    Yamaha R15 Engine Stalling

    Hi,

    I have a new Yamaha R15 V2, done around 2600 KMs
    Well Ridden till now, 3 services Done.

    I have suddenly started facing this issue, When i Start my bike in morning, i always let it idle for 1-2 Mins before riding it

    The Bike Rides fine until i have ridden 10-12 Kms, Then the problem starts
    1) If the bike is in lower gears 1-2-maybe 3. and rpm are lower (arnd 2-4k)the bike stalls for no apparent reason.
    2) and then every time i brake on signal , or bike is riding low gear and on lower rpm it just stalls
    3) Problem is there even when i have the clutch pressed and have stopped in signal or traffic.

    P.S: The Fuel Tank is more than half full


    UPDATE:
    today i observed that, the bike have now started on cold engine also; while idling
    before stalling i found a peculiar sound coming from the engine, tak-tak
    2-3 sound occurrence, the sound stopped and so did the bike

    Also i siphoned out the fuel today; it smelled like it was adulterated.
    water was around 5-10 ml in the petrol

    i regret now inverting the tank




    UPDATE
    The problem was immediately identified by the mechanic, i trust him from the start, a very capable guy

    The problem was with my spark plug CAP, i changed that and also replaced my spark plug, 60 Kms done no issues so far

    Advice is a form of nostalgia.
    Dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it's worth.

      I had a similar issue on my Splendor+. Problem was later realised as burnt cluth plates. Replacement changed the whole story.

      Kindly visit the SVC and let us know what they say.

        faulty fuel pump.do you often ride on reserve?
        burnt clutch plates in just 2500 km is not possible.
        and the question remains why do i race?
        every finishing line is the begining of a new race.

        (:)people keeps on saying add spark to life, bajaj got hold of that idea and added an extra spark to bike.

          What about his riding style? He hasnt mentioned any.

          And his tank's half full. Adequate.

          Faulty fuel pump,could be. But he'd be lucky not to land up like Lijo on the other thread.


          Check electricals.
          Cuz if it was the fuelpump the orange/red light shouldav lit up.

          Random question: what fuel grade are u using, from which bunk?

            I had faced this issue in my previous Version 1. however, i used to get the problem in first few KMs of the ride. during those first few KMs, even at speeds of 60-70KMs, when i used to let go the throttle and depress the clutch, the engine used to shut down completely. however, if I would release/pop the clutch it would come back to life again.

            the fault was an overtightened tappet set-up. check the valve clearance. if those (all 4 of them) are overtightened, u might face that issue.

                well yeah your issue i can relate, whenever engine stalls, even i press clutch and accelarate it comes to life again, but the issue is only after riding for 12-14 km, not before that

                  There can be various reasons:
                  1. Faulty Pump
                  2. FI issues
                  3. RPM issues
                  4. As it's monsoon, there might be possibilities that it's water in petrol!


                  It's best if you take it to SVC and get it correct ASAP, so please run!! before you damage other stuffs!!

                      no, infact thats the first thing in my mind, maybe spark plug gone bad, thats why it acts up, as it gets heated
                      lets see

                          is our issue the same ?, I feel it's the same thing happening with you too;
                          so what did the mechanic suggest ?

                            mechanic suggested a funny thing but working for me..due to heavy rain it is happening..so before parking your byk when there is no shed then 1st open ur tank cover then cover the hole with little bigger plastic(must be bigger than the hole) then close the lid.so that no water drop can enter in the tank..is it clear??

                              This is my Grand Father's technique to preserve Chips/Biscuits airtight in a container. But applying it on the R15 you may take some trouble into your fuel tank. Find the mechanic and kill him asap.
