This one would give you a run for your money. It's got a license plate on it now because I have a friend at the inspection station (LOL), but it was my drag bike and knock off 10 second runs. I once blew off a Pantera with it, and had a passenger on it at the time too!

Back tire is a foot wide, full race cam, ported and scuffed heads (works better than polishing on shovelheads), 5 angle Manley valves, solid lifters, full race .550 lift cam, 2-1 custom headers, forged 12:1 pistons, S&S stroker crank and overbored, Accel electronic ignition, S&S racing carb, Barnett race clutch and 5 stud basket, 5 speed Revtech trans, etc. etc. and the motor was built by a guy who used to run top fuel Harleys. With the sprockets in it now, it tops out at 143 mph at the 7000 red line. Very few Harleys will rev even to 6000 RPM's. It has embarassed many a Jap bike rider - much to their amazement.
