TFC S-1 High Power Camshaft - GY6 Big Bore Builds 150cc as they are not includedMaximize the power potential of your GY6 big bore build with the TFC Special S 1 High Angle Camshaft. Designed specifically for engines running 58. 5mm to 63mm cylinder bores, the S 1 delivers 6mm of valve lift significantly more than a stock cam keeping the valves open longer and pushing them further to pull in more air and fuel on every stroke. The result is stronger mid range and top end power that a big bore cylinder alone can't fully unlock
