I didn't mean to convey an a**holish attitude, sorry.

Yes it is a stick of sorts that is graduated and the point is to overfill past your desired mark then stick the tube down into your forks after setting it up to the desired height and draw off the excess with the syringe. Works flawlessly every time and really helps get your levels right so you can get your forks setup properly.

 

I wonder if there is a difference between the TC forks and the EVO forks.
What I mean is Can the measurements from a TC be used on an EVO?

I do know that the service period for EVO forks is shorter than that of the TC.

 

Most of the forks I have ever worked on fell into a range from 115mm to 155mm from the top. The measurement is not an absolute, it really lies in what type of spring you have in there and what length your spacers are to get the correct sag, free and loaded.

 

So basically without a reference number the measurement method is of no use on an EVO.
Is that what you are saying?
Or are you saying just take a guess from 115-155mm?

 

If it were me, I would check a newer version of a service manual to see if there have been numbers assigned. In the absence of any other reference I would start conservatively by setting the level at 130mm. I am not sure how this relates to the quantity method of measurement on your specific model but the measurement is taken with the spring in the tube and with it completely compressed. This should leave plenty of air in the tube and if anything will make it very soft. Your mileage may vary. You can then set it 5mm at a time to get a good setup. Remember too much fork oil and it will lock as there will be no room for it to flow and create the damping action. The other very important factor to consider is the viscosity of the fork oil AND the types of valves you have in the forks.

 

Progressive tells you to reference the service manual lol

 

Since your new springs displaced more oil than the old ones you had no choice but to use the height measurement as your reference. Did you adjust the level one way or another to get the feel you wanted?

 

You measure from the top of the fork to the top of the oil level while the tube is vertical and the slider is compresses. HD makes a gauge pn. 59000A for the challenged, You need to slowly pump the slider 8 - 10 times to exhaust the air. FXDC / FXDL, FXDB, is 3.74 inches, FXDF 6.18, FXDWG 3.74

If I was going to adjust anything it would be by changing the weight of oil, I stayed with type E. At reccomended level... For now anyways
