Re: Honda CBR 250R


engine was not flooded rather CBR is plagued with random shut down issues worldwide. while de-acceleration the ECU cuts/minimizes the fuel flow to extreme minimal to get more FE however sometimes when we press clutch in the same duration the ECU is not able to adjust with the revs falling rapidly and the engine dies.

the only solution i have also found is the same to pull the accelerator and then hit the starter.
it may also have to do with the air filter and mildly clogged injectors.
use system-g and also keep a check on air filter.
also if you are done 30k+ then time to check the spark plug too..

----consecutive posts auto-merged-----




its more to do with the air pressure and cooler air. when you are hitting 80-90 kmph the momentum and inertia is enough for not to drop the FE down unless the incline is more.
gaining 5000+ asl over 350+ km is negligible. had it been less than 100 km it would have made some difference.

Re: Honda CBR 250R

I had the same issue initially, I remember posting about it here too. But it has stopped for the past 4~5 months now. Never happened again.

This is what I did. Changed the fuel to shell v-power for 5~6 tank fulls. Now use normal for past couple of months. The other thing I did change is the airfilter as you have rightly pointed but airfilter change happened much later. One of the advantages of vpower is that it cleans the injectors, so I guess that what did it for me.

Re: Honda CBR 250R

On the leg from Bangalore - Chennai, the bike returns around 35kmpl. This is doing speeds of 100+

On the return leg, I'm in no hurry to get to bangalore and usually do a max of 95kmph, whereas the FE drops to 30. This is monitored not only in my CBR, but my AS200, a friend's KTM, and a diesel Swift as well. A drop of ~4kmpl is pretty substantial for a 5000+ asl incline spanning over 350kms... Btw, I didn't get your air pressure, cooler air point, can you elaborate a bit?

EDIT: Just understood the air pressure point. Yep, was thinking along the same lines!

Moved to the general thread so that you get more responses.

Re: Honda CBR 250R


i just meant to say air would be denser at sea level hence healthy amount of oxygen and engine would make power as expected with the change is air pressure ( thinner air as you increase the altitude) would also reduce the density of oxygen and the ECU will have to compensate for the same. this might be one of the reason of diffrent FE as i assume.

Re: The story so far.. My Honda CBR 250R

Assuming it hasn't had any accident damage/engine repairs and If every word of the above line is true, then that's a very fair price.

Re: Honda CBR 250R

The ironhorse99, this shut off was different, in that I was wasn't able to turn the bike on immediately. Other shut offs had the peculiar feature wherein the bike would start right back within a second of pressing the starter, albeit with unstable idle.

Re: Honda CBR 250R

I have faced this same situation once with my bike and it was scary as hell. I was doing the speeds of 140+ and all of a sudden engine died and i realized it after about 3 4 seconds when bike started a bit of fishtailing due to sudden braking generated by lifeless engine. I nearly missed a scooter by inches. I immediatly pulled in clutch and released it several times, nothing happened. Gave multiple starters, nothing happened. Somehow i managed to control the bike and brought it to halt on roadside since it was highway. All this happened within few seconds and was very scary experience for me.. After halting i cranked engine multiple times but it felt like fuel supply has been cut off. Switched ignition on/off and again cranked, nothing budged but as soon as I gave it a bit of throttle it started but picked up rpms very gradually and felt like it will die again if i fail to give more throttle.

From there i continued my journey without any problem but i avoided revving much all through the way.

Next day on inspection i found neutral light flickering on revving bike. When i contacted ASC they advised me to change the battery and suspected the battery only for that higway incident too.

Now it has been around an year since i changed battery and that problem never occured again. Though i faced random shutdowns a couple of times when i depressed clutch but nothing that sort of which i faced earlier.

Hope my experience will help u to some extent..
Sorry for being a bit long . 😝😌

Re: Honda CBR 250R

Hello all

I've been silent observer and follower of this thread and to be honest I've came to learn a lot about bikes through yoy guys. Now since I've been planning to buy a new bike for the last 2 years coz my 1st bike (hero honda ambition 2002 model) has started to show its age, I need help from you guys. Earlier I had my eyes on 150r but then for 35k more 250r has much more to offer. but my question is, is it right to go for 250r in early 2017 I mean this late coz it came out in 2011 since then there are no mechanical updates and as I'm looking to keep this bike for at least 7 years will spares availability an issue?

Re: Honda CBR 250R

After reading a few posts on such issues, my take on this is that it could be a bad ignition coil (or the wires from/to it) or the spark plug wire & boot.
If the ignition coil doesn't supply power to the spark plug, the plug will not fire which in turn obviously doesn't ignite the fuel and hence the shut down & starting trouble. In such a situation, when you thumb the starter, the fuel is being injected in to the cylinder but due to a missing spark, it is not being ignited and hence the cylinder ends up flooded with fuel due to the cranking.
Do a google to get some info on how to do a basic test on an ignition coil.

(from AliExpress Android)

Guys just wanted to know. Has anyone tried this, does this fit without any jugaad??

Re: Honda CBR 250R

Hey guys as I've posted earlier, I had a accident on my ceeber, its repaired, the SVC told me my front tyre was punctured n its weak, ok now I'm in a dillema, I can't just change my front tyre, rather change the set into a brand new set of Michelins. Coming to the front tyre I have a hardly used spare 100-80-17 tyre lying around, can, it won't cost me a rupee as I've said before I own a factory. I won't to know if the profile can be fitted on, I know it will affect my handling but to what extent? Note I need to change only if my front mrf gives way again, I just want to know what are the issues if I change to the 100-80-17 profile tyre. Rather buy a set all together and change in 4 months or soo.

second hand honda cbr250r ABS

Hi Guys,

This is my first post on this website, though I am being reading xbhp forums since as long ago as I can remember.
I am a bike enthusiast and I have been riding pulsar 220 f from past 3 years.
But now I got a deal from my friend and bought a Honda CBR250R ABS from him. He bought this bike in march 2016 and got only 2800 kms on the odo.
Along with the bike he also gave me the following accessories:

MT blade helmet
Sena 10s bluetooth
Riders jacket
Protection gloves
Knee pads
Saddle bag
K&n filter (already fitted in the bike)
And also, He has taken 4 years extended warranty in the bike. This whole deal costed me around 1.7 lakhs
I have been riding for long but I am still not a expert. I would like to know from my fellow experienced bikers if this was a fair deal or could I have gone for even less.
P.S.Will post the pics soon of my new CBR.

Thanks

Re: Honda CBR 250R

you get these for same price locally as well.. exact same price.
they are a direct fit for ABS model however for NON-ABS you would need to do some filing.which is not really difficult.

Re: Honda CBR 250R

I don't see a problem using the tire. But, here are a few "buts"

But with the lax of front end feedback. Your contact patch reduces, so the front end is easy to steer to an extent, and your grip levels when you lean would go for a toss (the infamous lean twitch) your ride height increases slightly. Increased sidewall provides good cushioning but if it's a bias ply you'd feel every single feedback on your bars, the ride does translate to a slightly bumpy ride. I hope you don't ride the ABS version.

I would suggest you use this tire as a temporary option, if handling and feedback are your priorities. Radials are comparatively heavier than bias ply, so that means slight reduction in unsprung weight slightly reduces.

Cheers!
