Yup, I have preload spacers in right now, but nothing near an inch. I have a total of about 1/4 inch preload in the front, and this is with .43 springs. Not sure I would be comfortable with much more than this. Since you are going to have the suspension reworked shortly, you might try and drop for the forks into the tripple clamps about 1/4 inch. This will push the front end higher while riding, and my be just enough to keep you from feeling like the front is lower than the back. It will, however, change your steering characteristics, so there is certainly a tradeoff. The combination of small preload spacers, and dropping the forks my just get you from now until the suspension is tuned.
