Building a GY6 50cc motor on a budget with budget mods l Part 4

This is a spare BUDGET GY6 motor I’m experimenting for my scooter Mr frank from various parts I have laying around, I decided to port and polish intake & exhaust ports as a future mod when I do get a bigger Carb and exhaust.
This setup will consist of a 80cc barrel and piston with 50cc ported head.
