2025 rocket 3 prolonged occasional starting.

[Snakeplisken]

Recently I notice if I let my bike sit for a day then try to start it, it won't start right away. I have to hit the start button twice for it to finally catch. I have 1600 miles on the bike. I,ve had the bike about a month now.

I use premium gas and all fluids are where they should be. I have had it happen twice so far. I typically ride it to work everyday and will go for a night ride and never have the problem untill I have to leave it sit due to it raining that day. Anyone ever experience this? Seems like the second time I go to start it after the prolonged first attempt it catches right away.

You will notice this if you havent done your first maintenance I believe.

I ended up putting it in the shop and they startes it a million times and never got it to do it. Ever since getting it back I had it do it 1 more time and hasn't done it since.

I'm pretty sure tight intake valve clearances make for hard starting.

That would be for all weather temps then? My gen 1 cranks long when it's cold out. Warm weather starts instantly. It's not my battery, btw. Just noticed it with the recent temp drop here

The ECM will not throw spark if it senses that there is low voltage....When you try to start your cold bike.....try this crank motor for 3 seconds...stop cranking....then hit the starter again...if it starts right away, your bike my be just like others......

I think so.... I think it should start better as a cold engine than warm though if the intake valve clearances are tight.

Hu, I just tried it, it works spot on. Thanks for the tip.

I am in process of collecting the steel bar, final item before I start but I am also getting a new rear time, it will be few weeks before I start.

Mine has 34k on it. I got a feeling the valves have been done once at 10k, showing the dealer service stamp. They sound OK to me. Not very quiet but not rattling.

There's a reason he's called @Sparky59
