That would be strange since this engine originally came with a valveless crank vent system (and therefore would've been vulnerable to puking massive amounts of oil into the intake from the factory), but it's possible.
I was curious what was under the cam cover and discovered that the tube for crankcase ventilation goes through the head and right down to the crankcase-no wonder is sucks in all kinds of oil! Yet the factory manual shows just a simple hose going from cam cover to air box. I'll figure something out when I get back from Springnationals.
