Vibration on decel and accel.

Postby dingdong » Mon Jun 16, 2014 9:21 am



My 93 has developed a vibration felt primarily through the foot pegs. When at speeds above 70 mph mostly on deceleration but on acceleration (just slightly) from a steady speed I get the vibration for a couple of seconds. I suspect the u-joint but want opinions based on any experience with a defective u-joint. Bike has 79k miles. Also don't I need to order the joint and boot from a 97 and above.

I would look at the U-Joint as a suspect first, yes. The U-joint has the same part number across all 1500's, but I do recall that the newer ones (97 and onward) used stronger Valkyrie joints. Also use a new boot from a Valkyrie, they are larger and more resilient to wear than the GL1500 boot, and fit exactly the same. The newer Valkyrie joints had a habit of wearing a hole through the smaller original Honda boot.

So does that mean I need to order the u-joint and boot from the Valk or are they now all the same? I looked for part numbers and the u-joint #s are the same but the boot #s are different.
I just reread your post and see that you already answered this.

Dry driveshaft splines will give you a bit of a vibration when getting on/off the throttle when cruising also.Once the load is completely on or off then the slight vibration will be gone.Just seems to be that in between spot that does it.
If I'da known it would last this long,I'da taken better care of it.

I guess I had better get started pulling the rear end off to see what the problem is. At least I have the 76 to ride while the 93 has her operation.

If you do replace the U-joint you need to check it for the cross being centered. Look at this thread for what can happen.
