SSP-G Boring Tool (QMB, QMF, GY6)

Description: A must for using most large bore cylinder kits beyond factory, especially installing a GY6 cylinder kit larger than 61mm requires the factory crankcase to be machined. That is why we offer SSP-G Engine Case Boring Tool which allows a bore-cut to fit cylinder size 61mm for 171cc, 63mm for 180cc or even whopping 63mm for 205cc with extended stroker displacement on a 54mm stud GY6 engine (crankcase). Will also work on 139QMB crankcase bore up to 52.4mm.

Note: The supplied hardware is for GY6 engines utilizing an M8x1.25-cylinder stud. Other engine applications will require different hardware not included with this kit. The cutting bit and adjustment allen bolt may need to be shortened to work with smaller displacement engines.
