Yep the cam thing I knew.
I think it's useful to look and engines' numbers and identify potential resctrictions that way also. Like with cams and compression. The dynamic compression ratio for example, is already pretty high on a 2008-12 250R at 9,6 if my calculator is right. In another motor I built, the number was 7,6 so that already told me where cheap ponies might be.
