After looking at those pics again, it looks like you can take that breather tube from the case and attach it to where you installed the block of plate for the EGR.
This is called a pair sucker mod, its usually used on 2002 + GSXR 750's and other race bikes and typically costs around $2k+, but it was as easy as just attaching a hose for $1 and gaining 12hp. What it does is creates negative pressure inside the case removing all the air so the oil can flow without friction. I would have to do a test on this motor to see if the pair sucker mod would work but if it does it would 100% add at least 1hp and make the engine run a lot better.
