Yamaha Raptor 700 815cc 770cc 108mm Big Bore Cylinder CP Piston Kit Top End Kit
- Don't be fooled by other sellers claiming that the 106.5mm Athena Big Bore Cylinder Kit is THE BIGGEST BIG BORE KIT ON THE MARKET, it's not.

- WORKS WITH STOCK OR BIG VALVES & CAMS (Recommended though to get the most power out of the kit)
- WORKS WITH STOCK OR OEM CRANKSHAFT, NO CONNECTING ROD UPGRADE REQUIRED! (Recommend new Hot Rods 4178 Stroker Crankshaft to hit 815cc!!)
- Requires Heavy Duty Aftermarket Stud Kit, which is INCLUDED.
