I've got my crank case breathing through a vertical 30cm piece of hose terminating with a small pod filter. This means the pressure that occurrs in the cases equalises with the atmosphere...
Is this the optimum arrangement?
Does the case require a negative pressure to draw fumes out? (as per the original set-up were the breather went into the air box benifiting from the low pressure developed by the carbies)
Is there any time during the rev range that a bit of pressure is required?
Does any of this make a scrap of difference or am I just spending too much time under the house stareing at my bikes engine?
