revving & bike stalls

Driving through town, malls, parking lots, I'll rev my binge by pulling in the clutch.

Not a huge rev, just a cautionary one.

Yesterday & the day before the bike stalled.

Fortunately it's got a start so I managed to turn on the bike while still on the move.

Why does this happen?

Sounds like a fueling or low idle issue. Otherwise called a flame out.

Tuning issue (too much or too little fuel) or idle too low would be most common causes. Overly tight valves could also contribute. Did you change anything just before the problem started?

Nope.

Doesnt happen every time.

Sort of like after it 'builds up'.

fuel filter

gas cap vent

damaged plug

filthy air cleaner

corrosion on injector nozzle

Did the problem start suddenly, or has it always been this way?

Suddenly started.

Fuel filter was changed 5 hours ago.

I also have a tank sock.

Our fuel is very clean as well.

The others are unlikely.

Bike only has 50 hours of light usage.

I would first check the valves, over tight valve clearance can affect idle. If that doesn't do it I would check out the injector, maybe it's partially clogged or leaking.

where is the idle, that will definitely cause it , needs to be atleast 1300 rpm. if you have a strong idle, but still an issue, then its the fueling set up.

Idle and TPS, my 2012 and now my 2015 would do it every now and again.  I have a bad habit of blipping the throttle due to years of track riding sportbikes, catch myself all the time when going into corners or coming to a stop quickly.  My 2015 was doing it 3-4 times a ride with the TPS at .63 and the XCW map, went down to .61 and it runs perfect - not one pop stall since I leaned out the TPS setting a bit.

 

In addition to the XCW map they both had open end caps too.
