o4 and o7 engine
As far as I know, the engine itself is the same. Why are you thinking about changing it out? you might just as well spend the money on a stage2/3 upgrade to your existing motor and get 90-100 hp out of it then.
I thought it was weird too, But would they call it "From EFI to Carb downgrade"
Depending on the components and the tune a lot of carb bikes are very similiar to EFI bikes on most of the Dyno reports I seen.

reason for the engine switch is. something went in the bottom end of my engine and now it knock loud like sob. was qouted by to 2 diff shops it would be around $3000 to replace and won't start on it till winter.

just my opinion you would be better off watching ebay and finding a used motor. im not completely sure but i think i read on a different forum that the heads are different and a few other things too.
