Has any one tried 0w-30 grade oil in the forks, my A65 has had new fork legs bushes and seals, still on the same springs, i currently have 20w50 castrol in them as was advised it would stop the problem, they do not bottom out all the time just the odd ocassion, maybe the springs have seen better days and need replacing. ive ordered some 0w-30 to try first, but in the back of my mind i think the springs could be the problem. any advise always wecome, except lose some weight you fat bar steward lol.
