Re: Honda CBR 250R

The SVC is just trying to loot you. Under free service, they will say ' oh no change is required' but go there for paid service, they will happily order you to change everything. This is called business. Ulloo banaoing. Just change things as per manual. Don't forget to re read the manual for time to time.

What are the symptoms of heating in your bike? Temp gauge going above 3 bars is generally a reliable sign of overheating. Check if the radiator fan is working too.

Re: Honda CBR 250R

Thx Bro. It seems have to find a new mechanic for the service.

Re: Honda CBR 250R

The temp bar never went above 3 bar. But bike heats more than usual, even rides of 10 mins n I can feel the heat.
Radiator fan runs generally when I have to ride in city traffic.

Re: Honda CBR 250R

Then don't worry about it. Just check the coolant level and top up if necessary.

Re: Honda CBR 250R

Hi everyone,
A small yet strange incident to share with you all.
Rode to hills near Mumbai with a pillion last weekend and experienced a very sudden loss of power on a certain incline which wasn’t more than 10-20 degrees steep. Bike wasn’t able to gain much momentum even with downshifts and I felt the same restriction as you would feel on a carb bike when riding to high altitudes except this wasn’t that high. After negotiating the 100-200 meters of incline at a gradual pace with some hiccups due to frantic gear changes, I stopped at a level road to check for issues. Revved the bike in neutral till 5-6 k and seemed all okay. Got down to inspect for leakages and then the bike died on me while putting it on the side stand. Restarted with a single crank and died down again in a few seconds without any inputs from my end. This happened 2-3 times as the engine killed off itself with slight or no input from my end and the RPM meter rolled from 0 to top RPM every time the engine died. Maybe this was due to the slight incline while the bike was on the side stand. Not exactly same but I had faced bike console not lighting up on two previous occasions when the bike was parked and it started up as soon as I started getting the bike upright.

I cautiously rode some 100+ kms after this incident at 10 pm in the night but luckily the bike did not die or lose power again. Any thoughts what could be the issue?
A cause that I can possibly associate to this is a day or two before this incident, I accidentally emptied the whole tank and luckily sputtered to the fuel station just in time to fuel up for the full quota of 13+ liters. Since then, I felt slightly jerky acceleration all the times but not something to be overly concerning.

I don’t want to tinker around unnecessarily but my mind says to get the throttle body & fuel pump operation inspected at Honda ASC. Your suggestions please

EDIT:
Bike is 2012 ABS run 31k kms engine oil changed to Motul FS & fluids checked at 30k kms

Re: Honda CBR 250R

Was your fuel level low when you climbed up the hill?

Re: Honda CBR 250R

No bro, I was at 3-4 bars. Good for another 150+ kms. But you make a good point, the fuel may be the culprit here as I tanked up at a remote Reliance petrol pump primarily catering only to trucks. That may explain the jerk on acceleration but can it also lead to engine dying off at standstill?

Re: Honda CBR 250R

CBR has got a problem of engine shut off randomly. You mentioned, you immediately started the bike again, but it stalled again right? The engine shut off on CBR is of two types :

1. Flooded engine. Engine dies, won't start until you give half throttle and start.

2. Low rpm stall. Engine dies, will start immediately and then stall immediately. Trick is to turn the key off and on, then start the bike again.


Ride the bike again before going to SVC and reporting any issues. They are like a certain corporate hospital, where you go in with cold, and come out after CT scan of your brain. If you butt starts itching, they will do colonoscopy and then only let you go.

Re: Honda CBR 250R

Yup, I was panicked a bit and kept starting the engine within seconds of it dying. Engine was adequately heated up when this happened and RPM was well set so I may not be able to relate so well to reason 2.
I had heard about engine flooding issue but the engine very well started up every time and kept dying after a while. Some basic search on google and forum suggests engine flooding usually happens with long duration of parking which was not the case either.

Yeah I'm riding the bike in Mumbai traffic since few days and no such symptoms apart from the mild jerks now & then along with assorted sounds from chain cam tensioner and rattling at 5k RPMs (this is not an issue as per Honda CBR mechanics). Thanks for the suggestions, I'll wait and watch till i actually need a CT scan

Re: Honda CBR 250R

From my experience with the unicorn 160/Hornet, Honda mineral oil was good enough, but didn't last long. After a total 1500kms, my engine was heating up much more than usual, gear shifts clunky and engine felt quite rough. That was good enough reason to change the oil.

I changed the oil, it's fully black (this is ok) and it's like water (after a small idle warmup of 5 minutes). Changing the oil to fresh Honda mineral, it was back to normal.

I rode the bike in the dusty traffic infested heat island called Bangalore.

I changed mineral oil every 1500-2000kms. Not more. I just couldn't take the roughness, clunky gearshifts and the heat.

Mineral oil is good enough for daily use though.

EDIT - My Suzuki gixxer also behaves the same, also the throttle response becomes lethargic and engine becomes extra noisy.

EDIT 2 - other than the oil, on both the bikes the air filter becomes very dirty by 6000-7000kms itself.

Re: Honda CBR 250R

[MENTION=80486]Shashank K R[/MENTION] - Nothing wrong in changing oil early. But it's wasteful for environment as well as pocket. I top up the oil every 1k kms around 50 ml, which makes the engine smooth again. Currently my bike has done 6100 kms on Honda 10w30. Have to change it soon. Will surely update the thread if my engine blows up.

Re: Honda CBR 250R

Engine definitely won't blow up.

The oil levels were correct in my bike. It's just that some people don't have much tolerance for the roughness/clunky gearshifts etc. I'm one of them.

Overfilling only caused more agony (leaking head/timing chain sprocket cover, etc). There was no requirement of topping up in my bike though.

Once though, I have pushed the bike on mineral oil for around 3500kms, and it felt awful to ride.

For me it looks like Honda hasn't kept the Indian temperatures/air quality etc. in mind while recommending the oil change interval.

I'd rather spend money on my bike to remain happy with it than to keep riding the bike grumbling about its problems. As for the environment, our vehicles are culprits themselves.

This is only my opinion though, it won't matter to most the people out there. To each his own.

I'm done with OT.

Re: Honda CBR 250R

Hello CBR gurus,
I am due on my 3rd servicing and had a few queries. (Bike is 2017 March Model run 11500KM)

1: There is weird kind of a knocking noise coming from the engine area near the radiator when ever I try to accelerate hard. The problem is not there in lower gears or lower rpms' , it comes out only after the 4th gear and 4000rpm . Initially I thought it is the infamous shims issue, but I saw some videos on you tube and the noise is completely different that I am facing . Also the noise is not there when I rev the bike to any rpm in neutral or leave it in idle, and it is more prominent if there is a pillion on (under more payload) . Any pointers on this would be great .

2: I am planning to replace my fork oil with motul 20W grade fork oil. And have found mixed suggestions on different forums. Some say we should stick to the 331ml per fork , some say we should put in 350ml per fork and some say putting 350ml of 20W grade oil might put pressure on the seals and they might go burst on sudden speed breaker encounters. What should be the proper quantity per fork ? Also any pointers on sourcing the same from any vendors in Bangalore? I don't want to order on amazon since the reviews say broken seal and duplicate things are received.

3: I am also facing issue with the cone set and it gets loose every 3k kms or so and requires tightening and adjustment . Was wondering if it is common issue or am I plain unlucky? (I ride in a quite safe and sane manner)

4: Also this question is a trivial one , but I was planning on changing my tires to Pirelli Diablo Roso2 (or Sport Demons depending on availability) and I still have around 8-10k left on my stock MRF's . Main reason I wanted to change tires was the wobbly handling and the soft front end , was hopping that the change in tire would change that . But will the fork oil change suffice and decrease the wobbliness??

Any other general pointers would be appreciated.
Thanks..

Re: Honda CBR 250R

The knocking metal like sound I face too, when accelerating uphill from 3-4k rpm. No idea what causes it, however I try to avoid it by changing gears at 6k rpm uphill and with pillion.

How do you know the coneset is loose?
