Just unbolt the pump, and block the holes where it’s lines mount to the cylinder. You can homebrew this by cutting the lines 1/2″ or so from the cylinder and crimping them up on themselves, screw self tapping screws covered with RTV silicone into them, or using a kit such as that offered by Applied Racing. See also my redundant answer below. #6 Q: What horsepower can I expect? (stock, uncorked, HRC) Because of the fact that all dynos read different, I’ll give you some rough figures. They’d be 40,50 (27% inc.), and 60hp (15% inc.) in that order. These are from Honda, taken at the CS, not rear wheel. Subtract 10 from each for what you are getting to the ground. The stock XR is kinda boring, but the uncorking turns it into a rip- snorting beast that will keep you in debt buying rear tires. The HRC kit will put you
