Here's my entry....a hacked up Broncco TX-??
So, the lookers will note that I'm not doing my usual Tecumseh for this build...as this is a bearing Briggs flathead.
Here's the tic list:
Frame: 5.5" stretch to fit a tall boy like me.
Sprocket and Caliper: 70t #35 with the sprocket machined to accept a DB30 style caliper.
Swing Arm Mount: to accept jackshaft and swing arm (which may be stretched).
Front Springs: internals dumped for external springs.
Seat: by manchester1.
Clutch/chain Guard: Custom aluminum
Fuel Tank: 2 qt kart fuel tank shrouded by an custom aluminum Broncco look-alike
And the fun:
Engine: Ungoverned. ARC Piston Rod, ARC Billet Flywheel (fixed at 30 degrees), 18# Springs, Dyno Super Stock Cam rated for 6500. Billet Lifters. Re-jetted Chi-Kuni 22mm Carb. Shaved eyebrows, etc.
I have the original rims with Pirellis in great shape. A few other mods up my sleeve, but we'll see what time I have this spring.
BTW, the poster is patterned after an old "patent medicine" advertisement from the late 1890s, I thought it would be cool to do.
