It is common for a ground wire to come loose so I would first check the wiring . Has it been going out but still run or die all of the sudden ? Got a spare CDI to test ? On my 2T the crappy boot kept coming off and the spring broke off . I had been unscrewing the cap off off the sparkplug tip but after the spring broke I had to put in back on and jam the boot on . I bought an orange coil and wire combo from Scrappy Dog and it was new again . It would run but fizzle . No fire could be CDI , coil , crank trigger , bad run/kill switch etc so you will need to run a continuity test and see where the flow stops at .
I would do the starting or carb cleaner spray test after I tested for fire and it was good .
My tank busted so I premix and had the oil light buzzer wire drive me bonkers . I heard some have an ignition kill if the oil gets too low to prevent burning it up , so I had mine running when I cut it in case I would need to splice it back together .
Simply always top off the oil every time you get gas to know its good .
It is worth the extra to get a full synthetic or at least synthetic blend of 2T oil like Maxxima or Motul 710 . Just make sure it says oil injector approved as some is premix only .

How are the RPMs at top speed ? My TaoTao came with 8g rollers and I went down to 5g and it went faster . I blew up the " secret 63 " and put on an Air Sal 50mm BBK and yowsers it was much better with a main jet . Did you remove the restrictor washer in the variator ? Could be geared too low . My 63 it would say 55 on the speedo but it was not accurate . A buddy had the same setup and I clocked him on my Echarm and it topped at 45 mph even though it showed 55+ on his speedo .
If you are going to make it a lil hot rod I suggest getting premium tires in order to be safe and ride good as they often come with tires under par . I got some killer Michelin tires here tires

You can go up to a 47.6mm BBK with out boring the case . You can get a complete kit like this power kit A BBK , larger carb and a pipe with expansion chamber can do wonders . Some use a 10mm wristpin others a 12mm so measure before buying . I like how your bike can use wide tires instead of the 10x3.5 like many small scoots use

I went to Bike Bandit as they have premium tires for the same price of a generic one in town and free shipping with orders over 100 . I showed my dealer my tires and he noticed the sticker as he buys from the same wholesaler as BB does . I paid cheaper retail price than he gets from a whole seller so he is now a BB customer too .

I had my tire go flat once from sitting up . I just bought new tires and stems and darn it it already went down twice . I push on the stem and it leaks darn it . The stock tire it would not roll, however my Michelins seem to be run flats . I got on it and noticed something was wrong ( it had no sag in the tire at all ) and I pulled over . I thought a shock broke or the frame cracked . I went home and everything looked fine and I kicked the tire and noticed it was not hard like it should be . When I put air in it I noticed the slightest touch the stem would leak . So I will be getting another stem in the morning .
I have used Goop ( like Fix a Flat in off road motorcycles but never tried on a scooter .
You can use soapy water or baby powder to help find leaks . If you want to dunk the tire make sure not to submerge the hub and get water in the bearings .
Once you fix the leak and if you can find a shop with nitrogen fill the tires with it instead of air and you will have less leakage

Aprilia is a great brand but expensive . The SR 50 has EFI and would need the ECU remapped to really be a screamer .
CFMoto is another great brand but they quit making scooters except a 250cc as they now have motorcycles in their line up .
I have had Hondas and so far they have all loved me and are far better than the China scoots . Even their 50s are pricey and their 150s are waaaaay over priced . Avoid the Metropolitan as it is slow not really and aftermarket selection of parts . A used Spree or Elite with a 2T engine would be good .
Yamaha I love the Zuma with its fat tires and 2T engine . My dealer has a custom one that is a wheelie machine .
I have a Jonway Magnum which its parent company is Sheike ( something like that ) and it is quite good but I have read where others were not as lucky as me . Note mine is a 2T not a 4T like most .
Avoid TaoTao as I had an ATMa 50 and man what a . I was used to 2ts and I hated it . Rode bad , headlight was barely a candle , cracked the piston on day 2 and blew up it 6 weeks later . I had to put an aftermarket piston kit since I had two go sour . I have had 30 or so two wheelers and NEVER once had a piston problem .

NCY is a good brand . Alley thanks for the tip that their springs may only fit their clutches . I have Hoca springs in my stock clutch .
Dr Pulley makes great products as I love their sliders way more than standard rollers . I have read both good and bad on DrP variators . Now their clutches cost 2 to 3 times as much as most but include a few spring sets and weights in order to fine tune it . Greg sells them cheaper than other places and you may have to look around their to find the exact one for your needs here DrP Hit
I am looking into getting a Stage 6 clutch since it has a lighter bell and I can change out the clutch springs without removing the bell unlike most .
Here is a video of a 4T and a 2T CVT operation . Note the differences in the belt travel
