R1 04 Fork oil change made easy - DIY 

Put a towel under it and a wide piece of wood. Not even a scratch

R1 just weights 180kg, on a heavy bike I would not

Nope, no steps skipped. After new oil you should always re adjust your suspension settings. For changing internals, yes. This is just oil.

I believe that is if you're taking everything completely apart in the forks and doing a full service of the forks, which really isn't necessary unless something is wrong and you need to. For a Fork oil change, this is really it. Not many tools required.

Same weight and level as oem, made a Hugh difference. Before the bike would feel unstable and not able to get my knee down, now it runs smooth in group 3 on the track (fastest group) 100% would do this with a bike I bought second hand

measure what you take out, best way! or fill up and measure empty space from top, i believe 110mm or similar

It should be 0.53L but the viscosity I don't know, I think 5W ?

I suppose the best way would be to overfill and the use a syringe with a tupe attached the exact right length to remove all the oil above the disired fill line ...I believe it how the pros do it rather than attempting to go off measured amount which will probably not be accurate due to residule oil clinging inside etc...how much difference could that make? idk but what I want to know is would lighter help if the oem forks are sluggish? going from 5 wt down to 2.5? Or mix 2.5 with 5 wt to have 3.7

@@Force242 standard is 5W, you could go with 7.5W or 10W if you want a stiffer feel or if you're heavy but it's not necessary
