420cc Ported Head & Free Compression bump = Massive Gains!
No fancy tools, no machine shop, just pure garage grind. I ported the head, shaved it down, and bumped the compression to squeeze every ounce of power out of this beast. The result? Massive speed gains and throttle response that’ll make your jaw drop.
