Review on 🚀 Glixal ATMT1-008 Performance Big Bore Cylinder Kit GY6 80cc 47mm: Boost Your 139QMB ATV Scooter Moped Go Kart! by Allan Ryser

Absolutely phenomenal product for the money. The quality in this kit is better than the original parts (which doesn't say much for a Chinese scooter but still does) Extremely easy to install, it took me 30 minutes to disassemble my old engine parts and an hour and a half. Install this kit and replace the main jet in my carburetor to keep it running smoothly. (I'm a very experienced mechanic, but this only takes 3-4 hours for someone with basic engine experience.) Break it up in any way you see fit. Just make sure you warm it up for at least the first 20 miles before doing this every time. It comes with more parts than you really need, new studs, new nuts, new exhaust gasket, new valve umbrella gaskets. That's really all. With this kit my scooter accelerates from 35-40 to 50-55 and maybe more. I used to be able to do about 30 on the flat and 20 uphill, now I do about 40-45 on the flat and 30-35 uphill. The biggest difference is the worst part of the 50cc scooter: instant starting power. He used to have trouble walking off a stop sign or in the grass, now I have to be careful not to give him too much. Zero to 15 mph means a 250% increase in performance, the rest is definitely better, but nothing to overdo. This kit will definitely make you glad you didn't go for a 110cc scooter as it's now basically the same specs in a smaller package.
