Rough low down pull away, emulsified oil overflow

Having read the thread, i wondered if this is another case or something else?

I too, have had what looks like oil emulsion dripping from what appears to be one of three breather hoses teathered together. Only covered 50 miles, nothing very aggressive. I'll call Norton tomorrow and find out more.

Why would it be emulsified? Combustion process? Air cooled so wouldn't be head gasket alignment? It does run very rough on pull away and tip in / tip out in 1st gear. Wonder if they are linked?

Emulsion caused by cool running,short rides or poor breathing. Go faster for longer!. If the oil in the motor looks milky change it. Aircool motors are are always too cold or too hot,which is why most are watercooled with thermostatic control.

Hi Robert. thanks for your response.

Whilst running in, it could well be that I haven't 'driven faster for longer' at all! I'll work on that.

On talking to someone else offline, it seems that emulsified oil drip is common on most air - cooled set ups with dry sump. On reflection the drops are more watery than oily. This is probably oil vapour mixing with water extracted from the air and channeled to 'breath' into the airbox sump, not through through the air filter itself.

The oil in the oil tank is clean and the level is just above the lower mark on the dipstick.

I am pretty sure the other drivability issue i am seeing is not linked to the emulsified oil, but more likely , one of fueling or not enough of it at throttle off conditions.When I decel in gear, I slow down far to quickly (without even the rear brake light) I wonder if Norton canmap the calibration to account for this and add a bit more fuel, than currently, to make this situation safer, and smoother.

I will ask this question today.
