How to make my 50cc bike go faster

[damudut400]

So my Yamaha Zuma 2004 stock bike only goes around 38 MPH. I am a complete new by, I want some mods to make it go at least 42 MPH but don't want to spend much. Help me.

Tune the variator with a decent kit and make sure to buy multiple weight rollers to start.... then start looking to really spend money and time on it as your addiction grows. But seriously disl in the variator with a decent variator kit. Also, when upgrading do one mod at a time so if you have an issue after each you will know what the culprit is instead of doing a grocery list over a long weekend and then not knowing where to start if something is afoul.
