So I was greasing my steering head bearings (they were loose just like you said Greg) and I saw that there is two positions that I can set my tripple clamps to. One the is one forward set of holes and one set slightly back. Mine are set in the back ones. What difference do they make on the different holes?

Do you mean bar positions? lol. Does the bike have adjustable caster (is fork rake angle adjustable) doubt it somehow but my bike has adjustable caster on forks. it's a matter of pulling out a kind of eccentric shaft and turning it 180 then re in stalling in steering head. Changes fork angle from 18 to 20 degrees.
Do tell ... ?

Im guessing you have after market clamps these holes are just for bar possition front holes for tall riders and back for shorter riders or people who like their bars in their lap..

Since the ’06 models, an offset axis is adopted for the handlebar bracket on the YZ450F/250F. This made it possible to select between two different (forward and backward) handlebar positions by turning the bracket handle bar holder forward and backward.

For the ’09 model, two attachment holes are provided on the handlebar crown (holder). This makes it possible to select between four different handlebar positions by combinations of the bracket handle bar holder side (forward and backward) and the crown side (forward and backward). This increases the forward and backward range of adjustment to enable settings that accommodate a wider range of rider preferences, course layouts and track surfaces.

Yamahas been on to this for a while.

When I got my bike the bars where positioned in the rear holes. I hated it! Really cramped me up. Its really surprising how much difference moving them only the 20mm or so makes. Its personal preference though just try it and see what you are comfy with. I put bar risers on mine as well! Barty is correct you can turn the risers at the mounting points to give you 4 different positions all up, if you have them!

I have special 6 days triple clamps on mine with the 18° and 20° adjustments but have left it as is (and I don't even know what its on) until I can sit down with Danger when he does my suspension and find out exactly how the different settings will effect handling! Then set it up properly to what he reccomends. I'm just riding it, like I stole it, till I can afford to do the lot!! I hazard to guess it has something to do with quicker turn in/front end nervousness vs straight line stability/headshake at top speed etc.
