Yes very cool moped. It looks in very good condition. Maybe the good people at Treatland sell and deliver a big bore kit for that engine. Maybe they sell heavier rollers for the variatior to give you less torque and more top end. I’m not positive but I thought all mopeds were just under 50cc. Am I right about that? What is the wheel size and I am also curious about the cc and make of the little “mosquito”?

it’s a piaggio and it’s a 50cc and i will probably get heavier rollers for less torque as well

there’s a couple shops in the area for tuning these types of mopeds and i’m going to stop by there and see what they have

Seeings how you're miles closer to Italy for parts and I'm guessing that these bikes have a big enough following in Eastern and Southern EU that shops are around that do some business in moped tuning and repair. As I recall Tomos mopeds are pretty common in the ex Yugoslavian/SE Europe countries and have quite a tuner population for these little motos and mopeds.

I'd look more deeply into the road going legality of a bigger carbed, bored and piped moped, IIRC some European countries will not let their mopeds be larger than 49 cc's, and might even have top speed limitations.

Heavier flyweights will make the CVT start changing ratio at a lower RPM, that will effectively make for less torque but it won't actually make the overall total gear ratio taller. And what you'll find is your bike will accelerate slower. I'd rather set the flyweights so the engine is in the best part of the torque peak in RPM, so you can accelerate quickly when you really need to.
 
On my shifter bike the reduction range is 66.79\1~16.25\1. I'm a large person and live in a mountainous region. There's been times I've gone by mopeds riders using throttle assist to help push their mopeds up some of the 30% grade hills. On the steeper hills I may only be doing 8 mph in 1(1) gear at 7000 rpm, but at least I'm riding up them.

Just be aware of this, if it is a 50cc engine, you're a large rider, and have steep hills to contend with. A few engine mods isn't going to help much. Things like changing out the CVT weights/springs isn't going to make a big difference if you haven't lowered the ratio reduction. If you have lowered the reduction ratio; it's also going to lower your top level ground speed.

The only true way to get steep hill climbing abilities and maintain the same level ground speed using the same engine is to widen the reduction range. The way I was able to do this on my bike is I have a triple chainring shift kit.

I used to work for Piaggio at their factory owned shop in San Francisco. That's a model we didn't have over here. Ciao, Bravo, Grande are the ones I remember. All restricted to 30 mph by law so the carbs were tiny and so was the exhaust pipe. Very simple engines but reliable. I replaced quite a few bronze wrist pin bearings and decoked a lot of mufflers. There was no room for a larger air box because the little engine was a tight fit. One of our customers rode a Ciao from Florida to San Francisco and back.
