You know, Jeremy is the one that knows all that stuff, You should click on his add above for Enviromto and look at his stage 4 upgrade. I'd go with what is in that kit if I were working on a fiddy. www.enviromoto.ecrater.com/product.php?pid=3956702Otherwise you can go to ebay and search their offerings, another member here, pedez, has an internet store and sells many of the same parts as Jeremy.

Thanks for the nod Rebel.
The stock jet is usually a 85 but I have seen as low as 78
Yes the 150 and 50 CDIs are usually compatible
19mm is the stock carb size I do believe.

Yeah, and you're gonna NEED qmb jets....they got a tiny, oddball body size....I had NOTHING to fit, and wanted a couple of spares before I started drilling. My(ross's) original, UNMARKED main, ended up being a 78....more emissions down sizing, I guess. the 80 I got from Jeremy, paired with a 38 pilot is working great, for a near box stock configuration. But I can see an 88 easily with the 72cc kit, posssibly a 90, since we're going big valves and cam, possibly a smaller version of my IR pipe....
But listen to Jeremy, he's pretty well got those plug and play 72cc kits sorted, and can put you on something quick, I'm sure.

Where are you getting your speeds? the OEM speedometer, or a GPS unit, vapor unit? ...just curious. Show us some pics! Also, don't forget, SVERRAL manufacturers have, for whatever reason, slid some 65cc scooters under the Radar, branded as 50cc, to include 50cc paper work..... they will run like a scalded Dawg! Have personally seen 2 examples, and the only way to know for sure is to pull the head. The cams in both also degreed out as 4* advanced, over ant other stock 50cc cams I've seem. You may just have a "sleeper" yourself. A few of those in every 100 on the street, sure help sales! So rather than bash what everyone else has, maybe you should just be grateful for what YOU have. ;D

well they are what they are.
You buy what you can afford sometimes and you learn about other options and explore improving what you bought. It really does not take that much to get these to the 45 mph. For a $500.00 scooter that might go 35 - 40, you add a big bore kit, jets, open the exhaust a little, and a uni filter. You will have added about another $150.00 to its cost. and be pushing it to 45 - 50 mph
