Wow, that is hard core!

I can barley weld up EMT in to an engine stand, I have no idea how I would weld thin metal rims, much less the modern aluminum rims!

The Plans Bring Back Memories. In 1950 (11 Yrs Old) The Nabor & I Built One Like That, But A Lot Simplier. Bought A Whizzer Pulley=bolted To The Spokes. Broke A Lot Of Spokes (not Motor Bike Spokes). Welded An Offset Plate For Motor. No Brakes Or Throttle. Held Kill Button In To Slow It When Needed. Direct Drive. 3/4 Hp Briggs & Stratton Eng. Notice The Exhaust Valve Pushrod Coming Out Of Block Running Up To Rocker Arm On Top Of Head ! Had A Poppet Intake Valve (weak Valve Spring) Vacumn Would Open Intake Valve. Had To Jump Off And Run Along Side It To Get Up Any Hill. I Think Thats Why I Have Bought Many Motorcycles Since Then (power). Now Assembling A Friction Drive. The Cycle Is Almost Complete (cycle Of Life).

That made me a lil upset with myself for arguing with my Chinese engine and not working harder to build a better mouse trap. Clutch is awesome. Have been pondering some thing similar, but more of an "anti-clutch" (pull the lever to engage a belt to a centrifugal clutch, then to sprocket and chain)

Neat Times, that would make a great vehicle to tell the story of ones life and make a great book.

Dan, Its Funny You Say I Should Write A Book, Many People Have Been Telling Me That For Years ! I Have Been To Busy SERVIVING. The Computor And Word Prosessor Would Make It Much Easier Though. I Have A Tree Service And I Tell People = I Know The Saw Is Dull And Needs Sharping, But I Can`t Do It Now, I`m To Busy Sawing !!
