Ok I am going to revalve my suspension on my 04 YZ 250F. I was doing some spring rate search over at race tech's website and the reccommended spring rate for the forks is a .435 and the stock spring rate is .430. Is that close enough to where I wont notice a difference? On the shock they reccomended a spring rate of 4.92 and the stock rate is 4.7. Now I noticed a little bottoming from the stock shock but I went a half turn on the high speed compression(I think) and it seemed to fix it. Will I notice a huge difference going with stiffer spring? Or will I be ok with the stock spring? I planned on just buying the gold valves(type 1), but was thinking, would replacing the seals and bushings make a noticible differance also? Also in case you were wondering I am about 170 lbs with gear off but I entered 175 lbs just in case I have a big meal before I ride or something. So thats how all the spring rates were measured.
