I have posted in the welcome forum. Here is my 1st post outside
I have been riding motorcycles for about 25 years and do lots of travelling.
Have a group of friends who meet regularly. decided to have a scrapheap challenge. Rules are quite simple.
The Challenge
Get a Pushbike and fit an engine . . .
It must complete 10 laps around a track set up on a mates 40 acre Property near Parkes in Australia.
It will have a Sand trap, water hazzard, ploughed paddock.
Must be completed by the end of the 2008
We will also include a hill climb event as well.
Rules
You must:
1. It must be cheap . . . $200 limit and you must document the build.
2. Can use any engine that you are game for.
3. Start with a pushbike frame
4. Use pushbike wheels
5. Have working brakes Front & Rear.
6. Use the front and rear sprockets of the bellcrank, but can remove pedals.
7. Use the pushbike chain. It must be fitted but you can use another for drive
8. Send pic of frame before you start.
9. You can invite friends to be involved. The more the merrier.
10. Hopefully with video the carnage.
So Far I have a Victa 160cc 2 stroke engine and picked up an old mountain bike and a set of Manatou 80mm forks for the front.
I have worked out the swing arm design with a motorcycle rear shock. Where the motor will mount. I am going to run an expansion chamber and M/C carbie.
As the rules state, I need to use the bicycle chain and drive. So I will position the motor on the RHS and run the reduction drive in the LHS.
I just need to work out how I gear the motor down from 5000RPM to 26" wheels at 80kph (45MPH) Belts of chain & gear reduction?
I will attach pictures as it develops.
meanwhile here is a Victa 160cc 2 stroke in a BMX frame.
