I have 996 forks on my 900SS CR. I'm going to put in new fork springs, 0.9 to replace the 1.0's in there (200 lb rider weight). What weight fork oil should I use and what level should the oil be measured at? Racetech recommends their 2.5/5w but I don't feel like paying $50 for fork oil. The fork internals are stock -- can't afford the Gold valve kit just yet.
