The bike is a YZ450F '05. Good racing 2day at Toddington, UK. 2 holeshots, 3 wins by my sponsored rider Robert Barney. I did the prep & checks between each moto. The forks have started leaking so we will replace the seals in the week. However, when I bled the air from the top of the forks the left one let oil out of the bleed screw. I have not seen this before. Any ideas why? Thanks.
