    If your goal is to increase the top speed (who would of thought) or displacement, then you legally can ONLY if you register it as a motorcycle. If you are not old enough to register and be licensed to drive a motorcycle, then you will have to stick it out.

    You can change any part you want as long as it doesn't affect 1) emissions 2) the cc's 3) the top speed. 4) any lighting required by law.

    Now the question is, why would you bother?

    You don't get inspections. You can legally do whatever you want as long as the bike's top speed does not increase over 30mph and you don't increase displacement. And you don't find new laws to break, like noise ordinances.

    I have this little 50cc scooter. It's slow. I want to make it faster.

    Guess what, it is slow for a couple of reasons. Most local laws that qualify this as a moped require that a 50cc scooter go less than 30 MPH (48 KM/h) on a level surface. They are also usually limited to 3 horsepower or less by law. Most modifications that would make this scooter any faster than it is will also make it illegal.

    If you soup the crap out of this motor there is very limited potential in this tiny motor. If you were to increase the power an unrealistic 100%, that's only a measly 6 HP.

    You have 3 choices here.

    Choice 1:

    Keep it as it is and be satisfied with what you have.

    Choice 2:

    Throw lots of money at it in parts and labor only to realize minor improvements in performance. Then discover that you have now made your scooter unreliable because you are putting too much power to the rest of the drive line components and things are starting to break. So now, you need to throw even more money at it in repairs. You will also discover that you will very quickly run out of gearing. You can only rev this tiny motor so fast, no matter what you do to it. In addition, the transmission design of most scooters makes them difficult to change the final gearing. Therefore, what you end up with is a scooter that will accelerate better and slows less going up hill. However when pushed too hard on level ground your risk catastrophic engine failure. Spinning a little engine that is designed to max out at 7000 RPM to over 9000 RPM and you are asking for trouble. Your little souped up scooter quickly ends up a worthless pile of junk.

    The small tires found on most scooters and mopeds are not safe above 35 to 40 MPH (55 to 65 KM/h). Have you ever heard of "Death Wobble"? It's not pretty.

    Choice 3:

    Enroll in an accredited Motorcycle Safety course and start working at getting your motorcycle license. Sell this tiny 50cc scooter. Take the money from the sale. Add the large amount of money that you would have spent on upgrades and repairs. Put it towards something with a larger engine. Maybe a 125 or better yet a 250. If you are restricted to 50cc or a certain horsepower, this may not be an option. You will need to wait until you are old enough for a motorcycle.

    A 125cc or 250cc motorcycle will be much faster than your tiny 50cc scooter could ever hope to be. And since the drive line components of this larger bike will be matched to the power of the larger engine from the factory, it will be a much more reliable ride.
