I'm all the way in on both my rebound and compression on my shock and the rear still is to soft. The thing is that the bike is now 2 years old and I haven't had the shock oil changed yet, if I have this done, will this help or do I need a revalve? Also, I put a stiffer spring in then stock, so I'm thinking that I might need a revalve to compensate for the stiffer spring.
