Been lurking for some time. lots to see and read.
I plan to fit a 160cc two stoke Victa lawn mower into a modified pushbike frame with suspension front and rear.
It will be a bit out there. I am developing my own centrifugal clutch to handle the power.
using 3 pocket bike clutches on a keyed shaft and will rev out to 6000rpm.
I will be porting the Victa and fitting reed blocks and an expansion chamber.
I want to build this for under $200 as I have a bet going with some guys from my old church to build and race around a paddock. I have a few advantages as I have a lathe and access to a mill.
I am also interested in building a hand Cycle.
