Klx 250 efi
Hi
I have been out all day on the lanes.
the Klx has been stalling all day on tick over and when applying revs.
it got worse throughout the day, it was touch and go wether I got home.
The last 5 miles were the worse with full throttle I could only do 20mph.
i got it home and switched it off, tried to restart but just turned over and over.
I let it cool down and tried again only getting it to tick over for a few seconds.
Its like it’s choked up but there’s no choke on these EFIs or it’s automatic.
I have read that resetting the ecu may help so I have disconnected it and will reconnect it tomorrow.
any one with similar problems ?
any help would be appreciated.
cheers Paul

[QUOTE=tooter;553434]Sounds like restricted fuel or air flow. There is an automatic choke and a fast idle cam that rotates the butterfly down to regular idle as the engine warms up, but I don't believe that's the problem. How's your air filter look? If you're not sure, take it off and see if the engine starts.There is likely a fuel filter somewhere. If you have a manual ( sorry, I don't) I'd also check that. Others will likely also have tips to offer.

thanks for the reply Tooter.
ecu reset nothing
new spark plug nothing
washed air filter.
tried fuel cleaner and it seems better but still struggles with missing under load.
it’s ticking over without stalling and revs up quite easy but it’s still poorly.
It struggles to start once stopped. But once started it revs up without stalling now.
think it was a bad batch of fuel but others filled up at same time and they’ve had no bother.
