{"product_id":"shin-yea-extreme-high-torque-gy6-starter-150-232cc","title":"Shin Yea Extreme High Torque GY6 Starter: 150-232cc","description":"Unrivaled Cranking Power: Shin Yea Extreme High Torque Starter Eliminate starting struggles on your high-performance build with the Shin Yea Extreme High Torque Starter Motor . Engineered specifically for modified GY6 engines ranging from 150cc up to 232cc, this is the most powerful starter available for the QMI\/QMJ platform. If you have installed a big-bore kit or high-compression head that your stock starter can't turn over, this professional-grade motor provides the massive rotational force needed for reliable firing. Technical Performance Features Extreme Displacement Optimized: Purpose-built to overcome the high cylinder pressures of 170cc, 180cc, 212cc, and 232cc stroker engines. Heavy-Duty Internal Windings: Features high-grade copper armatures and oversized brushes designed to handle increased current draw without overheating. Precision 9-Spline Shaft: CNC-machined 11.5mm splined shaft ensures perfect engagement with your starter clutch\/bendix, reducing wear on transmission components. Integrated Mounting Bracket: Includes a reinforced, GY6-specific mounting bracket for a secure, vibration-resistant fitment on 152QMI and 157QMJ engine cases. Mandatory Electrical Requirements WARNING: This is a high-performance component that requires significantly more amperage than a stock motor. To prevent irreparable damage and ensure warranty coverage, you must upgrade your electrical path: Battery: Minimum 9 Amp-Hour (9Ah) capacity required. Wiring: Upgrade to 6-gauge or 8-gauge starter and solenoid wires (Stock 12-gauge is insufficient). Grounding: Ensure a dedicated heavy-duty ground to the engine case. Technical Specifications Bolt Hole Spacing: 78mm Splined Shaft: 18mm Length \/ 11.5mm Diameter Nose Diameter: 30mm (at rubber seal) Spline Count: 9 Engine Fitment: GY6 125\/150cc (Short \u0026amp; Long Case) Mechanic's Note: This starter is a \"beast,\" but it is only as good as the juice you give it. If you try to run this on a stock 4Ah or 7Ah battery with thin factory wires, you will burn out the brushes or the solenoid. Pro Tip: When installing, check your Starter Bendix for chipped teeth; a high-torque motor will quickly chew up a worn bendix.
