Anyone done engine work on the new fuel injected bikes?

I am getting ready to tear into a brand new 2010 YZ450F. Anyone done one yet? We are porting and milling the head a bit and running an aftermarket cam. Just wondering if anyone has tore into one yet and if there are any suprises. I have been doing quite a bit of work on the 2010 Honda 450s and 250s and I have to say I really like working on the fuel injected bikes so far.
