Im looking for some advice/help on making and putting on a oil catch can on my 2006 r6, im building a race bike for next year
Many companies sell racing bodywork for that bike. Just get one with an full bellypan and there you go.
I use a clear fram paper-element fuel filter inbetween the crank case and the airbox. By doing this I am still able to get a negative crankcase pressure and the paper filter element keeps the oil from getting into the airbox. I can also see how much oil has accumulated inside the clear filter and change it out when it is starting to get full.
