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

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. You have to be careful to set the gap on the rings correctly and to enlarge the main jet, otherwise you won't get the maximum out of it.
