Would someone with a bike please tell me the size (OD) of the fitting coming out of the engine fro the crankcase breather?

Thanks,
Eric

I must be missing something. I have a "L" shaped black plastic fitting that will turn through a full 360 degrees. No nuts are bolts involved. When I replaced my Crank Case Breather hose, I didn't need to measure anything, just used flexible vinyl hose & heated the end with a butane lighter & pushed it over the end. Didn't need to pull out my Whitworth wrenches. so what are we talking about here?
