Their hp may not fall the full 15%, but only means this is allowed.

By explaining that fuel injection adds hp to an engine from a performance standard, you will understand why the FX1000V engine I have on my 72" is listed at 35 hp, whereas when you move to the FX1000V-DFI you gain 2 hp, and now have the fuel injected model which Kawasaki lists at 37 hp.
I took the new HP numbers for each engine right from their sites puppy. The 29 Kohler is still not the equal of the FX850 even though it is fuel injected. The torque numbers are even farther apart.

I'll be glad when the day finally comes where they are all EFI/DFI.
