It's an easy job to do, but I have done it before. I have a fix my hog dvd
for the sportster that I had. seeing someone take apart the controls was
very helpful. if you have a service manual it helps also. you will need to
loosen the throttle and idle cables all the way to remove the cable ends from
throttle grip, and then need to readjust them once everything is back together.
that's the most critical thing i would guess, and that not hard to adjust either.
just make sure when you turn the steering far left and right that your idle
does not change. you will need to remove the air cleaner to see the throttle
arm stop. this is all explained in the manual.
there is lots of help on doing this job on various forums, just do a search.
