Are they RM250 USD forks? What year? If so, I am mocking up a set of twin chamber 47mm Showas up as we speak. The overwhelming thought (from the small group of people who have done this) is that the MX forks are too harsh and require a revalve because you don't use enough of the travel. Mine will require a 1 1/2" deduction to balance the bike front to rear also.
I say mock them up and ride them. If they are in fact too harsh, send them out to be revalved. You will get the complete set-up, have any parts needed to be replaced, and fresh fluid.
