Horsepower question RM250

[250girl]

I am sure this question has been beaten around repeatedly and I will probably get deleted, but I'll try anyways. I have a 2000 RM250 with an fmf pipe on it and who-knows-what -else. All I want to know is how much (roughly) HP my bike is putting out. I've been told by many different people, and nobody seems to have the same answer. The number usually falls between 40 and 58 hp. Just wondering if anyone around here knows the stock hp of this bike.
Thanks in advance
