Metal in Oil.....

[Mike Tashjian]

Kick stand springs on my Stone would vibrate and sounded  like what you are describing. I wrapped one spring with some heat resistant wrap and all has been good.  Mike

Run your kickstand springs through rubber tubing and zip tie so it insulates.  That keeps them from making noise and worse -- rubbing through.

Chuck, yes it does, and not that I can see.

Side stand spring? Humm..Easy enough to check on my way home when the noise is there. At a light just kick it out and see if it goes away. That would be too nice and easy!

Thanks,
Tom

I chased an engine noise and vibration in the Strada for much longer than I would like to admit. I had a stethoscope all over it and couldn't find the source. I tore it down and balanced the whole rotating assembly. It was a harmonic in the crash bars. 

[Tom H]

I will look at that. Of all the bolts that I made sure were tight, the engine guard and frame bolts I did not check when I got the bike.

I tried the screwdriver technique. When I listened, it sounded like the back while I was in the front and vise-versa. I hate to pull a perfectly sealing timing cover. But I've tried almost everything to track it down. I'm sure that if it comes to that I will find nothing wrong, again only 15K miles.

After I try the last bolts and side stand. I may pull the fairing and ride it and see it it may be something with it. I've tried to think of the best way to describe the noise....The best I can say is that it sounds like something "rotating" and rattling against the case lightly. it makes it's sound and then pauses for a moment and then repeats. Checked inside engine via the pan and found nothing unusual. Clutch? As mentioned, couldn't get the sound to change via the clutch lever.

Thanks again!
Tom

I chased a noise on my Honda CX500 for some time....
Turned out it was the sunshade visor in my helmet... 

[twowings]

Riding this weekend exposed a new metallic vibrating sound that increased with engine revs...Great! I thought, what's wrong now?

*DOH!* I had added a metal beer opener to my bike key ring for those back-at-camp emergency beverage situations...sure enough, it was laying just right to cause buzzing on the handlebar clamp...problem solved! Hope yours gets resolved, too...

Can anyone confirm for sure the correct rod BOLT torque setting is 60-65nm?

Can anyone confirm for sure the correct rod BOLT torque setting is 60-65nm?

Yes, oiled screws:

Engineering drawing in pen and ink.  Another lost art.

[RayB]

I can still ink on linen but there's cad so there's no demand.
The art is not lost...nobody appreciates it

Ok time to update this.

I'd pulled the bearings and they were fine so ordered new ones.
Put them back in and due to being a bit of a knob, I misread the torque wrench and over torqued the bolts on the first rod. What a dick. 
I decided better safe than sorry and ordered two new rod bolts. $51 each and 2-3 weeks ex Italy. Damn, Oh well.
So 5 weeks later they arrive 
Put it back together yesterday and cranked it up.... It went! And kept going!
Rode it for 200km with no issues. The rattle I had heard is gone, confirming it was the loose muffler.
All is good in the world 
Except it's pissing down with rain today 

So, all I can put it down to is some random crap being stirred up by a slight oil over fill and a hard all day ride.

Thanks again to those who offered suggestions.

[LowRyter]

damn, all this for a loose muffler.

As ol' Darrell Waltrip would say, drive that bit%h 'till it blows. 

[Mr Revhead]

The rattle just made me suspicious, the metal in the oil made me scared, I've never ever found metal in the oil in anything I've owned that hasn't had a failure....
