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

Excellent value for money, I installed this kit today. I immediately felt a huge increase in acceleration! Very happy as it will help me move better in traffic. The whole thing took about 3.5 hours using only hand tools. I watched the Rolling Wrench Big Bore Install YouTube video which did a good job of showing what you need to do. All in all a great upgrade, if you're mechanically inclined you probably won't try it if you're uncomfortable with a wrench.

Great thing. I needed to replace the rings on my 2014 Taotao so I decided to update it while I was at it. There are some good videos on YouTube that will guide you through the installation process. If you take your time, it's very manageable. This kit doesn't include it, so I definitely recommend getting a new cylinder head if you have an old one. Mine was worn out and my valve seals failed 100 miles after installation. That's about $20 more, it's easier to just replace it while taking…

This kit installs very easily and improves performance significantly. I have a lot more bottom end power and when combined with a 20mm Keihin carb and a 90 main jet with the intake restrictions removed I can easily hit 45mph. I also run 5g reels to get more spin at low revs, I can climb hills much better. Where I was lucky enough to hit 20 mph, I'm now moving at 35 mph. People planning to just install this kit and run 50 should understand that they need to make the other changes I mentioned…

Great set of barrels. Not too difficult to install, but make sure you do your planning and research. There are some great installation videos on YouTube. Take your time and open the rings properly. Make sure the valve clearance is correct! You need to raise your main jet in your carburetor. Using a stock main jet will ruin your scooter engine. Regardless of how you plan to break in, change the oil after installation and after about 10 hours, and then again after 10 hours. Torque the cap screws…

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…
