I just bought my slightly used 2012 honda cbr250r but never got a chance yet to test drive since I am still on the process of lowering it to about 2 inches. I am just wondering if model 2012 honda and up will still have issue like yours. I'm hoping, that this bike of mine will not give me so much problem. Anyway, just curious about it if anyone out there have had any issue yet about engine stall while downshifting or slowing down. Please advice.
so many variables, your on page 95..
odds are you wont have any problems..
seems correct no rev startup allowing it to drop to
1500rpm steady idle every time may, teach ecu this
idle speed point, which may, have some relevance..
also appropriate warm up in cold weather appears to
have some effect on ecu/catalyste function which may
have an effect on cold start ups..
appears that dirty fuel or ethanol fuel mix may effect
injectors and apparently will eventually deteriorate rubber
components of injectors and other engine parts, which if so
wouldnt help startup or general injector etc efficiency..
i use only, 91octane zero ethanol petrol..
[no hot cutouts since implementing start up mentioned above
and going to non ethanol 91 unleaded petrol]..
stress again tho that issues are raised here,
it isnt all cbr250r riders posting how trouble free
their bikes are, rather you get a distilled view of
those bikes which do seem to have some
ecu related or? cut out problem..
seems also that generally when there is a cut out problem
it seems according to reports from members that it tends
to fade away with miles and time..
just a personal observation; my last two hondas were 750/4's
which idled a bit higher generally, and a lot smoother..
this is a 250 single, and you do need to tailor your throttle
control to that engine size and type and its power delivery,
ie, basically, it doesnt recover so easily by carrying revs
when loaded to much compared to revs/power available..
so to start with, doesnt hurt to maintain idle speed
up a bit from 1500, say 2000, sitting at the lights etc,
prepared to clutch out for take off...
at least until you become familiar and sensitive
to the likes and preferences of this great little
honda single.. expect it to excel..
learn how to ride it well...
Just finished reading the topic. Seems there are many with the similar problems. Took the bike with 4000Kms on it. It was tipped over bike. 2nd servicing done on the day I took it just for peace of mind. Last Saturday I went for fun ride. The bike was around 40 kmph. I noticed LVM was not properly aligned, so clutched in and tried to downshift 3 to 2nd. I heard a large thud and the engine just died. I figured that it might be because I am not used to the new bike. Then yesterday when I was going to park it in the mall, same thing happena. Nobody has mentioned the THUD sound but I can hear it distinctively. I just can't seem to figure out what the problem is. :screwy::screwy::banghead:
BTW I ride mostly my 07 600RR Movistar.

when mine was cutting out hot i restarted it with the starter button,
as it cut out usually after rapid acell then decel incl clutch in so
took only a moment to fire up immediately on touch of button
then clutch out.. this was a reflex action initially, effective,
so used it next time and so on..
mine fires up first touch of he button every time anyway..
if you were in gear clutch in it would be easy to simply
dump the clutch, as in a clutch start, but firing it up
with starter then engaging clutch as revs rise
is smooth and virtually continuous..
tho surprising, it was also a pleasant surprise to observe
my brain and body immediately use the starter for
seamless continuation of the bikes momentum etc..
this would no doubt stem from years of riding
but would also flow from normal startups
esp when your focus is on that action..
ie, brain training...
as an update to my earlier reports on the stalling... after I got it back from the Honda dealer no stalls in 350+ kilometers (and I tried to reproduce of course ) no stalls anymore, kept similar Fuel cons. so happy camper now! they must have made the right change,still a pitty they didn't tell.
This has become a common thing in any vehicle, especially in European countries, make sure you practice every morning first heat engine 10 minutes before riding.
The other problem that, when stopped in gear 6 sudden without changing to a lower gear engine would be easy to stop even if you press the clucth, while electric power is still there ..... that is not a big problem because you must setup the ECU so that it gets more fuel and rpm will rise from 1.0 to 1.5
usually under the bottom of the 1.5 engine rpm would be easy to stop.
so you must find the right mechanical expert in this issue .... if you find the mechanical honda but not good at it, then your problem is not finished ....... hehehe
I rode as pillion today on my bike to see if the misfire and stalling occurs while rode by others. It's not the case. The bike didn't stall. But I noticed that the exhaust was sputtering while downshifting and engine braking being used. lost for words on how can it happen. Problem with FI ????
