According to the Boss Hoss Manual the forks need to have the oil changed every 2 Years on 24,000 miles. If you follow the instructions that some of us got with our manual it will be a real bear to do. I did that because I needed to change the springs, because mine had gotten weak allowing the top forks to hit the brackets that hold the fender. It was serious because it pushed the fender down causing the tire to rub a hole in the top of the fender.

To change the fork oil it is rather easy by loosing up the top pinch bolts on the top tree then remove the top caps. Then you remove the front tire, fender, top windshield brackets and loosen the other two pinch bolts on each side of the lower tree.
At this point the fork will slide out of though the bottom allowing you to turn the fork upside down and drain the fluid out.

Don't take the fork apart unless you have leaking seal or need to replace the springs.

(To take the springs out you need a special tool and lots of help. I built one and if you want to borrow it I will send it to you. It is home made but works like a champ.)

The seals are made by Honda and have a cost of $15.99 each side.
Part number is 51490-MWO-003. Any Questions on this send me an e-mail or call at 209-869-1672

Adrian - doesn't the new style front ends have these little two oil drain grub screws at the bottom of the tubes - like the old style forks have?? :shock:

No, they sure don't, plus they hold almost a full quart of 10W fork oil. The springs don't come out like the early style and are a real bear to do.
