I have a quick question guys :) (i'm also new)

So, hi everyone! i'm new and i have a few questions i have a 2003 Quijang (sp?) 50cc two stroke scooter. I'm not sure if the oil mixer is working so i'm just mixing the oil myself, recently i've replaced the coil and spark plug and put in a new battery and she runs great! tops out at 30mph though, which is good. However i'm trying to figure out a few preferably cheap performance upgrades to maybe get up to 35-40mph, because my current vehicle (Jeep 4x4 ) is going to be put up on blocks for some welding. So i was curious what you guys could recommend to me Thank you,

Kit.
