Size: 62.5mm Big Bore Cylinder
This is a stock cylinder for a 1P63QML so three stars just cause they are kinda hard to find. This IS NOT a big bore kit of any sort and is a stock 62.5mm cylinder for a very specific 177cc gy6. It IS NOT a gy6 B or B-block cylinder and is not a gy6b/ B-block 57x57mm stud spacing' its 55mmx60mm spacing. It IS NOT 170cc or 180cc or 200cc. ... show more

We rebuild 110cc atv engines all the time and this is a great price for a complete head and gasket set. We found nothing wrong with this head set. This set came with all the gaskets you will need to assemble your 110cc engine.
