I have had my new M8 for about 2 weeks now. Every morning when I start it up it goes to "Fast Idle" like it is supposed to do. The problem is it revs up to 2300 rpms for about 6 seconds and then steps down to about 1200 rpm until it warms up and then drops down to 900-1000 rpm.

So, my question is what are the rest of you seeing on a cold start up?
2300 rpm on a cold engine just seems like way too much to me.

 

Mine fires up and idles at 1200 - 1400 for however long to warm up. Seems like it has behaved as you described a couple of times on real cold mornings, but I don't remember it going above 2k.

 

my 107 behaves similarly but don't recall over 2K either

 

mines does the same thing. I do not think that's abnormal, because once she warms up, she is in that 900 to 1000 rpm range for the rest of the day.

 

My 16 RG would jump to 2300 for just a few seconds, talked to the dealer they said it's ok. My 17 RG jumps to just about 2000 when it's cold? I think with a power vision that can be changed ( I might be wrong ). I'm going to have them do something about it when spring hits, I would prefer it not rev this high when cold. Somebody in this forum will have a cure.

 

I think the engineers actually think that the high quick rev at start helps to build oil pressure faster or something.
I've noticed that my new car and a lot of the new cars I've been in start and jump to like 3K for that reason. So maybe it's for that. I dunno.

 

My Road King runs up around 2 grand for a count of 3 or 4, then drops to around 1,200..Once fully warmed ( maybe a minute if its sitting) , 850 ( I have not had the 1,000 mile service yet for any software updates to be downloaded).

 

I think you can blame it on the EPA, they want that motorcycle engine to warm as quickly as possible. Starting at higher rpm like that gets the inside cylinder warmer so they get a cleaner burn started quickly.

 

My SGS couple of seconds at aprox. 2000 rpms, then around 1200 a minute later 850ish.

 

I just bought a 2018 Anniversary Heritage with the 114, it still has .7 miles on it because I am snowbound right now.
But I have let it idle long enough to get to full operating temperature today and it was +30 deg F.

It started at 2000 for a couple seconds, then dropped down to 1200, but it never went below 1200, except for momentary fluctuations that went from 1050 to 1250.

I am wondering if this is just a break-in period setting ???
