SOURCE: 2007 HD Sportster 1200C - front right fork leaking fluid

The headline of your post seems to have it correct, you have a fork seal leaking. To replace the seal, you must remove the fork slider, the lower part of the fork tube to replace the seal and then refill the fork with the proper amount of the proper oil. Here's how you do it on a conventional front fork. This is not for an "inverted fork" where the top part is larger than the bottom.

Remove the front wheel, the caliper if it's on this side or you decide to do both sides. Loosen the pinch bolt on the back side of the lower triple tree. Remove the large nut on the top side of the upper triple tree. Caution: there is a large spring under the nut. Usually, if the bike is completely off the ground, the sping is almost fully extended but it will still have some pressure on it. Remove the spring and work the fork tube out of the triple trees. Turn the thing upside down and pour the oil out of it. Notice in the very bottom of the lower slider where the axle goes through, there is an 8mm hex head bolt. Using a brand new hex key, remove this bolt. A hex key socket on an air wrench helps to remove this bolt. It takes a "piloted key" but you can get it out with a regular one as long as it new and not rounded. Once the bolt is out, pull the top tube out of the lower tube. You'll see the oil seal in the top of the lower slider. Pull the seal out and replace it with a new one. Reassemble the entire assembly and install back into the triple trees. Add the proper amount of the proper weight oil. This is what is commonly called a "dry" fill since you took everything off and wiped it down. Then insert the spring tapered end first and put the large nut back on the top.

Then do the other side if you wish. Only do one side at the time. The remaining tube that is put together helps hold the tube you're working on extended.

Good Luck
Steve

That depends on where it's leaking. If it's leaking down at the axle, You can lift the bike off the ground, remove the front wheel. There's a bolt in the very bottom of the tube. Take the bolt out and slide the "slider" off the upper tube. While you have it off, replace the seal at the top of the "slider". This will fix any leak at the top of the slider. Clean the lower slider with clean mineral spirits and allow it to dry. Then, put a little bit of oil on the seal and a dab of clear RTV in the area where the copper washer goes and slide the slider back up on the tube. Put the bolt in and tighten it up. Replace the front wheel. Now, add the appropiate amount of fork oil for a "dry" refill. If you call the dealer, they should tell you how much oil goes in there. My manuals are not up to date for your model. Mine only shows for 1994 and Harley may have changed the fork tubes since then. Remember the higher viscosity of the oil, the stiffer the front suspension. The dealer will also tell you what oil came in the front forks from the factory.

Good Luck
Steve

How do i change fork oil an will it make them stiffer an is they a number where i can talk to ya


To change the fork oil, look down on the lower part of each fork leg just above the axle on the backside of each leg and you'll find an Allen plug or small screw. Take this screw out, hold the front brake and push down on the front forks. The fork oil will come out of the tube. Do both sides at the same time. Once you get the oil out of them, reinstall the drain plug. Then, take the large hex cap on ONE TUBE AT THE TIME and pour the correct amount of the correct fork oil into each tube. There is a specific amount of oil that must be poured into each leg. Since you simply drained your forks instead of disassembling them, you should use what is known as the "Wet" quantity of oil. I'm pretty sure your bike takes 9.0 ounces of oil in each leg. Call your local dealer and they'll tell you how much oil to put in. Your bike came from the factory with "Type E" oil in the forks. The viscosity of the oil determines the dampening effect of the forks. Heavier oil will stiffen the front forks, a lighter viscosity of oil will make the front end softer. You can check the Internet for fork oils and they should give you a comparison of what weight oil is equivalent to "Type E" oil. I think PJ 1's 30 weight oil is the same as type E Harley oil. Use only "fork oil" in your front forks as it has special "anti-foaming" agents in it. If the oil foams up, you'll lose the dampening effect in your forks.

Good Luck

Can i stiffen up the tension in my front forks on my mgx dxr?


Sorry to inform you, but there is no adjustments available for the forks that come with your bike. Adjustable forks (just the fork) start in around $250-.

On the positive side since there is not adjustment capability the fork does not need regular servicing like the adjustable forks.

I just bought chrome fork sliders how do i remove the old ones?


If you remove the front wheel, front brake caliper, and front fender and look on the very bottom of the slider where the axle came out, you'll see an 8mm socket head bolt. If you remove this bolt, the slider will come off.

But before you do that, I'd advise draining the oil from the fork leg and releasing the spring tension on the slider by removing the fork tube plug and removing the spring. To get to this plug, you'll probably have to remove the windshield, the nachelle, and the top cap. Then loosen the clamp bolt in the lower triple tree and allow the fork to slide down and out of the triple trees.

When you refill the fork with oil. Use the same amount and viscosity as what was in there. Thicker viscosity and more oil has a tendency to "stiffen" the fork.

Good Luck

Soft front suspension how can i stiffen the front suspension


If it has air caps on the top of the forks, you can put a little air in them. If not, the other thing you can do is add a bit more oil to each fork leg.

94 shadow vt1100 front forks to soft.


Does it have a bad fork seal? Check this by popping the dust cover off the lower legs and if you see fork oil on top of the seal than it has gone dad and needs replaced. Adding oil to the forks will stiffen then back up but if you have bad seals then you will be adding more oil again in a very short time and also this is dangerous cause the oil can get on the brake pads and cause brake fade when you need them.
Good luck.

I renewed front sportster forks but when on bike the forks do not come up


If you put it all back together right then you got to have to much fork oil in the forks. Take the screw out of both forks and push down on the front end and it will squirt oil out. put the screw back in and see how it rides. If it is still to hard then do it again till you get about 2 1/2 inches of travel in the forks and then your good to go.
