Lost compression so decided to purchase same kit again, but after assembling, the piston hits the crankshaft and will not allow full revolutions. Piston is visibly different on the new kit vs. the old kit. ### ⭐⭐⭐⭐⭐ Good kit so far. Good compression after rebuild. Make sure you install rings the right way up! *by T***3 on September 4, 2019* When I first rebuilt my gy6 150cc motor I had low compression and excessive oil in the cylinder. I tore the engine apart again and found that my piston rings were installed upside down. I flipped them over the right way and the engine has 155psi compression and no oil problems. The motor runs great after 3 hours or so of run time. You DO NOT need to bore the case on your motor with this kit which as also really nice. You will almost certainly need to rejet your carb. I used a #125 main jet with this big bore kit, performance head, nibbi intake, and straight through exhaust. ## Frequently Bought Together - Glixal ATMT1-020 High Performance GY6 58.5mm 155cc Big Bore Rebuild Kit Cylinder Kit For 152QMI 157QMJ Engine Chinese Scooter Moped ATV - Glixal ATGT-021 GY6 125cc 150cc to 155cc 58.5mm Performance Cylinder Head Assy with Valves Set for 152QMI 157QMJ Chinese Scooter Moped ATV Go Kart Engine (None EGR Type) - Glixal GY6 125cc 150cc 160cc 180cc High Performance Racing Camshaft for 152QMI 157QMJ Based Engine Scooter Moped ATV Go-Kart (A9) --- ## 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.com.kw/products/24851736-glixal-atmt1-020-high-performance-gy6-58-5mm-155cc-big](https://www.desertcart.com.kw/products/24851736-glixal-atmt1-020-high-performance-gy6-58-5mm-155cc-big) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-15*
