2019 cold idle

Morning all,
Does anyone else find their CR (mine's a 2019) idles very high and responds a bit "odd" when cold? I'm used to FI bikes idling near enough at their warm idle speed when started, but with CR it's like an old carb bike with the choke on, the revs climb pretty much straight away to about 3k and stay there for a good few minutes at least. Throttle response is terrible at this point (I'm guessing because the bottom portion of the control is irrelevant if it's supplying enough fuel to get to 3k rpm). Once warmed it's metronomic and idles at 1200rpm perfectly.
Is this normal? A V4 quirks?
Cheers
Rob

The VFR800s have always been a little hesitant when cold, especially at low revs. There are things you can do to it that may make marginal differences.
The idle issue doesn't sound right to me though - has it been recently serviced? Have you had it checked by your dealer? It's still under warranty so that would be my first port of call.
98 VFR800 - 130,000 miles, 08 VFR800 - 76,000 miles, 15 VFR800X - 44,000 miles (all sold)
14 VFR1200 - 20,000 miles
18 VFR800X - 16,000 miles
01 VFR800 Fi-1 - 9000 miles

Hi Rob,
I can't speak for 2019, mines a 2016 but I can say that mine is 1200 rpm on normal start, but on these recently colder mornings has jumped to around 2k rpm and sits there until warmed up (2-3 bar on the oil temp gauge).
In either case though the bike doesnt like being opened up at all until it considers itself warm.
3k seems a little high though!

Mine (2017) does exactly the same as yours SX. When cold and unlike how silky smooth it is 99.9% of the time it's an absolute dog to ride if not warmed up a bit 1st.

So I went outside to double check and it was cold idling (about 4 degrees in the garage and the bike hasn't been started since Saturday) at about 1800-2000rpm. I could have sworn it was higher than that last weekend, but maybe not - I'm still getting used to the digital tacho! I'll keep an eye on it either way - thanks for the feedback.

It's the stepper on the ecu allowing the engine to reach opperating temperature on idle. Just normal... sort of like using the choke to warm up old carb bikes to let the engine to get to opperating temp before you rev the guts out of it & start stuffing valves. I don't move any of my efi bikes until the idle revs start to drop on cold starts even then I baby it a bit for a few kms before I go Jeckle & Hyde.
Edit: knock your idle down on the adjustment screw when hot to 1000 if its still revving hard on warm up it could be tps adjustment @ the throttle.
Edit again .. sorry. If TPS adjustment required will be also noticed by jerking/stalling issiues

I have had a similar problem and it usually results in the EMS light coming on (once when I was in the middle of Normandy!). I have taken it to the dealers twice to be told it is “no fault found”. I have also posted a reply about this on another mail on this in the general chat area. There is something not right but, in other respects I love the bike so I live with it.
