Question Morini Troubleshooting

When ever I let off the gas and start to slow down my motor makes a growling/groaning sound. Even after coming to a complete stop it will do it for a few seconds. Sometimes it's so bad I feel it in the seat and handlebars. But it does not do it all the time.

I suspect it is in the clutch but I am not sure. Anybody have any ideals?

I am by no means a Morini expert, but that sounds like a bearing going bad or a poor fitting bushing allowing the shaft/part that it supports to oscillate. My first hunch would be clutch related. Again, I am no Morini pro by any stretch of my imagination.

maybe it's growling because it's mad at having to slow down...

I think your motor and clutch are tight and needs to be broken in. Mine took at least 20+ hours of riding or close to 1000 miles before it started smoothing out.

I pulled the clutch cover off and everything looks okay. The only thing I notice is a little play with the shoe hub but that could be normal?

Here is some more pics plus a video of the play in the hub
