that’s a tough one... there is Tommy Dawson in Transfer he’s north of us but sells parts, karts and cuts a mean tire... I normally just use JC Specailty. Is there something in particular you need done?
Sprint there are a ton with Royale, J3, Dan Sclosser can get you anything you need, David Kalb and a little west is Brandon Adkins. Dirt, you don't have much unless you go all the way up to Jay Groves and kartwerks. Maybe there is someone around Morgantown?
