Very intersting read. I have a 06 kawasaki zx10r and I have some experience with cam timing, different static compression, and different cam profiles, but have very little data for mpg, since I drag race the bike mainly.
My bike started its life with 12.7 static compression, 300 duration with 9.1mm lift intake cam and 292 duration 8.5mm lift exhaust cam and 17/40 gear ratio. It ran pretty good stock and I was getting around 30mpg or so. Intake valve was closing at 74deg abdc. I then redid my fuel map and the bike was getting 43mpg. My next step I put a 9.7mm lift and 296 duration intake cam and raised my static compression ratio to 14to1 and my intake cam was set to close intake valve at around 80deg abdc. The bike still ran on pump gas but peak hp went up past rev limit of 12.5k rpm so I had to advance the camshaft 5 degrees so it would peak before rev limiter and improve power #'s everywhere else which it did. I haven't gotten much data for mpg though due to my gear ration that 15/40 right now. Here is the dyno #'s between 12.7 comp and 74 deg intake closing time and 14 comp and 80deg intake closing time.
