i must disagree, although having the correct spring weight is of utmost importance,the two should go hand in hand especially on the 98 rm 250! when i had my 98 revalved it took on a whole new personality,it went from a so so ride to my alltime favorite bike, huge difference!!! no more fighting the bike, just sweet smooth compliant suspension, totally increases the fun factor and thats what its all about!! go for it , you will never regret it.
