Re: Honda CBR 250R

accident damage for 1.4 is a joke. just stay away from it.
ideally you cannot retrofit as its too expensive making in parts from outside.

i will check with a friend of mine who might sell his CBR.

Re: Honda CBR 250R

This mostly happens after washing a bike, as spark plug and cap get wet let it dry for few minutes and then crank again.

Re: Honda CBR 250R

approximately 3000 for service and parts seperately. Let me know if you need the cost of any specific part, I'll try to get it from one of the invoices.

So friends, it's been almost a week since I'm unable to find a spark plug cap in Mumbai. Since I did not want my bike to be lying around at the FNG garage for such a long time, on my insistence the FNG mech did a local jugaad of fitting a KTM spark plug after some modifications. (I know this was a bad risk) He also adjusted the idle RPM to address my stalling issue at idle RPM, though the FNG mechanic says there was an electrical short on the throttle body which was causing the erratic RPM which is fixed now.

Well, the bike worked well for whole of 20 kms and now I my RPM idles at 3k rpm. Now I'm just waiting for the spark plug cap to arrive post which I'll have a thorough check done at Official Honda SVC

Has any one tried manually adjusting the rpm on throttle body?

Re: Honda CBR 250R

The manual of the CBR states to not adjust the idle RPM screw, which undescores the high probability for TPS sensor malfunction. The TPS is the one which helps the ECU know how much one is opening the throttle. Basically your idle is controlled by the IACV which sits on throttle body. If the IACV is faulty or malfunctioning, you'd have erratic RPMs. And if you've increased the idle from the idle screw and once the engine heats up, and the IACV starts works intermittently, your idle will go above 3.5k and sometimes behave normal.

The term electrical is what concerns me. Though the chances of a faulty sensor can't be ruled out, shorting is highly impossible unless the connector wires are frayed. But, I'd suggest you remove your throttle body, give it a through clean with a throttle body cleaner and see how it fares, and try restoring the idle back to 1.5k post throttle body cleaning.

Keep your observations posted.

Cheers!

Re: Honda CBR 250R

1488 is the right idling rpm

Re: Honda CBR 250R

Hi. Try calling up a shop called expo spares in Lamington Road. They have most honda cbr parts.

Re: Honda CBR 250R

Hey guys

I'm planning to get a metal piece welded under the side stand rest to raise its height ( 5mm to 1 cm ) to address the issue of too much side tilt and broaden the base of side stand rest a bit of my cbr.

Is there any chance of it messing up the bike electronics or any other stuff in the bike?

Re: Honda CBR 250R

If you mean welding a piece to the base of the stand, then nothing to worry. No electronics will be affected, as there is none connected to it. Secondly, before welding make sure, that one of the bike's battery terminals are removed, stand is in its retracted position so that the extra piece doesn't foul with anything nearby. If everything's okay, then go ahead.

Cheers!

Re: Honda CBR 250R

That's what the mechanic actually did, when the bike wasn't able to idle well the mech suspected a problem with the throttle body which we got thoroughly cleaned with a throttle body cleaner. See the pic below for how the throttle body looked before we started cleaning. Forgot to click a pic of cleaned throttle body. I also sprayed all connectors on the throttle body and bike with WD-40 generously while at it




Unfortunately, that did not not fix the problem and then I suggested to check the spark plug which was replaced during service. This is when the spark plug cap was broken and the dilemma continues.

I am just waiting for the spark plug cap to arrive at a Honda SVC until which I'm not taking any chances running on the KTM spark plug. Hopefully I should get this sorted this week

I called them, they don't have it unfortunately or they refused to try hard and find it for me over call which is expected for most Telecon inquiries. But thanks, this is going to be handy for other CBR spares

I don't think it'll hamper your electronics in any way, but take precautions with the battery as B7ACKTHORN suggested.

On a side note, why don't you rather get a sidestand pad ? something like this is purpose built and will meet both your requirements bothttps://www.aliexpress.com/i/32852766944.html

Re: Honda CBR 250R

My bikes done over 63k kms and had lost power and FE over some time.
SVC opened the head and says I need a new piston kit. Some pics attached.

My question is will it be ok with just the piston and liner or do I need the block too like the svc insists?

Re: Honda CBR 250R

Whenever you're replacing a bore piston kit, try to replace the cylinder/piston kit as a whole, than installing a new single item alone or the liner alone. I'd also recommend you to check your valve stem oil seals, shim clearances, and replace your spark plug and clean your throttle body while you do this half engine job.

Re: Honda CBR 250R

Thanks, the valve seats and guides are also on the list.

Re: Honda CBR 250R

Hello everyone!

My bike's (non abs) rear brake pads have worn out. I can see a very thin portion remaining. I asked the Honda dealers here in my area and none of them have the part in stock.
I read somewhere that the brake discs of the Pulsar 220 are a direct fit to the CBR's.

Should I go ahead with Pulsar brake pads or wait for the Honda brakepads to stock?

Thanks in advance! [emoji3577]

Re: Honda CBR 250R

The 220 pads were said to be a direct fit. But make sure you get the model right. If your rear callipers are Bybre make then make sure you get the pads for the 220 series which came with bybre callipers.


Cheers

Re: Honda CBR 250R

Yes, they are a direct swap for the rear. Secondly, before installation make sure, the Pulsar pads are glazed mildly with sandpaper and then installed.

Cheers!
