I have considered raising the compression ratio of my 2012 Ninja 250, but the stock compression ratio is already fairly high at 11.6:1. For street use I question if the minor performance gain is worth the reliability hit - the engine will definitely run hotter.

Instead I have been looking at installing drop-in performance cams. Daniel Crower Racing and Web Racing makes these. Should provide about 10% more peak horsepower over stock, and should complement the Yoshimura full system exhaust nicely
