Ok- Please help me with some direction.

What oil level are most of you running on these? Generally?

I have turners with very different options- 265 all the way to 400-

I understand it depends on valving, but the range should be closer than the differences posted eh??

360ml TT from Belgium speced mine, I ended up going to 320ml cause the forks were too stiff, they sent me a new shim stack specs and now it's perfect at 360ml

So apparently there’s 2 different types of kits? One has spring tubes, which doesn’t take as much oil??

Enzo has national style spring tubes as an option for his KYB kits.

He told me 325 w spring tubes .360 with stock spring seats.

spring tubes give a bit less mid stroke harshness/ spike as you raise oil level.

The difference in oil amount was what the spring tubes displaced over stock seats.

Less restriction & oil is further away, lower before it hits gets to the restriction of the tubes.

Your filling space above spring seat vs stock seat.

lower oil more free movement before oil hits restriction at seat/ tube.

Mine had 375cc and was kinda harsh and couldn’t use the whole stroke. Dropped 30cc now good to go 170lbs.

I think this might be related to how you also handle inner cartridge oil. It should be filled up with oil all the way to the drain holes with the rod in fully compressed position. Should be almost impossible to get the comp unit into the cartridge (with rod fully extended of course).

Then push out excess oil by compressing cartridge a few times all the way to the bottom.

If you have say 180ml oil only and assemble the cartridge it makes a big difference.

I have cased a lot of jumps and had short landings, and with 300 it is holding up just as good as my CV forks Smile

Just adding a note here since I'm getting some spring tubes this week. The difference in oil between setups seem to be related to what spring tube or spring perch is used.

Some KYB kit seem to have the standard one, and some seem to have the factory version which is way more restrictive. Plastic and aluminum std shall be same flow.

360 with factory perch is just damned stiff. Technical Touch set it up like that but its not rideable. As mentioned above, even 300ml oil I had no bottoming issues. But it did ride a bit low.20240312 221351-COLLAGE.jpg?VersionId=tdnJ4
