I believe that it is designed to capture some combustible fuel.You say it is a problem and I say it is not.I believe it does pass gas fumes to the air box for 99% of it but at high speed some fuel falls out of suspension and that is one of the jobs of the stand pipe...to collect it.That is my theory FWIW.
But I have enlisted the help of a guy who could probably clear this up,
Joe Berk of CSC.He rode 5,000 miles at 8,000 RPM's(also the name of his book he just wrote)With Zongshen engineers riding along with him and I'm thinking he may have some insightful info into this.
I have not seen him on this forum but he does frequent the ADV rider thumper section under our bike.
I went on there and posed the question to him so maybe we will get an answer beyond the speculation.
