Now we have gotten some good input from people that have actually raced these bikes and others that have them, drilled and not drilled. What I w ould like to know is what is the most likely guess as to who was doing t he drilling: Seiber, John Eisenmann (importer) or the local bike shop? I t seems to me that there are too many that are drilled which seems unlik ely considering the fact that track riders considered it heresy to drill . So maybe they came from the plant that way. I have no idea, but since it has come up, I'd like to know. Eddie, feel free to jump in. Jerry Jeter, Wildwood, MO USA
