Drag Strip Gallery

OK Performance junkies. We've seen what you can do on the dyno, but now it's time to show what you really have. Let's get some drag strip numbers from you. Scan your time slips to send to us or we'll accept published results from AHDRA and PROSTAR to get added to the Drag Strip Gallery. Also send a quick description of the bike and tell me if it is a street or race bike. Be honest with us, cause just because it has a license plate on it doesn't make it streetable. If you can't run the engine on pump fuel or aren't willing to run it down Main Street during Bike Week, it isn't a street bike.
