My home made minibike

[rudolph]

I made this a few months ago, I bent up a frame from tube in a normal pipe bender, wheels are 4" I started with a 5HP Briggs&Stratton engine but found a 8HP Tecumseh from an old industrial vacuum, I have made a jack shaft so it has 14 teeth on the clutch, 17 on the input and 11 on the output and 37 on the rear sprocket, it dose about 30 MPH and will throw you back on the seat and spinn the rear tire, its 300CC with all bottom end power,

I have started making a 2nd bike, and I plan on making a batch of 6 small frames to use up some of the engines I have, I have alot of B&S Tecumseh and Kohler engines.

Cool project. Looks fun.

The execration is amazing but top speed isnt much, I realy want to get my hand on a Briggs & Stratton Vanguard V twin for another project, I have a couple big Kohler K341 550cc single but its a bit on the heavy side as its got a cast iron block, one is in an old garden tractor and if you drop the clutch in that you will brake your neck.
