I just rebuilt mine and I had to move up to 15W oil to stiffen them. I am 230 lbs. Are they stock or YZ forks. Many people dial/swap the WR's forks to be stiff like a YZ. The YZ's are much stiffer for jumps/braking. KJR

Hi Creeky. That`s what I`m thinking, but as I set them up according the manual it`s a little confusing

My service manual says standard oil level is 125mm from the top of the tube with the springs out and the fork and damper rod collapsed. Minimum oil level 150mm, maximum 80mm.

yeah my manual say`s 125mm for europe and 135mm for the rest of the world, I`ve got it at 135mm but I`m thinking of syringing out 5mm at a time and seeing how that goes

Great, glad you got it sorted out. Unusually wet conditions here have precluded riding for some time. It finally dried out enough to get some seat time on my WR the last two days, felt GOOD. :prof:
