I have a 1995 Gold Wing with a Motor Trike conversion. During the last two years, this is the third time I have had it in the shop trying to get rid of a high speed shake. On the interstate usually at 60+ MPH, after hitting a bump or going on an overpass, or when it is extremely windy, my trike starts shaking violently - the entire trike. It is so bad, that people following me can see the shake quite easily. I slow down a bit, and it quits shaking. I have had two mount brackets at the front welded, front tire replaced two years ago, back tires replaced this year and spin balanced, also had to replace the drive shaft this year, because as I took off one day, there was a horrible clanking sound.
Now my trike is in the shop again still trying to get rid of the shake, and I am told that it needs two new progressive air shocks. I believe them that the shocks are shot, but the ride wasn't bad, except the shaking at high speeds. If I thought the shocks would fix the shaking, I would replace them immediately, but they said they can't promise that will fix it. Have any of you had the same problem, and how did you fix it? Thanks.
