I don't think the guy on the Delphi forum meant you to "raise the front" of the bike.
I am sure what he meant was to raise the fork tubes in the triple trees by 15mm.
I made new dog bones that are 15mm longer than stock & raised the fork tubes in the triple trees by 20mm. I used a vernier caliper to ensure both fork tubes were raised by the same amount
Your first reply had it right.
