Hello all- I stumbled upon this forum while researching the chinese engine kits, and trying to figure out weather or not to go that route. Looks like a lot of good information and good people! The bike I started with is an old Schwinn with a Dixie 2-speed an a LOT of rust- My dad bought the bike 30 years ago, and for the past 25 it has been behind the garage. I pulled it out, flipped the bars, oiled it, stuck a skinny off of my parts bike on the front, and a new tube and tire on the rear: I rode it around town for a while that way, then got the wild hair going on. I put my bike together the first time as a front-wheel-drive gizmo using some old model airplane parts. I used an old Supertigre .40 from my pile o' parts, along with a tire from one of my models to form the drivetrain. I built a mount that hung on the springer fork tine on the left out of 1/8" aircraft-grade mahogany ply with basswood as a filler. For a fuel tank, I had a few martinis to finish up a bottle of vermouth, and stuck a slice of brake line off of a Volvo 240 in it for a pickup. I ran a piece of hose from the muffler to the "tank" to pressurize it and allow the tank to be mounted slightly below the engine.
