2006 kx250f vs 2007 kx250f Motor question

I need help, I am rebuilding my 07 kx250f and need engine cases and my question is are the engine cases off an 06 any different or even off an 05 any different. I know it is a different frame, but was thinking that they were the same motor? Any help would be great. Thanks.

since the frames are different I bet the motor mounts are different but I'm not positive.

I believe the cases are the same from 04 to 08. They had some internal changes from year to year but a 05 motor will bolt into a 08 and vice versa.

There were minor changes each year, but all engines fit from -04 to -08.

The -08 got reinforcments in the cases round the crank as only difference, don´t know exactly how much it affects. Doesn´t matter though, as cases are replaced in sets...

      2015 Kawasaki KX250f - 20 hours
      As close to new as I'd imagine you'd get! I bought the bike brand new, I'm older and have taken extremely good care of this bike. Very little use and is COMPLETELY stock - everything is original. 
      Comes with the title, original book and map couplers for the fuel injection.
      $4700 - cash

      Time for a top end on my bike, just wondering if there are any alternative Valve springs i can use. I have PC cams and $400 for just the springs and retainers is alil costly at the moment.
      This has been fun in other sections of TT, so I'll start the thread here and see if we can keep it going.
      Let us know what kind of mods, fixes, changes, etc.., you performed today, or just general fun you had with, your KX250F.
      I'll start with.. I installed a correct for my weight Race Tech shock spring, along with a Pivot Works shock spring thrust bearing. Also cleaned out all the nasty yellow plastic/wax crap that passes for grease in the lower shock bearing, and re-lubed it with Bel Ray waterproof.
