Go for it.

if i were to chime in, go for a 2v 1000ss ie motor, 12mm engine bolt, sleeve them. can fit the throttle body's, will have to shave off tabs, higher end, better cams, easier build. I have already stuffed and 01900ssie motoer into a 96 carby frame, not a big task, just need a motor, wire harness from m900ie (not an easy find) and an ie tank ( not an easy find)

I am planning to change my engine in my 2000 M900Sie to a 998 Testaretta
Does anyone know of some ware that I can find some information about this type of operation? 

There is a bike for sale here in Aus which has this mod (or similar). Search bike sales.com.au under S4RS and it comes up. You might be able to reach out to the owner and ask for advice.
