If you could have shortened your front forks, can you guess how many inches it would have been? 1"? 2"?

Also, let's say I have the newly rebuilt fork (seals were pissing oil in the package) and YZ front wheel and front brake-- I think all I need are bearings, correct? Can you tell me what bearings I need or a link to the thread which spells it out? I have read for hours and I know that the bearings are same size OD and different ID or vice versa, but I never saw something that said "Order bearing XXXX"

Aside from the ignition, what else is left to handle?

I'm ditching the BMW bars and I'll run straight MX bars with Cycra or Acerbis barkbusters. I don't have heated grips. a New Ohlins rear shock is on order as well.
I found every answer I needed here. (May take a while at the computer)

Most of the other stuff you'll need to do is fitment - filing the headlight/instrument cluster under frame to clear the larger diameter fork tubes; drilling and tapping out the lower triple and putting in some screws with lock nuts for steering stops; dealing with the front fender/horn (if you shorten the forks enough you can probably reuse the BMW fender). I didn't shorten my forks and ended up with an Acerbis motard fender ($28) and put the horn inside the plastic headlight shell beneath the headlight. It actually has a louder "HONK" now than it had before.

Also, if you use conventional bars with the BMW controls keep a dremel tool or better a finger sander to remove some from the left and right controls as the BMW bars were just enough smaller to require some reaming out to fit the ProTaper bars I installed.

Mine last fall:
