The differance in the 2 systems mean little in your case but many on here have suggested mods to the d-jet that work and it appears they do, your system however is differant in the respect you have next to no tuning mods for it,the 96mm kit is a straight fit in job no mods to do ,if you want to you can split the case and go to a higher lift cam but YOUR system limits that and I don't really know of a cam for these ,maybe they are out there as cabinetmaker has suggested.....Google and then Google again,have never looked myself.
If you are changing to 96mm barrels and pistons it's pointless not to tidy up the heads,a good recon job on those will work with the bigger bore and way cheaper than splitting the case for a cam which will be limited by your injection.
A stock head can be given a good going over and realize 15% more flow without huge expense,new tapered exhaust guides and valves and you can go to 40mm inlet valves without changing seats when cut to suit.
My take on the K-jet is to get more air in and more exhaust out you need to have the throttle body bored ,heads ported or cleaned up with a better than average valve job and a good exhaust header,but thats expensive but I have no idea of your project cost outlay.
