New project idea.

He has emailed me what needs doing:

"Must-do:
- Fix kickstart by grinding casing so that kick start mechanism lines up properly with kick start level. At the moment it is just out and it slips.
-Tune carb to run with the 100cc engine. I thought I had the correct main jet size but this may need to be changed. Currently running with No air filter, so either keep this or get some pod filter foam.

Optional:
- Get battery and reattach to electrics
- Get a split throttle cable or jimmy something up to use the oil pump. Bike is currently set up to run premix. But has the ability to run with the oil pump.
- Re attach attach some plastic fairings and wing mirror.
- Mount new rear brake shoes (I have these already)

That is all I can think of at the moment. Only other thing to mention is that the speedo doesnt go cos there were no where to attach it to when I put the new front suspension and wheel in. This also means the odometer has read 6674km for about 2 years... haha."

So taking into account that I am a relatively novice mechanic, is it a good idea to take this project on? are these jobs relatively easy to do?

To be honest if your going to use it on the road find a :

close to home.
Mucking around with small engines is fun, cheap, you learn a lot if your not familiar with engines. I know of a scoot with a 70cc water cooled cylinder conversion goes just over 100kph before its final drive gets upgraded (they go 140kph in Germany)
Go for it if your racing around a warehouse with a few mates with similar projects but unless your into tuning all the time its not going to be a "start it and ride" scooter its out of its rego class for the road and its hard to vin a modified moped. You can at least get it up to WoF standard eg all the lights brakes tyres etc.
Your speedo will be a problem but a push bike computer will get a WoF

in saying that...

The jet should be fine if its the standard carb, its running premix so some of the volume the jet has is lost to the oil mixed with the fuel, in theory its lean. If you put the oil injector pump back in the system check that its working before draining the premix.

The carb needs a pod filter or std filter the engine runs lean with the extra volume of air available doubling the problem with premix.
I'm not sure why the casing should need to be ground down perhaps a washer under the cupped castle shaped kick starter receiver (?) will bring it further out rather than grinding down the casing.

You can't push start a cvt scoot so anything that makes it more reliable away from home should be done.

The rest is up to you, if your just racing around a track I wouldn't bother with the plastic.
