When I started with scooters & tuning I did asked myself a numerous of times “which exhaust is suited for my cylinder and what size of carb should I take; I don’t want to spend money on parts that don’t work well with my setup”.
Over the years I gained a lot of knowledge by reading and trail & error. To answer these questions I have come up with a list with different profiles for matching setups.
These profiles help you to check which cylinders and exhausts match and what size carburetor is suited for those combinations. For the parts mentioned in the different profiles I know that they work together.
Note that we are talking about stock (untuned) cylinders. Tuning a cylinder from profile 4, might upgrade it to profile 5 performance making it suitable for profile 5 exhausts/carburetors. This is just a guideline, so it's possible that other combination will work too.
