A bicycle would work well with a 33cc 4 stroke + turbo.
A 49cc scooter would work wonderful with a turbo. It could actually make the thing useful in traffic.

I don't know about the vespa, but on any chinese scooter, and motorcycle I haven't had any adverse effects on mixing oils.
Not even on my Honda Shadow VT750

I think most 12V batteries sold online have a BMS installed within them.
A BMS protects from overcharging, and makes sure the battery gets charged optimally.
It's necessary, because a car's stator does not have a BMS system, and the battery will be charged via the 2 poles, so BMS must be on board.
As far as batteries, my battery of my TaoTao ATM50 actually lasted 1,5 years. It still works, but if it doesn't start from the first start, it fails to start any subsequent starts.
I've even had LiPo4 (non-iron) fail after 1 year (they still had 75% left after the first year, and less than 50% of charge left after 1,5 years).

The rollers on a 50cc vs a 50+cc BBK should be the same, because the variator is mainly RPM based on these scoots.
The more power of the larger BBKs will allow you to accelerate faster, and reach top speed much faster, but at the cost of lower MPG. Top speed should not be significantly faster with the BBK; unless you change gears.

About the additives used in oil, they are not a problem. Most oils have similar amounts of similar additives, no additives are canceling each other out, or affecting each other's behavior.
Is like doing dishes with 2 different types of dishsoap, or laundry with 2 different types of laundry soap. It'll still work well.
About the mixing, it takes a LONG time for oil to settle (heavy on the bottom, light on the top) once they have been mixed.
However, as soon as the engine goes into motion, the oil gets stirred, and since it's oil with oil mixed, they will bond on a molecular level; so you will have no real problems with lighter oils layering on top of heavier ones, for more than perhaps 10-15 seconds at engine startup; which really only helps a better startup if the effect was there.

Yeah, sure, however you still need at least 4 or 5A for your scoot to start it; I don't think it's comparable to a 2,5a at all; other than that a LiFePo4 battery usually lasts 4 years, vs 1 year for a Lead Acid battery.
They're much better, and as long as you aren't living in the hottest place on earth, and your scoot won't short circuit anywhere, they are great replacements of Lead-Acid batteries.
They last longer. I would only buy one if your scoot is relatively new; not to make it outlast the scoot.

The only thing you got to guard yourself against during engine break-in is high RPMs.
Don't get your engine into high RPMs if you're doing the breakin.
Heavy load seems to be fine (fast acceleration), just no high top speed, or 8k RPM while accelerating from a dead stop. Yet another reason not to change rollers until the engine has at least 500km on it.

diesel engines and old harleys with 75-100k miles on (or more) use 20W50

mixing oils can't harm at all.
In fact Mobil is one of the leaders on oil, says it themselves on their website, and who goes against the knowledge of a big company, who has been in the oil business for many decades, like theirs?
Anyway, no harm done in mixing, but your oil is too heavy for your scoot.
Depending on how many miles you have on the scoot, you should not go higher than 15W40.
Reasonably new scoots, with less than 10k Miles on them should do with anywhere between 5W30 and 10W40 (that includes 10W30, 5W40, or any mix in between).
You really mixed the heaviest oils. If you had put 3/4th of 20W50 in there, I would say, add the remaining oil with 0W20, and it would be ok.
Now I'd have to agree with above poster, redo the oil change.
You could capture the oil, put it in a bottle, fill your scoot with 50% of that oil you just captured,
and buy a bottle of anywhere between 0W20 and 5W30 and add it to the oil you have in there.
Mixing 0W20 with 20W50 in a 50/50 ratio should give you 10W45, which is rather on the thick side, but should work.

The pre-2003 models looked great, after that, they look more modern.

38PSI is not overinflating it. My Tao came with stock tires that handle upto 40PSI, even if the manual says 35PSI max.. 38PSI has been working well for me, since they deflate very slowly (in about 2-4 weeks to 29PSI). Unfortunately, or lucky, however you may look at it, I don't use no rubber at all  |

Mine was a 63cc, you can know if you're going faster than 45MPH on a long stretch with engine warmed up, and tires pumped up. Most if the 50cc's don't surpass 40MPH, perhaps do 42 tops.

I should look into reconditioning a battery.

Ha! Your speedo still has color! Mine is all yellowed out, from being in the sun. Believe it or not, but soon, the black will become brown, and the red will disappear (yellowed white). Heck even the white will yellow. The fuel gauge will bend down of the heat (I live in HOT S-Florida, and think the fuel gauge may actually have partially melted, being trapped behind a plastic window, the heat must have exceeded 200F in there with the sun shining on it)! If you care, it's better to treat the transparent plastic with a UV protective coating. I have a spray for leather, but never tried one for plastic. A BBK will help take off a LOT faster! You probably have a 63cc BBK installed already. I was thinking of putting a 72-75cc BBK in mine some day. But if performance matters, they sell 80-100cc BBK kits. All you need to do when buying the BBK, is rejet the carburetor ( for like $10 you got the right jets, or buy another carburetor that is jetted correctly, they cost like $20, or buy one with an airfilter, like this one: www.ebay.com/itm/Carburetor-with-Air-Filter-50CC-90CC-110CC-ATV-Go-Kart-Carb-Roketa-SUNL-Chinese-/281143973012?pt=LH_DefaultDomain_0&hash=item41757c9494No guarantee it'll work on the ATM50 though, but something similar). |

I've had a PT cruiser before, the manual geared ones have quite some torque!
Turn radius is very tight, but the tie rods go bad easily on those cars.
Need wheel alignments almost every 3-6 months!
If you take off the handlebars, I think a small 50cc would fit (the 80% sized scoots, like a TaoTao ATM50)
