I have a metal tube coming out of the cylinder head and connecting to a rubber hose on the front of my bike. It is blowing a brown burnt fluid onto my lower engine case. I was told it was an emission tube. My question is, can I remove the tube and the emission unit from the bike and is there a after market fix for removing the tube and compoints. What can I use to plug the holes in the head after I remove the tube from the head?
