Stall at cold start

[Jalingo]

Did the diag code 03
The number changed when I was pushing the start
The bike kept wanting to start but not ( guess is normal)...

When in the diag mode none of the codes will allow the engine to start.

Thanks ionBeam
Spoke with a Yamaha technician this morning , told me that the reflash can be only beneficial

Told me that if can’t start it while I’m going down south
Just do what I was going and should be fine

Once I get back , I’ll check the hoses and see if there’s something clogging them

Air Intake is clean

If it is the hose to the sensor, it isn't going to get better...
If the error code (14) reappears, you need to deal with it.
Not hard to fix but you have to lift the tank and remover the t-bar and heat shield to get to it.

Hi Ross,
I’ll clean the hoses when I get back from the trip ,

Codes appear only on diag mode ?
Or they appear on normal display when you about to start the bike ?

I'll answer for Ross, he can come along later and straighten out my post if necessary.

In the Fuel Injection System part of the FSM, it isn't exactly clear that there are Fault Codes and Diagnostic codes.

If your motorcycle has a solid fault, the ECU will display the Fault Code(s) on the Meter Assembly, along with a flashing or solid Check Engine light. The fault will be stored in memory (diag 61) and will increment the fault count in memory (diag 62).

When you go into the diag mode you are reading the whole fault code table, item by item. The next table is the Self Diagnostic Code table where you can dynamically check results, and then there is the Actuator Codes table from which you can switch and run items. Finally, there is an additional table that shows the fault and it provides detailed trouble shooting information for each Diagnostic Code and sometimes a Reinstatement Action you need to perform to clear a code from memory.

A partially blocked MAP sensor hose won't necessarily show a fault code.....
Other things to check..... that the idle speed is set to 1100 rpm, and that you don't have water in the fuel.... add some Seafoam to fix that.
But do a bunch of things at once and you won't know what the cause was.

Idle is set right ,
I’ll do one by one, to eliminate gradually of course

Sea foam does not “dry” the inside of the engine ?

Yamaha dude told me that
I poured some sea foam sometimes inside the tank when I was filling up gas , till now nothing wrong

[raYzerman]

Seafoam (like a lot of fuel conditioners) is mostly naptha, a slow acting solvent to take care of gummy deposits. Seafoam also contains isopropanol (a lot of the others don't), and this disperses water really well if you have "bad gas" or ethanol fuel that has phase-separated after a coupla weeks. No harm in it at all, it's pretty mild shit and very basic chemistry.

Ray, you uneducated purveyor of untrue information. Why, just look at this video and see where you have been mislead



I saw it on the internet, it must be true. It's not like Mr. FortNine is putting out videos for personal gain, regardless how valid his 'factual' reviews are.

Hmm, mebby Ray was right after all, in spite of the video.

[raYzerman]

FortNine videos were good in the beginning, are now just becoming entertainment.... not scientific and leading people astray........

Found this !!

Went to Ivan’s , reflash makes the throttle more responsive ,
Bikes Runs cooler than before ,better acceleration, Mpg is fantastic , at 80 mph constant with throttle lock was doing 47 mpg

Did cleaning the tube make the problem go away?

(I have been considering the Ivan flash but I am pretty happy with the way my 2011 is running.)

I’ll see overtime if the problem occurs
If still , will not be from the hoses and the air sensor cleanse

Ivan was nice and lovely , definitely knows what he does
