Trike is now 90% done, so I thought I would take it for an experimental ride. I used the front forks/triple tree assembly from my 1983 Goldwing Aspencade with air suspension. At about 25 to 35 mph you feel a wobble. It gets worse when you take one hand off the bars to shift gears. Seems to clear up at about 45 MPH. I have "old mock up tires" on the back and a new tire on the front and don't know how much affect this has. I know the dreaded "goldwing tank slapper" and this is pretty close to it. I understand it's a wide open question, but I could be missing the obvious so any help would be appreciated.
