Here's dyno-chart of 300 with tuning via PC. Yours won't be exactly the same. You can use it as a rough guideline. Kawasaki tuned 300 same as 250R with way too much fuel in high-end. Leaning it out to max-power producing AFR of 13.5:1 gained +4bhp , +15% more power!



An engine making max-power is gonna be rough and raw. It'll be almost temperamental and needs slapping into line. But it'll be FAST! Remember that '60s hot-rod saying...
