So I have torn down my rear shock on my 01 cr250 "leaking seal head" and I was wondering if anyone could tell me what fluid they recommend and how much I should be ordering? I was thinking about the racetech ultra slick 5w, would this be good oil to use in the shock and forks? Also I am thinking about respringing the shock and possibly the forks. Racetech shows for my combo a .44 front and 5.499 or closest rear. Mx tech shows a 5.0. After doing a lot of looking I'm am not sure what would be the right step. I know that the fronts factory were .44 or at least what they were supposed to be. 195 pounds without gear novice to intermediate doing harescrambles and trail riding. Would I be alright with just installing the different rear shock spring for now? Beings that the suspension has been completely untouched "not even a service" since new im thinking anything will be better then what is there now.
