I know you are on a budget, but will tell you what I have done so far on my bike. It's not a Cafe Racer, but some of the parts will work. Purchased used HD mufflers & shocks from a local HD dealer for a low price. Had a local muffler shop to bend aluminum/steel connector pipes from the headers to the mufflers. My H box was in poor condition. I did not install a crossover pipe, but like Gary said, will need to. Will rejet the carbs, too. Installed Kenda Challenger tires. Used stock length cables with bikemaster European handlebars. Used HotWingGlass seat pan, seat pad, fender, & rear brake light assembly. Used 54MM pod air filters. Will need to replace the front fork springs & rebuild front caliper. Purchased a new master cylinder off of ebay for $50 plus shipping, will see how it works out. Traded & purchased parts with other members of the forum, too. Have done more than mentioned above:
