Figuring Ride Height

[ulakovic22]

Hey guys, I have a quick question about getting to your ride height. I have D2600 bags and the bag height is supposed to be between 6-9 inches. I've also looked around and I know PSI is personal preference but most people like 80ish in the front and 35ish in the back.

Getting the stance right in the back seems pretty straight forward. My thought it to figure out where is rides best and then use a lowering block to get the stance/ride height back down to where I want. My question comes on the front. How do I lower the front back down once I get the ride desired? Currently I'm have a 67 with disk brake upgrade from a 71, everything else is stock. My thoughts on options are, drop spindles or cutting the cups on the bottom a little. I'm guessing that cutting the cups though will lead to issues with the bag touching the lower control arm and I'll have to modify those.

What is everyone else doing to get their ride height and ride preference in line?
