So I was riding yesterday with friends and for the first time ever,
the bike stalled on me and kept stalling as I went home.
The bike was running great til I got it up to 170 MPH on a straightaway
Then about 10 minutes later is when the problem started.

About 85* ambient temp
Engine temperature hovering around 195*
Normally I wear ear buds and listen to music but mp3 player was dead
And I noticed in 4, 5, and 6 gear the bike makes kinda a whining sound.

The dying feels like it is running out of gas, like bogging out or something.
On my way home I managed to keep it from stalling most times by
Yoking the throttle 100% open and closed, no clutch, just blipping it open and the
Bike would not rocket forward like normal. It just barely stayed running.
Even stalled 1 or 2 times doing that though.

I checked the stator and have good voltages
Inspected fuel line for kinks

Maybe fuel filter clogged? It is about time to be changed. What auto f/f will fit?

Maybe a vacuum issue? When searching threads I found people saying about a vacuum hose
under the air box that can cause mischief. What's that all about?
That may be the whining sound I hear.
And is the fuel filter in the same location as the 1st gen mille's?
under that metal plate at the bottom undernieth the tank by where
it pivots when you lift up the tank?

EDIT: NOPE! not behind door #1! just a tank full of gas!

I have to drain the tank?
well fk me.

ok, so 2 small hoses on kickstand side of airbox?
will check it out.
I just had the airbox lid off and was looking down the t/b and
noticed some sludge. And I use Chevron 95% of the time too!
I wonder if anybody has ever tried puting a lil seaform in...

I have tried seafoam. Works but it will smoke like CRAZY for 10 mins afterwards

lol ya.
I put it in my truck. a bottle in the tank, 1/2 a bottle in through mp PCV valve line to clean out the vacuum hoses and the other 1/2 in the oil tank about 60-100 miles
before I do an oil change. truck runs like I just drove it off the lot,

earbuds and music when riding? I would never do that.

It is a very common thing out here.
Even the moto shops stock music devices and ear buds
On their shelves

Just because it is common shouldnt stop you from using common sense.

Well it is either the wind or music.
The music foes not drown out most sounds.
Sirens, horns, louder engines, screeching tires,
I can easily hear all of them.

I ride an 08 Tuono and mine did the same thing thing last week. I rode about 150 miles that day and when I turned on the street I live on it started acting up, no error codes came up or warning light on the dash. Engine sounded like it was whining or almost squealing. I tried removing one spark plug wire at a time to see if one of the cylinders was out but they both seemed to work fine so I put both wires back on and fired it up and it no longer made the noise and seemed to be running fine. I had the tank propped up while I was checking all of this so maybe it was a pinched line or some fuel pump/ tank related issue when it got hot? I drained the oil and checked the filter to make sure there were no metal filings and everything was clean and free of debris so I'm gonna take her for a ride and see if it happens again. Oh almost forgot I too was wearing ear buds listening to my mp3 and didn't notice the whining sound until I got home
