Fork oil Height

[Yoshi823]

I know that various people use the proper tool from the likes of Race-Tech for getting fork oil height correct, but I found an easier and cheaper method.

When you've finished with the bottle of hand soap, keep the plunger bit.
Cut a length of plastic hose that you need for the air gap from the top of the fork leg ie. 120mm.
Attach this to the pump/plunger piece, lower into the fork leg and pump away...ensuring that you have some sort of receptacle to catch the un-needed oil.

Let me get this right...

You slightly overfill the fork leg and then pump out to the required depth (120cm in your example) ?

I'd much rather get the fork oil height correct than guess that I had the right amount of oil in the fork leg...so I always put in too much, pump the fork leg so's to fill the galleries & get rid of any air, then pump out any excess.
As I said, a cheap alternative to the expensive tools from others.
