I just sold my mildly built blaster and am about to buy an 84 atc250r I'd like it to be a modded banshee killer. I already plan on a port and polish and possibly a head shave. It's going to pretty much be a full drag build. I'd like it to stay stock bore but I can change it if necessary. What parts should I plan on ordering to get the most bang for my buck. I can do all the work myself so that should cut costs quite a bit. (hopefully)
