Pictures of this bike on Duccutters are bigger.
Strange routing indeed : the lower H valvecover has a line going up, joining at a T the line that exits from the side of the H cylinder and runs to the back where it goes into a T with one end exiting the side of the V cylinder and going into the LHcover.
Nothing going to the RH side.
About the pegs : maybe this bike was designed for a RaymondRoche type of guy
Standing on the pegs and stretched out to the bars
