How much oil do I put in my forks?
typically you would overfill the forks and draw out the excess oil with a syringe/tube that is set a specific distance below the edge of the top of the fork tube, in roadracing you will see a lot of bikes running between 90-110mm fork oil level.
What happens if you overfill fork oil?
To make matters worse, overfilling the fork with oil can damage the fork seals causing them to leak. If this happens, the seals must be replaced.
How often should fork oil be changed?
The oil in your fork loses lubricity, gets dirty, and should be changed every 10,000 miles or once a year. Here’s the quickest way to do it—and, yes, we know there’s a better way to do a cartridge fork.
How often should you replace fork oil?
So what’s a reasonable interval? For sportbikes, simple replacement of fluids and seals at 10,000 miles will bring new life to the bike. Touring bikes and cruisers can probably double that interval before the service will offer noticeable improvements. But whatever the interval, it’s certainly not “never.”
How much oil does a front fork need?
Many modern forks contain only 5 or 10ml of oil for lubrication; but this is all it needs to keep the system running smooth.
How is oil height measured?
Insert the dipstick into the tube slowly and push it all the way down. Now withdraw it and look closely at the tip, which should have oil on it. If the level of the oil is between the two lines, your vehicle has enough oil. If it’s at the low mark or below, it’s time to add a quart.
Can you add fork oil through bleeder?
With the forks off the bike, take the air-bleed screw out of the fork cap. Turn the forks upside down and place a graduated cup (the syringe with the plunger removed works great) directly under the air-bleed screw hole. Gently compress the forks by hand to force oil out of the fork.
How often should you change fork springs?
Every 2 or 3 years is probably what most people will do (6-10K miles). The shock really shouldn’t go more than 2 years since it has a LOT less oil to begin with and gets worked a lot harder. Depending how many miles you ride every year it’s not a bad idea to replace fork seals every 12-15k as well.
Is it normal for fork seals to leak a little?
Seals Leak From Normal Wear and Tear Because they have a hard life, you should maintain your fork seals or change your seals after 40 hours of riding time.

Can I use engine oil as fork oil?
