front Fork too stiff need advice
Hello guys , I had problem of leaking oil from front Left Fork of susspesion. I Have L2 GSXR 1000. I Removed both forks of course and Change the Oil and Seals on both of them, I used 43x54x11 seal + Agip 5w with 22 viscosity at 40C. Seal was not OEM but Size was same , My Forks OEM oil is Showa SS-05 with 15,7 viscos at 40c but now I am using Agip 5w 22visco. and now about problem
I installed Forks on motorcycle and started to adjust the forks like it was said on manual, I did everything correctly adjustment but forks was very very Stiff , then I setup everyiting ( spring pre load , damping force and compression damping ) to the softest possicion, I mean all parametres was setup to the softest, forks looks better now but its a bit more stiff then it was 1 month ago with Manual Setup .
could you guys tell me whats the reason of that ? is it possible that guys in shop who did the changing of oil and seal did something wrong on install of forks ? or is it possible that I installd fors on motorcycle wrongly ? or what is your advice what I have to check ?
thanks for reading my problem and wasting time on it
