High-Performance Valve Spring Kit for Genuine Buddy and GY6 Engines
This valve spring kit suits Genuine Buddy scooters from 125cc up to 170cc, along with a range of GY6 engines that use 2-valve cylinder heads. Compared with stock springs, it helps the valves hold their action at higher RPM. It is one of the GY6 150cc scooter parts that can noticeably sharpen throttle response by cutting down on valve float. Every valve gets one inner spring and one outer spring.
Build and Materials
The springs are manufactured from electroplated steel for added strength and wear resistance. The inner spring has a 12.25mm inner diameter and is 32.5mm long, while the outer spring has a 17.20mm inner diameter and is 35.6mm long. Wire thickness is 1.96mm for the inner spring and 2.9mm for the outer spring, which gives solid support during high-RPM running.
Compatibility and Fitment
This set works with GY6 QMJ157, QMI152, QMK161, and several other engine codes. It is designed for a broad range of 2-valve cylinder heads, so it covers many different scooters. For any scooter running a GY6 engine, it is a dependable choice for better performance.
