How do I change the fork oil on a 2002 Heritage Soft tail Harley?

How did you know the switch brake is good??

As far as the rear suspension, a softtail won't ride a smooth as one with a swingarm, as the softtail has less travel.

On the front end, Harley has three different "thicknesses" of fork oil, light, medium, and heavy, which gives different suspension dampening.

If the front forks are too stiff, you could try a lighter fork oil.

No. The axles, wheel bearings and fork lowers are different sizes.

I'm sorry but I don't have the specs on the quantity and type of fork oil for your year and model bike. I work on the older bikes that the dealers will no longer service. But, I can describe the difference between the "wet" and "dry" conditions of the fork assembly. If you take the front forks apart, clean them out, and put them back together with no oil in them, they are considered "dry". For a simple drain and refill type oil change on them where you don't get all the oil out of them, they are considered "wet". I hope this helps, You can call you local dealer's service department and they should tell you the quantity and viscosity of the oil that goes in the front forks on your machine. They'll tell you something like 6 ounces of "Type E" oil, for example. Harley-Davidson uses these types of specs to describe their oils. If you go to a website for fork oil, like PJ1, they may give a cross reference or equivalency chart for converting H-D "Type E" to their oil. I think that would be their 30 weight oil. If the front end seems too "stiff" with 30 weight, you can drop down to 20 weight. I think Honda makes a 25 weight but not sure. Your Harley won't mind the Honda oil. BG.

Good Luck

I long push on the remote turns it on, 2 quick clicks turn it off.
