turn the cable adjuster clockwise
slightly until the correct response is achieved. Tighten
jam nut against the cable adjuster and cover cable
adjuster mechanism with rubber boot.
4. Verify that the throttle control operates freely without
binding. With the tension adjuster screw backed off, the
throttle grip must freely return to the closed (idle) position.
The throttle control also must open and close freely
when the front wheel is turned to both the right and left
fork stops. If the throttle grip does not return to the idle
position freely, check the adjuster screw tension (if
present). If the adjuster screw is backed off, inspect the
cables for short bends.
