300EX Big Bore Kit
+2mm big bore kit, includes JE Pistons complete piston kit and a
Cometic top-end gasket kit. This kit is a nice ‘wake-up’ call for
your 300EX, and still gives you another bore in the stock cylinder
later. This kit requires your stock cylinder to be bored and honed –
if you’d like us to do that work, just contact us.
