Anyone having this problem ?

[luke scott]

My mate has a new S1000 XR. When starting from cold the revs sometimes go to 2,000 plus and in gear the bike will pull up a ramp from his basement. BMW are saying there's no fault showing. Is this a known issue ?

My Ten 1 would often rev quite high when starting from cold - cant recall the actual numbers - but it soon calmed down
I reckon it is a thing with in line 4s or 4s in general as my Ducati Streetfighter is the same and reeves high for a few seconds on start up.

2k isnt high revs for a XR if you think about it in relation to how they spin up to 11K +

Same with the Z900rs I had, well documented on the bike forum

Think it's to get the cat hot quickly

My 22plate xr does the same,not a fault they all do it.

do you all have stepper motors , controlling your t/over speed ?

Guzzi's ... cold temperature , rpm's high on startup , and falls away as it warms .
pull up at lights with clutch in , in gear rpm stays at 1800 , and slowly drops to 1200 .

at lights in neutral , pull clutch , select gear rpm will rise to 1400 ish , when air temp is low.

No stepper motors ecu controlled throttle bodies ,it can be programmed out using bren tune software but it doesn't bother me tbh

Even my Interceptor starts high before idling normally after a short wait ️

I'd say this is normal. Having only owned in line jap 4s (until buying a 20 year old GS 1150 recently), the efi ones I've had all start at highish revs 1800-2000 for couple of minutes ( depends on outside temps) then settles to normal tickover. It's the same as choking a carb bike, revs rise until choke backed off.

On modern bikes the ECU controls it.

This is a Euro5 "feature" as the cat has to get up to temperature in a certain time so you get a fast tick over when cold. I had this removed on mine when I flashed it (Bren Tune) as it got on my nerves
