Vibration in 1500

Postby eastkytriker » Sun May 04, 2014 6:26 am



I have a Goldwing 1500 motortrike conversion and It has developed a vibration somewhere beneath the fuel tank. It is intermittent but you can feel it through your feet on the pegs. Me or repair shop cannot locate it. It seems to be getting worse. Any clues?

A better description of the vibration would be good. Is it at all speeds, on decel or what? The Gl1500 alternator will cause an intermittent vibration when the rear bearing begins to fail. Also when the rubber dampers get hard with age.

The vibration comes when you are up to speed and leveled off, like on level road at 65 mph with cruse on.

This may be a simple tire balance issue. Have u noticed if the vibration dissipates, or disappears completely when the cruise lets off the throttle? It may be difficult to discern this while using the cruise control...ride the bike up to speed where you're feeling the vibration...let off the throttle...if the vibration goes away with any significant notice to you, you may be dealing with a bad u-joint on the driveshaft. If the vibration persists unchanged (aside for when overall speed diminishes,) you're likely dealing with tire balance issues. Another test you can do while riding at the speed where you're noticing your vibration...can you effectively alter the frequency of the vibration simply by pulling the clutch in?..or by changing the engine RPMs? If yes to either of these may indicate a clutch\transmission issue or engine issue such as the previously mentioned alternator parts.
Hope this helps, keep us posted.
Keep the rubber side down.

Trikes are known for eating U joints and to check you HAVE to have it removed and in your hand.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

Thanks for the reply, I had the driveshaft out and lube the splines and rear u joint the front one is sealed, but didn't have the u joints out of the shaft, I guess I need to look closer
