On the G5 expert, it is very common for the engine to run on 1 cylinder at the first cold start. The spark plug of one cylinder gets dirty. After replacing the candles, the snowmobile is working normally. Until the next cold start. This does not always happen. Moreover, this problem occurs on many G5 summit expert snowmobiles. Candles are installed in the position as indicated in the manual. The gap is turned towards the ETEC nozzle. What could it be? There was no such problem with candles on the G4.

Haven’t had a problem with mine.
I have this exact problem with my 2024 G5 expert N/A, fouls plugs on cold start up. I change both plugs for new ones and run like a champ for the day.
The colder the outside temp the worst it is: at -23C it started first pull but died after about 8 secondes. Once again put new plugs in, starts right up and good for the day.
So far the dealer has changed the ignition coil, both Etec injectors, ECM, engine temp sensor, Mapts sensor to no avail.
Scratching our heads right now.

Do not touch throttle first 20 seconds just let idle. Try that
Yes, that's the way it is. But it doesn't help.
Are you running ethanol free fuel?
