Also I used the stock head, cam and exhaust. I also used a 150 carb. ### ⭐⭐⭐⭐⭐ Fantastic deal - bike runs great! *by O***N on February 8, 2026* Holy smokes this is a crazy deal. I was skeptical - real skeptical, but the kit was nicely packaged, came with everything and more (see my pics) NOTE: cylinder head and piston came vacuum sealed I just cracked it open to take a pic. Bike runs great. Install was super easy. Stock camshaft and head. Put it on my 49cc gy6 (abruzzi model) spent a few hours regretting my carb. I have a performance exhaust - cheap one from eBay.

Bought the jet kits from this company too. ### ⭐⭐⭐⭐⭐ Cheap kit worth quadruple of what you pay. *by C***N on March 1, 2021* Absolutely phenomenal product for the money. The quality in this kit is better than the original parts, (which for a Chinese scooter isn’t really saying much, but still) Extremely easy to install, it took me 30 minutes to disassemble my old engine parts and an hour and a half to install this kit and replace the main jet in my carb and get it running smoothly. (I am a highly experienced mechanic, but it would take someone with basic engine experience 3-4 hours total) Break it in the way you think is best. Just remember to warm it up before doing so every single time for at least the first 20 miles. It comes with more parts than you really even need, new studs, new nuts, new exhaust gasket, new umbrella seals for the valves. It’s really all there. This kit got my scooter from going about 35-40 to about 50-55, maybe more. Before, I could do about 30 on flat ground and 20 uphill, now I go about 40-45 on flat ground and 30-35 uphill. The biggest difference is the worst part of a 50cc scooter: immediate takeoff power. Before, it would have some trouble leaving a stop sign or in grass, now I have to be careful to not give it too much. Zero to 15 mph is a 250% increase in power, the rest is definitely better but nothing to exaggerate about. This kit will definitely make you feel glad you didn’t fork out the cash for a 110cc scooter, because it’s basically the same performance in a smaller package now. ## Frequently Bought Together - Glixal ATMT1-008 Performance Big Bore Cylinder Kit GY6 80cc 47mm for 139QMB ATV Scooter Moped Go Kart - Glixal ATGT-009B GY6 49cc 50cc to 80cc Engine 47mm Cylinder Head Assy with Valves for 139QMB 139QMA Chinese Scooter Engine Moped ATV Quad Go Kart (Non EGR Type, 69mm Valves) - Glixal ATKS-029 GY6 50cc 100cc High Performance A9 Camshaft 139QMB 139QMA Scooter Moped ATV --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/18691471-glixal-atmt1-008-gy6-80cc-47mm-high-performance-big-bore](https://www.desertcart.hr/products/18691471-glixal-atmt1-008-gy6-80cc-47mm-high-performance-big-bore) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-02*
