Are you going to run a wheelie bar? Take off the shocks and drop it low and run struts? If not you should. What classes do you plan on racing in? Im assuming you will be bracket racing so running consistant is what you want. You can have a stock untouched bike and run pretty good in a bracket race. Depending on what kind of classes you are racing depends on how to help you out. You will want fron smoothy tires. Will this be a track bike only? If so, remove the front brakes and run some spindle mounts. Weight is everything in drag racing so ditch everything you dont need.
