Default Starting an EFI ?

Not sure it was doing this last yr. About 10 degrees out & when I hit the Ele start it starts but idles very low. Blip the throttle & it stalls. Hit the starter again & it starts & goes to normal idle. Motor is still cold but wondering if thats normal or maybe time for some fuel injection cleaner or ? It does seem to run great otherwise.

It wouldnt hurt to put some fuel injector cleaner in.

Its nothing to worry about unless it gets worse, I would just shut sled off and restart if idling to low.

My 99 Zl 500 and 03 Zl 800 use to do the same thing, 1st time starting for season and after sitting for a few weeks. I would do as Fun11cat said, shut it off and restart. both sleds had 10-12 k miles when I sold them. the 800 is still going good. I just talk to the guy yesterday who bought it last year.

Yep. I have comoketely removed the electric start for machines that bothered me like that before, crank them with the rope and they would always start faster and run correctly.

I’ve had 3 cat batteryless zr’s and they all have done something similar. Very first cold start of the day they start on 2nd or 3rd pull, idle very low for about 5 seconds then it switches and idles high for about 10-20 seconds and eventually drops down to its final idle rpm. During the first 5 seconds of very low idle if I touch the throttle it will die, I leave it alone and it comes around. All starts after that during the same day skip the 5 seconds of very low idle.
