What are you, a masochist? Most of us want to avoid discomfort. :mrgreen:
Anyway, start with a plan. Build the plan as acquiring knowledge, skills and tools in stages. Leave welding bikes for later though you can acquire a welder for learning and practice whenever space and money allow.
You say you don't know much about building bikes? Start by getting the one you have running like a champion. Not extra horsepower, just running the way Honda intended. (No matter how beautiful a creation you ultimately build, if it doesn't run worth a crap then it's just yard art.) Then move on to appearance. Get your bike looking beautiful. Not exotic. Maybe not even fancy. Better than a piece of crap. (Your words, not mine.)
When you're done with your bike, buy another. Maybe some barn find or a garage queen covered in dust. Make it better than the bike you have now. Sell it or trade it then do it again. And again. Each time, look for new challenges that provide opportunities to learn something new. Buy new tools for each project.
When you've gone through a couple, maybe even half a dozen, then your plan should have you thinking about the exotic creations of your dreams. Maybe you've taken a couple of classes at a local community college along the way that will make it even easier to create those beasts. Or maybe you're dedicated to learning everything "the hard way" because you're much more of a hands-on learner. Doesn't matter because you've built that into your plan. But it all begins with a plan.
Good luck!
