You can find Cucciolo engines in Europe quite easily but they cost money and go fast for an old 4stroke.

It's possible to place an old 10mm carb on a Mobylette engine and hold the performance down as well. They can fit within the frame, it's how the Genuine Fake is being built, except I'm going 12mm unrestricted.

Default I once had Oil Spill tires too.......

I once had Oil Spill tires too- my new name for Beach Tires-

I was calling them Old Indianapolis Wasp tires-

Still have the same bike I first built w/the same 66 motor from '08 but it's changed incarnations a bit, including the alloy 34 sprock directly bolted to a high flanged flip/flop hub

the orange 50 has a custom GT 39 front sprock, drilled and hole enlarged as the back motor drive.

The silver 66 will do 35 but cruises best between 25-3o. At 62 I don't want to fall and either of these builds could do with a tamer motor.

Don't get them out much anymore, but great weather now- riding my road bike on the Baldwin Path in Jacksonville- beautiful!

below- micargi 66 with "oil spill" tires, then 1.75 street and finally 27 x 1 1/4 wheels

Here's an interesting thread about the Garelli mosquito 35 cc motor and some videos at the bottom and on youtube:
http://thecabe.com/forum/threads/197...osquito.88045/

I guess these are available, but I don't think they're still made

There was someone in Germany recently selling new build Mosquito engines, but at a price you can get a new 50cc scooter for. There's also this Polish company selling a roller drive kit for over the rear wheel:

Second hand Mosquitos and several other brands are widely available in Europe, including the Sachs designed Spartamet engine and hub design at 28cc.

Well bike berry is selling a 38cc friction drive here for a fairly low cost- I just don't want an over the wheel friction drive. I want a 33 cc China Girl that weighs half as much as a 66.

It's a shame all the hub motors or hub mounted motors are this side of the water, Cyclemaster/Rabeneick or BSA Winged Wheel or Spartamet sound like the ideal size and power for what you want.

I like the idea of smaller lighter and quieter, but it will be harder to sell the idea of less displacement to the US market. Most jurisdictions specify less than 50cc and 20mph so there are pretty good target goals. So how to make it smaller lighter and quieter?

A large weight reduction is in the flywheel. Aluminum cheeks with steel weight rings on the outer diameter could reduce weight 3-4 lbs in a standard China Girl. Thinner precision casings and plastic covers would take 2-3 lbs off and reduce all dimensions 1" in every direction. BMX chain and aluminum sprockets. These things would double the price of production.

The plastic gear and chain covers would dampen a lot of their noises. A new air filter cover and fine foam filter would quiet a lot of the intake noise. Rubber pegs between the cylinder and head fins would quiet those noises.

The exhaust would be a pipe tuned for max torque at 20mph and +50% over-rev so extra pedaling would be rewarded with up to 30mph speeds but still meet the legal 20mph condition on flat and up hills. Ideally the torque tuned pipe would be thinwall construction with a surround type muffler to quiet it to a whisper.

The beauty of this approach is that each component would still interchange with all the 50cc and 66cc motors that are still out there. Development could start as aftermarket sales of individual components as a complete package is developed.

Think about it;
meets all legal requirements, 50cc, 20mph flat speed
will haul touring weights up hills
can still pedal or down hill to 30mph
whisper quiet
half the weight due to precision thinwall castings and aluminum/steel hybrid crank
1" smaller in all dimensions
Complete interchangability

Will someone build this?

The only people likely to make it are hobby builders, not commercial suppliers. I looked at ways to chop a strimmer engine down but it's not realistic.
