2002 Vulcan Classic 1500 Fi engine swap
 

I am wanting to swap a 2002 Vulcan Classic 1500 Fi engine with a 2004 Vulcan Vn1500E non Fi engine.
Is it possible to do and if yes can I use the Fi parts from the 2002 engine and use them on the 2004?
What I am asking is can I make the 2004 into a Fi with the parts I have from the 2002?

Thanks
