You've got an almost perfect side shot there, and there are shots of stock bikes from the same side from the same angle. You could copy a shot of a stock bike match the sizes to each other using the engine dimensions, and then you would be able to see the differences and figure out what was moved and how much by measuring and calculating. That would get you way closer than a stranger's guess from the internet. It's really not that hard to figure out, but I'm not interested enough in the answer to do the work.
