How effective is this set up for ventilating the motor, or is it one of those better then nothing at all set ups. There is one on each side of the motor.
That's a good question, i don't know how well a one tube vent would work. But i bought a set of Zoomies from Bowler/Doug that he had on his 34 woodie willys and he ran a seperate set of tubing to all 4 tubes, very intresting and very neet.
