Shocks
The length of a quality shock is in the box, when set up properly, is 1/3rd of the stroke (a generalization) shorter when you are sitting on the bike when set up. You do not loose that 1/3rd of the stroke as when riding in the real world the road surface is not flat, it goes up and down. The shocks must be strong enough to control the bike and not rely on the springs for being part of the suspension. The springs only make the bike and all of its contents weightless as far as gravitational pull goes.
Talk to Howard ^^^ at Motorcycle Metal. He'll do you right. My inseam is an inch longer than yours, and with a seat mod by Mean City Cycles and Ohlins as rear shocks, I'm flat footed with a slight knee bend when sitting on my King.
A pair can be had in most INDI shops that horde take off parts. You will need the fork caps also as the cartridge damper rod screwed into the fork cap. Remove the springs & replace them with ones that are the proper rate. Than remove these crap pistons with the spring as a blow off valve and replace them with real pistons with compression & rebound shims. The HD cartridges are used in many applications and are now sold as HD premium suspension which is very far from the truth, look like this:
The 20mm piston is very crude and has a spring & a washer for valving This system is only meant to slow the dampening mostly one way. This system can be improved by R&R the piston with a 20mm Ohlins piston and the advantages are it has a Teflon replaceable piston ring for rebuilding, HD has a permanent one. The Ohlins piston has a compression & rebound shim stack that can be re-valved to the riders personal needs. They look like a miniature one of these:
On my web site I give a step by step installation video under Buell, yes, almost the same basic cartridges with slight differences.
