Planning to do the breather mod for the final drive on an R80 G/S. I plan on using the old breather with the center section knocked out. Then press in an insert a banjo bolt fitting from a brake line can be used to attack an old brake line for the breather hose. Not sure where to put the terminating end and if it needs some sort of filter or valve on the end. I'm thinking of terminating it in the airbox. Ideas and input are greatly appreciated.
