450 FSE motor replacement

[LeifNewman]

Hi, I am new to this forum and need some help. I have a Gasgas 450 FSE, year model 2004. The Engine has blown and I am looking for a replacement. I have found a motor from a 450 FSE, year model 2007. Will it fit right on to my bike?
Thanks for any advice or input.

I don't know, but the bikes tend to be pretty similar in major components
