My neighbor who has built a 6 and Rocket, commented on how I could make an improvement on my purchased 9A. I was concerned on the minor oil weeps in the engine compartment. He pointed out that as the breather tube is, it is pressurizing the case. If the tube were extended down and pointed rearward, this would create a negative pressue and most likely illiminate the weeps. It would be a quick fix. Your thoughts?
