Thank you, DirtWarrior. They are a lot of fun. I get a kick out of doing the speed limit on a bunch of recycled junk. There's a certain pride in knowing I fabricated the vast majority of the parts myself, too. Nobody has one exactly like mine, and I dig that.
The reliability is so much better than the old china girl cruiser-then-chopper I helped construct. It was much too temperamental for my liking, so I went with old American chainsaws for my own creations. The ones in the metal cases have always been good to me, and I highly recommend them. They're pretty hard to kill.
If you have a good frame, good engine, and a good plan, one can make a sweet little ride. I did it on the smallest of budgets. In fact, most of that was spent on the speedometers and other electrical after they were already up and running. I say, go for it. My plans floated around in my head far too long, and I could have spent that time riding.
Once I built the first, I had to make another one. Be careful what you wish for. As my father used to tell me, "Work smarter, not harder".
