Throttle cable question
Might be a rookie question? - I installed Kuryakyn grips on my 2007 FLHTCU – things went smooth but now the throttle doesn’t close on it’s own – The grip moves very free & doesn’t appear to be in a bind – Is there a spring on the end of the throttle cable area that might have came off or broke or is there an adjustment?

There is a specific sequence for adjusting the throttle and idle cables. It's laid out in the service manual for you.
It's a simple process. You need to remove your air cleaner so you can access the throttle wheel on the fuel induction module.
Your throttle cable is the one closest to the front of the bike, looking at the handlebars. The idle cable is the rear-set one.
Pull back the rubber boots, and loosen the jam nuts. Back the adjusters out all the way (full slack) on both cables. With the handlebars straight ahead, turn the grip to open the throttle all the way, and hold it open. Then turn the cable adjuster to take the slack out of the cable, and until the throttle wheel (on the throttle body) just hits the stop. Add another turn to the adjuster, and lock it down with the jam nut.
Then turn your bars all the way to the right, and take the slack out of the cable with the adjuster. What you want is for the cable housing to just contact the spring that's inside the cable guide on the throttle body housing. If the throttle returns to idle smoothly, tighten the jam nut down. You can play around with the adjuster a turn or so either way to get the best response. Cover the adjusters with the boots, reinstall the air cleaner and go for a ride.
No special tools required, it takes 20-30 minutes or so, including r&r on the air cleaner.
