My right one has been leaking a while and was trying to hold out till my rake kit arrives. That will be another 30 to 40 days. Anyway pulled the right side down and found oil seal had been damaged I guess by someone attempt . All sliders and bushing bad both sides. The right side that wasn't leaking only had about 10 oz of oil in it. Before I rebuild them I had 3 1/4 on my forks and didn't take much to bottom out. Both stock springs was out of spec. Love the progressive springs I put 22 oz in the right one and 24 oz in the left one. I used ATF dexron/merc fluid. Rides so much better and now has 5 3/8 free play in the forks. Also found bad wheel bearing and I had ordered some new ones with dust seals. Had to replace brake pads due to the fork oil had soaked them. All is better now and rides like a new trike.

David, with you mentioning that you put 22 ounces in the right fork and 24 ounces in the left fork , I have to ask what air pressure do you have in the two rear tires.
I too ride a Trike.
