Good parts cost money, not a lot of money but spend the extra 20-30 on a good carb or you’ll be running in circles.
Don’t be mismatch swapping parts if you don’t wanna change everything you want at once, I’ve found that you spend the least time with a headache and more time riding if you swap the kit, carb, pipe and CDI if you go that route all at the same time. That way you can tune everything to a fresh top end, time it, jet it, gear it and get on the road.
No silly clone parts unless you’re just gonna steal small parts off of them.
The amount of time and labor you’re gonna spend cutting, drilling, shaping, powder coating an intake (plus the cost of materials and tools) Personally id just look for a used one if you’re not in a rush, if I am it’s worth the extra 20$ to be able to get the project back on the road.
There’s always someone who can find something cheaper, but it’s not always worth the time... especially if you wanna just enjoy a good moped ride.
