engine just cut out

[Volvi]

Yesterday I had to go into the city, parked there 1.5 hrs. then back home. It got to 38 degrees, just as I rode down the pathway of my home to garage the engine suddenly without any splutter or warning cut out. Tried re-starting but wouldnt fire up. walked it into garage and said aint gonna bother now, to hot will see in the morning. In the morning a slight hesitation in firing and like fuel starved initially but got going after a few secs. idled ok in garage.

So what could it have been? air bubble from heat? vapour? tank was quarter full and Im running Ultimate 98.

I would be betting you got the dreaded vapour lock.
Especially running 98 octane in hot weather.
I suggest you go back to 95 oct for the heatwave period and once again check your fuel lines for possible heat kinking Volvi.

I am surprised that this is the first time you've had it for a 99 bike.

Yeah happened to me a month ago after parking in the heat. Vapour locked..

[Volvi]

filled today with 95 and yea busgo, first time.

i would agree with the other replies above , certainly sounds like vapor lock ...... , is there any way to avoid this , apart from the obvious ?

I guess keeping the pump insulator foam on, may assist.
