Nope you dont need to take the forks off to put the new oil in thats even more of a faf (if its a real word) , we loosened the top yoke and pushed the forks down enough to pour the oil down the top. Obviously we drained the oil.
And btw we just added another 20ccs of oil still going to bottom out when i go over stuff becuase when i bounce around on them they go down as much as they did before.
