Well I've been a long time watcher and am now embarking on a rather strange project which may interest you.
A bit of background about me I run a motorcycle event in Australia called the scrapheap adventure ride which raises money for the Down syndrome community. I have been running that for 14 years and with the generous help of the scrappers have raised over $1.1 million.
I also have 2 artificial legs as I was run over by a train in 1976.

I have built a number of scrappers over the years including my XR460/4 and my Suzuki RV125 running a PE175 motor.

I also like to build other silly bikes and this is what I would like to share discuss and gather information with the group.

I recently purchased a complied Suzuki FZ50 frame which I want to run bicycle components on and ride to central NSW to an event I run called the Silly Buggers Ride. This is like Scrapheap, without the fund raising.
3 day ride for slow bike, lots of dirt

My Plan
I would like to run an 85cc 2 stroke engine with a Jack shaft and use the derailleur gears. I will be using a expansion chamber and quiet muffler. Open to suggestions as well. Reliabilty is a key consideration, so whilst tuned for torque wont be for top end power
Additional items on the wish list are electric start, a way too charge a battery and run lights and blinkers. I won't be riding at night but that will be a requirement for registration.
Motored bicycles are illegal in Australia.
There are so many items I need to get my head around including wheels tyres. I need tyres that can ride on dirt roads covering a distance of 762 kilometres each way over 3 days. in warm conditions. . . .
I will build a cradle that will bolt to the FZ frame and carry the engine, jackshaft and the swing arm pivot and rear wheel.
Plenty of head scrathing, designing and planning in this thought bubble.
