That's an interesting thought. I'd want to install this myself just to see how they match up. On my Kawasaki ZXi, I used Buckshot Carbs, which were actually bored-out Mikunis, then port matched them to the intake with a considerable amount of sanding (via flapper wheels + air compressor). A pipe wasn't available, so we smoothed out the aluminum casting. Every little bit counted and we were able to squeeze out an extra 25hp from that 2-stroke motor. Every little bit counted. In the end, each modification added little improvement, but collectively made a big difference in the outcome.
