Hi folks, got really motivated at Bairdco's race last month, so I motorized my 1980 Schwinn Spitfire. If my laptop wasworking, i'd post pics. But, its not sooo...I'm a big fan of briggs & stratton engines, so that's my pwer plant. 3.5 hp with a mikuni 22mm carb, stock exhaust(for a lil while) pirate cycle hub adapter with 44 t, a jackshaft setup, and a china tank. like the title says, woot, its way faster than I thought. I should be at the Grange race, to CRUISE, work any bugs out. just took first test ridelast night. I'm VERY pleased with the newest incarnation of my bike,The Grey Ghost. The search here is pretty awesome, if you spend the time. I found pretty much all the info I needed to complete this build. This is a blast to ride and FAST! LOL
