How to use motorcycle fork oil level gauge change fork oil?

This handy tool helps user accurately fill the right amount of oil into the bike's forks. The adjustable ring measures oil levels from 0 to 300 mm (there is marking on the metal tube) in 0.5 cm increments for precise level of oil, so you don't have to stress over getting the right amount of oil in the forks.

You taught me something. I’ll Be tackling a fork seal replacement on my BMW R1200RT (no springs in these forks). I did order a fork level and was wondering how it’s used (no one ever explained we it to me). Now I understand. Thank you

Such a simple concept. Basically insert a straw of the length of fork tube you want air to occupy and suck until the straw can't reach fluid anymore. Thanks so much going to use this on Saturday for a street bike fork service.

Why didn't you leave spring in ? Won't it effect oil level ? Regards , Bill

so I cant find a measure down for oil height on my WP Apex shocks do you have any tricks for coming up with one? Worst case Im going to measure the one that's not leaking then refill by volume and measure it again then.

how much oil and how should i put it if there is only car tire like air valve on the top instead of threaded cap?

where can i get fork specs for 125 scooters?

I have a KTM 390 Duke with a non-adjustable cartridge fork. Can I simply remove the cap at the top of each tube and take out a little oil with your level tool, without disassembling the tubes from the triple clamps, etc.?

The KTM workshop manual recommends removing the forks before any maintenance. The problem you would have to solve not disassembling the forks is to control the spring compression. If you remove both fork caps the forks will collapse and oil will spill out. If you only remove one cap at a time you will need to prop up the bike and compress the closed fork to be able to unscrew the fork cap from the compression rod from the open fork.
