After a few test rides with varying tire pressures I could not get rid of the wobble between 25 & 35 MPH. I used the front steering assembly from my 1983 Gold Wing Aspencade with air suspension. Disassembled the front steering stem and removed the forks. Found damage to upper & lower steering stem bearings and the fork fluid was pink but smelled like 90W. Cleaned both forks and filled with new Dexron transmission Fluid. Replaced both steering stem bearings and torqued to 16 ft/lbs which is 5 ft/lbs higher than the spec. With 32 PSI in the front and rear tires, the trike handles like a dream. Problem solved.
