I bought this little bike just before Christmas, browsing the web whilst sat in the departures lounge at Heathrow on the way to a job. The sale of my car was taking ages and getting me down, and I wanted something to keep me occupied.

I picked it up a few days later. I couldn't ride it because I didn't have a bike license. So I renewed my CBT on a Wednesday just after Christmas, then passed my full bike test on Friday after one day of training
So I rode the bike about, but 49ccs wasn't getting me anywhere except inches from the bumper of car behind.
So I ordered a new engine. Whilst I was waiting for it to arrive, I re-painted the number plates as they had been done by billy bodge-it.
Out came the 49, and in went a chinese-made 107cc clone on the Honda bolt-pattern:

I also increased the drive sprocket from 15 to 16 teeth, to stop it throwing me off the back, and increase the top-end speed a bit.
Then came days of mucking-about with electrics. I'm colour-blind, so this bit was really frustrating. As the old engine was 6V, and the new one 12V, I fitted OEM indicators with homebrew LED internals, and an MSA rainlight into the OEM tail light. The headlamp is original, with a 12V bulb.

After a while, success! http://www.youtube.com/watch?v=tbXTRynfyHA
After that, it was a case of removing the ugly double seat (not even correct for the bike anyway), and fitting a single seat from Thailand. All of the parts you'll ever need for these bikes are remanufactured in Thailand, including some cool aftermarket stuff as well.
The single seat required a new bracket to be welded to the tank. I got a pro to do this as I didn't want to die.
And this morning, I took it out for it's first proper run. It's fantastic - tops-out at around 50mph and gets there about the same speed as a small hatchback, so you don't get hassled by other road users. It's a bit noisy - the muffler is designed for a motocross bike and isn't that effective, so I will have to sort that out.
Here it is, pretty-much finished:
