Progressive Fork Springs - How much fork oil to use?
Hi All,
I am about to install progressive front fork springs in my Street Bob.
I thought that while I am installing the springs I might as well change to SE fork oil.
Since progressive springs displace more oil, does anyone know how much fork oil to use with new progressive springs?
Progressive recommend using special oil measuring tool, but I don't have one.
So if anyone has done the install and measured the amount of fork oil required, I would appreicate the heads up.
Thanks

There is two flavors of the progressives. the stock length = no drop and the "lowering kit" which will drop it up to 2", you cut the spacer to size. Which did you buy?
Btw, PTE, you may want to revisit your #1.

progressives with 15wt. will ride like a dump truck and skip over bumps. Better off using stock weight oil. You can cut your spacers that come with the spring kit to better set your sag(preload). If you cut the spacer to the firmest recommended length above the fork tube, you will have a firm ride. It will be like setting your rear shocks on the firmest preload setting.
