Do you need a bigger throttle body an injectors with the 107 fuelmoto kit

 

No, you do not. I just finished mine over the weekend and I am running stock TB with stock injectors. I may swap out a little later on, but for now, they stay..

 

It all depends on how far you want to take it. If you go to the expense of head porting and oversized valves with a nice cam you're leaving juice on the table if you don't upsize. 51mm HPI TB 4.9 injectors would be a nice upgrade.
