Are you going to be the one installing the new cams? if not the just ask the service tech to check before installation and call you if it is out of tolerance.
If you are doing this yourself, I'd still perform the runout measurement. I hope you have the tools needed for it all this maintenance?
DO the easy stuff first. I think Dan said it best, "Do the stuff that doesn't cost money first, runouts, measurements etc."
Go slow and double check your work. HAVE FUN!

Short answer, yes. Also, doing this during Winter is a good idea. If the runout passes, start the up grade. if it fails you have time to figure out what your next move will be.

2002 fxdx .. read up on cams and which numbers are important. Bored and polished to 95/96. I first went with the Andrews 37, I think it was, but then went to HQ-575 and couldn't be happier. Gear drive, titanium push rods, beehive springs. The HQ 575 is great in all ranges and doesn't stop anywhere. Well worth the price of admission. Oh, while you are in there, replace all the roller bearings as the originals will self destruct. My mechanic used Torrington.

Don't. Adjustables are easy. Nice to be able to set specific preload too.
