Morini Troubleshooting

[Dave31]

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.

 

[bairdco]

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

 

[foureasy]

i agree with bairdco

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.

older motor, gearnut might be right..newer motor, easy rider maybe right

new motor...my bet's with easy !!!

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

Hmmmmm..... I really do not like what I see in your video. That is a boatload of free play on the clutch drum. I wish I knew what is considered acceptable play for your Morini clutch. Some clutches are happy set up like that, but most all clutches I have worked on...... that much free play means the drum hub bushing/ needle bearing is toast.

Yeah I am not sure myself and I suspect thats what I am hearing. Not having any experience with these clutches I am unsure. But I do know I dont like it.

I heard that noise the very first time I rode it, second time nothing. Third time nothing, but did it the fourth time.

I'll take my cover off this weekend and check to see if that play in the bell is normal. It also gives me a chance to change my clutch oil.

I had strange noises as well. It sounded just like the rear tire was rubbing it was not rubbing. I switched to Bell Ray 80w gear clutch oil same as Easy. That helped chatter a ton. The rubbing thing went away for me over time. I suspect the shoes have to brake in and seat a little. I am curious to hear how much end play Easy has? Mine has free play as well.. Probably fine.

I have several Franco Morini Motors, Break in is 500 miles. So.. Go easy for the first 500 miles.. Enjoy the ride...

see? this is the difference between this forum and 'the other'.... here, nobody is verbally spanked for not being Captain Forum Expert.
and also, a guy like myself can go completely off-topic without repercussions. as long as it doesnt become a habit, that is
