You need to vent the crank case and the rocker cover, may need a small filter on the catch tank to equalise.
If you still have loads of crank case presure could mean rings.

I've retained the standard casing, but removed the valve itself. I run 2 lines one from the crankcase and the other from the head.
No problems during the trackdays I've done.

My ST170 breathes pretty heavy as well. Way more than the old black and silvertop zetecs I used to run. I think they all do. Good catch tank
essential.
