This is a build I had finished a while ago. I had used a Starfire Super Rat GT5 engine. (Not many super rats imported) I also used Harley Sportster fuel tank. Won't need to stop for fuel often with that 2.2 gal. tank! I also had tried something different with rear disc brakes. (disc brakes standard on Spoiler) Since I needed a rear drive sprocket as well I decided to use rear sprocket for brake disc as well. I used a 36 tooth front crank sprocket that was flat & drilled my own holes for mounting to wheel. relocated rear caliper lower so it wouldn't interfere with drive chain. (as seen in pic) Brakes worked as good as always. Just had to be very careful if lubed chain. Brake rotors don't work well if lubed as well! lol. It turned out to be a fun bike to ride. Chain & engine alignment couldn't have worked out better. I thought I would post this & share some ideas if anyone had plans on a Schwinn Spoiler build. Thanks, Dan
