What happens if you have a bad fork seal?
A bad fork seal could leak oil onto your brake calipers, resulting in trouble decelerating and stopping the bike. That, plus poor shock absorption and an unbalanced ride makes a leaky fork seal dangerous to ride on.
Why are my fork seals leaking?
Leaks can happen after major impacts to the front forks, often times caused by large pot holes or wheelies. Dirt can become lodged in the fork wipers and seals creating a gap that oil seeps out of; this is very prevalent in off road riding. Another major issue is damage to the fork surface itself.
How do I know if my fork seals are bad?
Once both the forks are clean, take your bike out for a quick spin. If you notice oil or grime around the forks at the end of your ride, there’s a good chance that the fork seals need to be replaced. To prevent any further damage, you should get the seals replaced.
How do you remove oil from a Yamaha front fork?

Now the spring pressure will push the retainer plug out of the fork tube, so be careful. You can now remove the fork spring and, if you have not already done so, the oil.
