Strange wobble/vibration from rear of scoot By junkxj (Read 294 times)

This is a random question, but has anyone had a bad wobble that feels like the rear wheel is out of true? Checked the wheel and it seems straight. Thinking it might be the motor mount bushings letting everything move around more than it should. Any ideas?

Did you check the air pressure, also check for movement left and right on the wheel. Check your motor mount bolts and all bolts on the swingarm. Also check your Shock brackets one could be broken.

The wheel seems tight, I had it off to check it and made sure to tighten it down. All the bolts are tight. Shock brackets are good. What are the chances the bushings are bad?

Very good chance of motormount bushing loose. I found them bad on a 50 I picked up last year. Not all that bad a job to change. Mine I found moving around with the weight of scooter on ground just shaking it side to side.

If you put it on the centerstand and rev the motor and spin the rear wheel if it is the wheel you will feel and see it.

The wheel looks like it moves, but I checked and it is true. The wheel bearings are tight. The reason I think its the bushings is because when I hold the front brake and give it gas it looks like the entire motor shifts forward and up . I don't remember the 50 I had doing this.

When cold grab the motor by the head and try lifting it up and down and see if it moves.

Sounds like the rear motor mounts are shot...
