that may be all you';ll have to deal with. Brand is not too terribly important, the needed parts are all pretty universal for karts. Frame makers , even for racing frames, often just add "stock" spindles , brakes, pedals, wheels, sprockets etc. everything you need to complete this is at OMB warehouse, go power sports, vegas karts, azusa , and a dozen other kart suppliers all across the country. Just start living at the websites of thos various suppliers, and you will accumulate ideas and parts to assemble the frame. Just decide ..is this for pavement or dirt.....then go to work in that direction. Many of us here are in favor of dirt, hills sand and rocks.
