Somehow this seems rhetorical.

Why? Foundationally it is a reasonable benchmark (well, starting point) for making the suspension firm enough so that the combination of the bike's weight and your weight are well-enough supported for a safe, controlled riding experience.

How? Twiddle the preload adjusters until the recommended sag is reached ... sag being the difference between how much the suspension compresses with the weight of the bike alone, and how much it compresses with you sitting on the bike.

Full setup can only be reached by also setting compression and rebound adjustors (if available) to suit your riding style and preferences, alongside fine tuning preload.

So science plus guesswork plus personal taste plus riding style plus the roads you ride.

Sounds super complicated. Is there anyone that would be willing to twiddle my knobs for a small fee?? Is it really worth it thought?

The best performance upgrade is upgrading the operating system of the operator. It is cheap, easy, fast, safe and works on every bike you will ever ride.

Yes totally worth it if you are in any way a "spirited" rider.

Probably not worth a can of beans if you are a low energy cruiser type.

We always started at one (1") inch, & progressed to fine tune f/there.

You know this...? (Surprised you asked.)

Just take it to Catalyst (CRT) or Dave Moss and for around $40 let them do a suspension set up. If you can't tell a difference, we can't help you.

Holeshot, that sag is a natural progression as you age. You have to get used to it, and learn to accept it.

None of my previous bikes had any really useful preload or any dampening adjustment. When I bought this bike I road for a few weeks with out making changes as I sorted through a few things. Once I adjusted the sag and dampening it was like riding a different bike. The handling improvement was unbelievable.

I would mildly disagree. Odds are that even the cruiser suspension is not optimized for the individual. Getting it right makes a difference.
I bounced lots of newbie bike and found a many wrong and a few dangerously so.

Thanks Ernie...at 42, I was getting worried it would get better. Missed you at Buttonwillow.

No doubt. My thinking, though, is that a relaxed rider won't notice the difference because a relaxed rider doesn't focus on performance. The handling could be better or worse, but when you are the type of rider for whom a perfect ride is purring along and just enjoying your day, unless your undercarriage is scraping, there's probably little to notice.

While there may be little to notice by some riders, there are significant improvements in safety with a properly set up suspension v. a not properly set up suspension.

Even if the rider doesn't think they need or will notice the difference the suspension set up, they do benefit from it.

why... because you dont know what springs u have installed, how much total preload is placed on those springs, nor what range of springrates work for your bike. once all those 3 are known, measuring or knowing sag is superfluous.
