GY6 125/150cc Case Boring Tool for Engine Builds
This GY6 Case Boring Tool is made for riders who want to step up their GY6 engines. It lets you machine engine cases accurately when fitting a larger cylinder kit. It is one of the GY6 150cc scooter parts builders often need for big-bore work, and it helps ensure a correct fit in performance builds.
Machine Your Own Case
With this tool, you can skip the expense of a machine shop. It helps you bore engine cases precisely and consistently so larger cylinder skirts seat properly. The adjustable cutting diameter covers 170cc, 180cc, and bigger conversions on GY6 125cc and 150cc blocks.
Pilot-Guided Alignment
The pilot design keeps the bore centered on the crankshaft axis, which helps prevent misalignment and lowers the chance of engine damage. The hardened steel cutter works through cast aluminum cases and produces less heat while it runs.
