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 & 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.
