155 mm
BUT if you have stock springs which we all know are mush, you can add more.
I'm currently running 125 mm with aftermarket 0.925 springs.

do any others have any input on running slighly more oil in the forks. I know when i rebuilt the forks on my CRF250 i added an extra 25 or 30ccs of fluid. But i have never dealt with a single chamber fork like these.

155 to 125mm doesnt seem like you would be close to overfilling and thusly causing problems with too much pressure buildup... and i wouldnt mind a lil more compression dampening when i go and rebuild the forks on my 919.

The RaceTech build sheet said to start at 140.
I did.
Then I went to 135, but to be honest, could not tell the difference.
Wanting more compression damping for only the turn at the end of the half miles straight we have, I took added another 10 mm to end at 125. That's where I'm leaving it. While this is not "info from others" as you are looking for, at least is more info for you to have.

No problems at all.
All my road riding and over 600 miles of track day mileage was done with that setup.
I can still get down the forks down to the hydraulic snubber zone but they are not bottoming out.
The front end works nicely. (fully kitted)
