I use a briefcase size Craftsman set (168?) pcs. I also use a Harbor Frt. lift. I put the bike up, open the tool case on the floor, and grab few other tools as required from the rollaways. 90% of the tools needed are 1/4 inch 8mm, 10mm, 12mm deep sockets, phillips and flat screwdrivers, 2 inch extension, and needlenose pliers. 18 mm deep 6 point for the sparkplugs. A bench vise is handy.
If you can weld, you can probably make a decent substitute for the special tools.
I also use a lot of beer, or a ton of beer depending on the job. lol
