I've seen these for other bikes but not for a Harley. Basically a syringe & rubber tube with a hollow screw that will screw into the drainplug that you can shoot the oil into the forks after loosening but not removing the endcaps.

Anybody have one of these?

 

Nobody seen one of these? Maybe it's time to think about making one....

 

You could always put a bleeder valve in there, and inject it with a hose and syringe then close it so you don't loose any fluid. There is a replacement-style bleeder valve that has the seat included. The seat is 1/8 NTP, so it would have to be drilled and tapped for that. See the 'HELP' section at the auto parts store.

 

So where is the air that's going to get displaced going to go?

 

+1 - You have to loosen/remove the fork cap nuts anyway to vent the pressure in order to both drain and refill the fluid.

 

I was hoping that loosening the caps would give enough breathe to the fork to take the oil. Thanks gpsjr10 for the size info, would the brake bleeder happen to be the same size? If not I have access to a drill press. I'm thinking that an allen head could be drilled down the center and the hose would slip over the head...

 

Seems if You have to deal with the fork cap nut anyway, it would be better to just get the a fork cap wrench to make removing and installing the fork cap easier and scratch free . cHarley listed the wrench in answer to a fork spring change I was doing. Worked wonders for Me.......WVleo

 

Why such an aversion to removing the Fork Spring Caps, its a piece of cake to do so.

 

I dont get it.
Most people never change the fork oil on a bike unless changing the weight, plus it only takes about 15 minutes to drain the oil and refill by removing the fork caps.
I remove the caps, then remove the drain screws, let the oil drain (no pumping of the forks) then refill.
If you want it real easy, and a better ride, the progressive springs make it easy to put the caps back on with just a regular socket.

I think it would be more trouble playing with pumps and hoses, the only thing that saves you is having to remove the caps all the way, which is no big deal.

If you think taking the caps off is an issue, Sporty owners have it easy. Many of the newer BT's don't even have drain screws. You have to remove the forks and turn them upside down to drain them.

BTW, fork oil should be changed every 20,000 miles or 2 years, which ever comes first.
