2025 rocket 3 prolonged occasional starting.

Mine does that every now and then. Not sure if it's the same issue, but sometimes when I hit the starter it cranks over fine but won't start. If I let up on the start button and then press it the second time it always starts instantly. It's almost as if something in the ignition circuitry isn't turning on with the first press of the button but works fine on the second press. I've just gotten used to it and now if it doesn't start immediately on the first press I just let up and hit it again and it always fires right up the second time.

Could it possibly be the fact that you use premium gas? Unless you have a tune these bikes are made to run off of regular unleaded. If I fill up at a discount gas station I use mid grade but have never tried premium and have never had the issue you are reporting.

One thing you can try (and it's free) is when you click the rocker to ON and hear the fuel pump prime, give it an extra 4 seconds before hitting START. It could be simply the fuel rail isn't suffiecently pressurized before you hit the start switch.

Noticed the same. Always starts, but maybe 1:10 it’s a 2-, almost 3-sec chugga-chugga and a puzzled look. Seems to be on cool mornings (40’s, 50’s), so i chalked it up to running 15w50. Maybe that’s not the cause; don’t know. New bike, 8800mi
