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

..... and if it's a pipe thread it would be BSP (British Standard Pipe), not Whitworth

Tomato, Tomahto... .. who freakin' "sizes" a wrench based on the DIAMETER of the bolt?!?!

Whitworth the genius who invented the thread size in the first place long before anyone else thought of standard thread sizes based on function....

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?

Is it BSP? If so any one know the size?
