Front fork oil capasity

When reassembling the forks on a motorbike the main spring and all other internal components should be in the fork tubes then add the oil, as to weight I assume you mean fork oil viscosity. Fork oil for general use is usually 5w or 10w but you need to look up the specific oil type for your bike, also the capacity is unique to each bike but you can measure the oil by pouring the required amount into the upright tubes make sure that the levels are the same, use a straightened wire coat hanger and measure the level in each fork so that any differences are reduced so as to not affect the safe handling of the motorbike as uneven forks can be very dangerous.
Look on youtube to find videos of fork oil change etc.

How much oil in front forks?

The fork oil should come to just below the bottom of the threads of the bolt by the o ring. do not use regular motor oil as it doesn't have the correct viscosity that fork oil has. Make sure both forks have the same amount of oil to prevent an unbalanced feel to the front end

What viscosity and how much Fork oil

If you are rebuilding your Forks, I would STRONGLY RECOMMEND replacing the fluid with Synthetic (last Longer) and is cleaner for the internal Valves... Viscosity will fine tune your suspension. you need to take into consideration your location, your riding weight and riding habits... The lower the number the more action, the Higher the number, the slower the response and harder ride but when you take into consideration Weight and Normal Ambient Temperatures... You need to dial in your own number...

2003 HD sportster - forks don't leak, bottoms out when front brakes applied

You may not have enough oil in the front forks or you may been a heavier viscosity of oil. I'm sorry but I don't have the oil capacity for your "Low Sportster". All I have is for "Hugger" models. They take 10.7oz. "wet" and 12.1 "dry". The difference between "wet" and "dry" is that if you simply drain and refill the front forks, it's call a "wet" oil change. If you disassemble and clean the forks of all oil inside, it's called a "dry" oil change. Contact the service department of your local shop and ask them how much oil goes in the front fork. To change the oil, there is usually a small screw in the trailing side of the lower fork slider down near the axle. Take these out and the oil will drain to a certain degree. Hold the brake while working the forks up and down with your weight to get all the oil that draining will get out of them. If you want all the oil out, you'll have to disassemble the fork tube. I would not do this if the seals are not leaking. Replace the screws in the sliders and then remove the top cap from one tube at the time and refill the tube with the specified amount of oil. Sometimes, the top caps can be difficult to get back in due to the pressure of the large spring in the front fork tubes. You may need a tool to compress the sping. I'm not sure on the "Low" model. I've always managed to the top caps back in without any special tool but I've never done a "Low" model bike. Harley uses what they call their "Type E" fork oil. I do not know what the viscosity of this oil is so I always use PJ-1 30 weight fork oil for most applications. Use only fork oil as any other oil may have a tendency to foam thereby negating any dampening action of the forks. If this doesn't solve your problem, you may want to check into changing the springs in the front forks. Progressive Suspension and others make kits for this.

Good Luck

Ok two things. one is i have a lot of backfire on my 05 electraglide. i took it to a dealer and was charged 500 bucks for a new programmer. still backfires. two is can i add air to my front suspension,...

For the bottoming out, change the fork oil to a higher viscosity grade. Also, if your shocks have been leaking oil as seen by dirty, greasy fork tubes, you should change the fork seals. If leaking, and if bottoming is only recent, you can refill with the fork oil viscosity recommended originally (you may just be empty). Only increase oil by 5 wt at a time. I don't remember what the factory recommends but should be in your manual.

My 2011 fat bob has a lose of power when you let off throttel the front end dives

Since your bike is a 2011 model, I'd take it to the dealer and let them check out the loss of power. On the front end diving, you may need to put a heavier viscosity oil in the front forks. You'll have to drain the forks and then refill them with the proper amount of oil of a heavier viscosity. I think the forks come with H-D type "E" oil that is supposed to be about 30 weight. Use only "fork oil". You cannot use engine oil.

Good Luck

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

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
