So I'm looking about for some new gearing for my mina engined scooty to add a little top end to it. here's the current (stock) gearing on my mina sofar (and was added to the tech library gearing database - thanks 90GTVert brent cuz i forgot what it was)
2006 TNG Venice 50cc 2T Minarelli
11.08:1 (Primary : 13/48 [3.69], Secondary : 12/36 [3.00])

First, I should ask about which set to swap. I know the primary and secondary work in tandem with each other, but is there any reason to suggest which set one should generally adjust? Like if the primary is too shallow and the secondary too deep, would it spin the press fit center gearshaft? Should the gearset stay roughly balanced for each other?
Secondly, i'm not looking to go any taller than 10:1. Ideally i'd prefer something closer to 10.4:1 but i know getting that specific is nearly impossible. 10:1 is possible though with the jasil 15-50 primary and my stock secondary, but that gearset is a smooth 100 bucks. Yes, quality, you get what you pay for, but i'd still like to shop around for some slightly more budget friendly gears before i decide to drop a franklin bill. Where does everyone else shop for gears? I've checked partsforscooters, scootertuning.ca, and a few german sites popped up. I'm excluding ali express and any chinese origin ebay sellers on this go, but i'd welcome some taiwanese gears if they're a good recommendation.
Any info you have to share on this would be awesome! Thanks!
