Engine Noise (whining/squealing) after V7 Stone Oil Change?

[ackattak]

Hey gang. I'm new here, so forgive me if this topic has previously been addressed.

I have a 2014 V7 Stone. Yesterday I completed its first oil change after the break-in period just shy of 5,000km.
Did it at home myself by following the guidelines in the manual + got my oil and filter from my MG dealer.
It went pretty well. Tightened all the plugs back up. Filled 'er up with 1.6-1.7L of synthetic 10W60.  Checked the level and it was definitely high enough. No discernible issues.

But then after about 10 minutes of city riding, the engine started making a whining/squealing noise. I stopped immediately but couldn't seem to figure out what was wrong.

No leaks. The oil level was still high. The bike didn't seem to be running rough or vibrating or revving abnormally. Only issue was that whining/squealing noise. Plus, said noise would only happen when I was using the throttle while in gear. When the bike glided with the clutch pulled in AND during idle it sounded/felt 100% normal.

Any ideas what could be going on here? I don't wanna ride it because I'm afraid damage may occur.

Thanks!

 Sounds like a clutch issue , or gearbox . Did you drain the gearbox , what us Americans would call the transmission .

No, I didn't drain the gearbox. Didn't think to do it because I'm still at least 5,000km away from that specific service interval. Would that still need to be done with a dry clutch?

 No . The reason for the question is that the nomenclature used in the manual is confusing . The final drive , or bevel box , is labeled transmission , and the transmission is labeled gearbox . Leads to what we call a transmission being WAY under filled . You say the squeal only occurs when the bike is in gear and the clutch engaged , correct ?

Ah. I see. Okay, then no, definitely didn't touch the transmission either.
And yes, the noise only occurs when in gear.
Any idea what to fill it up with? Having a hard time tracking down fluid specs for my bike...

 I think the owner's manual gives specific oil recommendations . Sorry , not really an expert on small blocks , we need Kev m or Pete Roper ,or Guzzisteve here . A search on WG should provide the needed info .

 Oh , and yes , don't ride it until one of the smart guys here weighs in .

Did you happen to notice if the oil pressure warning light was on when the noise came about?

[guzzisteve]

All you want to know.

Nope, no warning lights at all.

Ok, I was going to guess that perhaps the seal to the oil filter failed or slipped, then suffered a loss of oil pressure.

You said you changed the oil at 5000 clicks and after the break-in period. Does that mean you changed the oil after break-in and then again at 5000 or just once at 5000?

[guzzisteve]

Thow-out bearing, add oil to the foot shifter transmission. I have seen low quantities from factory.

5,000km was my second oil change after the initial one at 1,000km after break-in. So my bike has just under 6,000kms on it.

Awesome. Thanks for the intel.
Just one more thing because every manual/shcematic I have found has said nothing about the gearbox:
Where is the oil fill hole? And is it 85w90, the same as the rear transmission/bevel?

I'm definitely not due for a gearbox/transmission oil change at only 6,000km, but if the factory levels were low this could explain it...

[Kev m]

Wasn't the transmission/gearbox oil part of the break in service?

[ackattak]

Wasn't the transmission/gearbox oil part of the break in service?

I would have thought so!
It's been over a year + 5,000km since then, but still. If the factory didn't fill it up all the way I would've expected that to be done at 1,000km for sure.

Also, I've never had this issue before up until I changed my oil yesterday. It seems like the two things should be related, but if it's the gearbox, that would be a complete coincidence.

Gearbox is 1L of 85W90, bevel box is 170 mL of 85W140.  Not good to mix up either oil type or quantity.

[guzzisteve]

Fill the rear drive thru the big level hole or top vent hole.

Yep, that I was able to find that out thanks to the guide you linked me (Cheers!)
But I'm more wondering about the gearbox itself. It doesn't seem to come up in that guide or elsewhere I've been looking so far.

@sib thanks for the quantities list!

Pete's advice to me on the old smallblock transmission was always just to drain it and fill with the measured proper amount through the fill plug (side of transmission, right behind the rear brake linkage if memory serves, partially hidden, sometimes easier to access if you remove or reposition the rear brake guard).

Fill it on its sidestand with the proper amount, don't worry about it being level with the plug or not.

Perfect. I actually just had a look and know exactly what you're talking about. She is indeed looking a little dry in there so I guess that's most likely the problem after all. I'll pick up some 85w90 after Labour Day and set her right.

Thanks a lot for the guidance, you guys!

Drain out what's in there and measure it. If it's only got 170ml in because the people who did the break in service got the volumes wrong the gearbox will be scrap.

Pete

[Vasco DG]

Without dying in the arse? Yes, probably, but all the case hardening on the teeth would be damaged and the screeching is the bearings under the pinions giving up the ghost.

[Chuck in Indiana]

Good to know .

  Dusty

Not good for the OP to know.. Jeeee sus. Not yet *another* under filled transmission by some "technician" that cross threads your spark plugs? 

[Kev m]

Crap, does this raise the question whether or not the OP should bring it back to a dealer (selling or other) to have them document the drain and refill? And potentially start the warranty paperwork?

Hell YES.

[Bob Wegman]

If the dealer did the oil change and didn't put the right amount of oil in the gearbox, I would bet they will get a refusal for warranty coverage and have to eat the repair themselves.  Ugly.

[Vasco DG]

I've had this problem presented a couple of times at my shop. Last time was a Nevada, was serviced by a shop down the coast, they refused to do anything point blank. He ended up having to eat it. We got a second hand box from Pinwall.

That works suggest another dealer be involved to document it for the law suit against the original dealer.

And, if the dealer is acting as official agent, then Piaggio NA should be named as well.

This does not sound good.  This is the reason why I have taken a vested interest in doing my own work. I hope we're wrong.
