Smoking Breather at Startup

This might be an obtuse question, but I have my breather tube routed to the rear of my bike, right by the rear tire. Whenever I started the bike, I was noticing smoking on the right side and assumed that is was coming from the exhaust, which had me wondering about leaking valve guides and such. Eventually I noticed the exhaust was fine, and it was coming from the breather instead, which makes me wonder about several things. I assume this would be normal? I haven't modified the cases with a breather valve to reduce crankcase pressure or anything. Does anyone know if that mod would have any effect on this phenomenon? Not that it's any big deal, and the smoking quits after a few seconds. I'm just curious.

My breather on my B44 smokes on startup, as have a clear tube I can see its steam not smoke as the water condenses. Check to see if its steam or smoke.

No worries.
