Crankcase breather

[Dennis]

How much oil should blow out a crankcase breather tube?  Particularly on a small twin, like my cb350?  I don't think I overfilled it but I may have.  Anyways, there is more than a mist blowing out.  If I crack the throttle a few times ( a minute or so) a small puddle forms on the floor.

On my Chang, the crankcase breather vents to the air box, and it is very susceptible to overfilling the crank case with oil.  Any feedback would be appreciated.

I use the Breather to Oil my Primary chain on the Panhead.....although this past summer it appears like that was not enough
Not familliar with the CB350...but...to me, a small puddle sounds excessive..

I think those are Fast1's favorite engine to work on.....he probably would know
Should be someone else around who have run these bikes....

My kid has a CB350 and I had one many years ago, don't recall anything noticable coming out the breather hose. Won't be able to get to it for another month or two to check again, my yard is wet and it's tucked away in the back of my shed. Will fire it up when things get nicer around here, the aftermarket pipes make that little twin sound nice.

My 400 vented into my airbox-secondary chamber-then out the bottom of the airbox, didn't notice any oil. I had to re-shape the airbox to accept the pod filters so I zap strapped the breather tube over the drive chain, didn't really help with lubrication as not much oil came out.
