Most of my driving is around town so I put my valve next to the master cylinder figuring I would never need to adjust it once it was set. In hindsight, I wish I had put it in the cockpit and will probably move it someday.
To adjust, I started with mine fully open (no proportioning - rear tires locked up first). Kept adjusting a couple turns at a time until the front locked up first. Then I kept fine tuning (back and forth several times) until I could get all four lock at the same time. The whole process took less than 1/2 hour and was very simple to get it dialed in.
Good luck,
Gene
