Which brand and from where you procured it?

Is it cyclops one?

In case you have mentioned about it somewhere, link to that post will also b fine.

No , not the cyclops, Its too much out of budget for me.
Its a local acquire of this bulb (https://www.aliexpress.com/item/Osla...ceBeautifyAB=0)
Costed me 850INR
Will try to make a video of it soon.

Can you post a video of the indicators in action? I'm curious..

That is quite a budget friendly thing.

It will be interesting to see how it fares against expensive counterparts.

Waiting for your review buddy and pictures for comparing the illumination.

Re: Honda CBR 250R

An update to CBR fellows. Did a recent service from Honda ASVC at 28K on ODO. Some knocking noise was coming from engine and as suggested by [MENTION=51754]theironhorse99[/MENTION] it was a timing chain issue and indeed it was. As per the mechanic there were few more things which came out during service and he did the required changes accordingly.

1. Mechanic slightly blamed usage of Shell engine oil for early chain tensioner failure though he completely agreed that Motul/Shell is good but Honda throttle is best for CBR.

2. As per his inspection there is some slight damage on cam shaft sides and probably the reason behind this is viscosity of Shell 10w40 oil, I might mentioned the wrong engine part(cam shaft) here but he said 95% is in good shape and no need to worry, but the engine sound has changed a bit.

3. He changed tensioner, timing chain, chain glider and drained the engine oil as he had to open the clutch plates, as conveyed to me.

4. The spark plug was replaced as he said the gap has increased. And this time I came to know that spark plug is actually not only used for ignition but also for sparking the engine for some reasons continuously/with some interval. Also according to him spark plug should be replaced with a interval of 48K/2 years.

5. Coolant was changed as it was never changed in past 5 years.

I am attaching the bill below, this post is just to keep you updated about the servicing cost/status and further things of a 5 year old CBR.

Re: Honda CBR 250R

Hi,

i usually don't comment on the ownership thread but this seemed too good to let it pass!!

Hope my comments are not taken in the wrong way:

1. Mechanic slightly blamed usage of Shell engine oil for early chain tensioner failure though he completely agreed that Motul/Shell is good but Honda throttle is best for CBR.

ANS: I am sure the mechanic has a degree in chemical and mechanical engineering to differentiate between the oil composition and probably has another custom self-made standard for oil classification to be used in motorcycles. JASO (Japanese Automotive Standards Organisation) & API (American Petroleum Institute) must be idiots to certify Motul/Shell deemed compatible for any wet type clutch based motorcycles!

Timing chain elongation and auto tensioner going out of spec are known culprits in Honda CBR 250R, Honda CRF 230 and Hero- Honda ZMA/ZMR platform. Nothing to do with oil PERIOD!! 30 - 40k kms is usually when the timing chain goes out of spec. Of course hard throttling and acceleration put a lot of stress on the timing chain and may elongate it sooner than expected.

2. As per his inspection there is some slight damage on cam shaft sides and probably the reason behind this is viscosity of Shell 10w40 oil, I might mentioned the wrong engine part(cam shaft) here but he said 95% is in good shape and no need to worry, but the engine sound has changed a bit.

ANS: I am sure he knows the differentiation between 10W and 30/40 rating in an engine oil? The next time you visit the SVC ask him to bring the workshop manual and visit this particular page below and the raise questions about temperature Vs engine oil grade recommendation. Based on the ambient temperature the oil viscosity required for normal operation may change as the screen shot of service manual will suggest.

Also refer to this to understand what is 10 - W and 30/40 mean in an engine oil: https://en.wikipedia.org/wiki/Motor_oil

Once you have understood the grade differentiation and oil viscosity chart, ask him pertinent questions. I am sure you will get vague answers from your mechanic and probably bragging about the years of experience he has working on bikes but no concrete explanation to prove his point as to why 10W 40 is not good for your CBR!

Valve train camshaft lobes having scoring, galling or pitting marks may be due to natural wear and tear over due course of engine operation or metallurgy/production defects at the time of manufacturing. The service manual specifically mentions at what measurements one is supposed to replace/change them. If you are still concerned, change the cams intake cam will be Rs. 1,200/- and Exhaust cam will be 1,200/- (Taxes may be extra).

3. He changed tensioner, timing chain, chain glider and drained the engine oil as he had to open the clutch plates, as conveyed to me.

ANS: Normal procedure. posted in detail on: https://www.xbhp.com/talkies/general...ml#post1328232

4. The spark plug was replaced as he said the gap has increased. And this time I came to know that spark plug is actually not only used for ignition but also for sparking the engine for some reasons continuously/with some interval. Also according to him spark plug should be replaced with a interval of 48K/2 years.

ANS: Please try and go through the service manual. Available online for download with a little bit of search. Everything is mentioned there regarding periodic inspection and estimated timeline for inspection and replacement of components. If you go through it, you will learn a lot more about periodic maintenance and how to better take care of your motorcycle.

5. Coolant was changed as it was never changed in past 5 years.

ANS: Again as a motorcycle owner and member of xbhp you are expected to brush up on basics of motorcycle maintenance and refer to owner's manual if not the service manual in order to know what to change/replace/service at what interval. 5 years and no periodic replacement clearly makes your LC system susceptible to calcification and rust built up and potentially blocking the coolant flow path/galleys inside the engine.

I am attaching the bill below, this post is just to keep you updated about the servicing cost/status and further things of a 5 year old CBR.

Bill

In short, 90% mechanics in a service centre are only good at changing oil, oil filter and air filter. They don't know anything about the internal working of the engine. Most of them don't even know what torque specs are to be followed to tighten nuts and bolts let alone how to use the tools provided by Honda to service a CBR 250R. So don't follow their advise blindly, use logic, research and self analysis and only then come to a conclusion, or else you will end up at the wrong end of the tail.

Cheers,

Appreciate you attaching the bill. Though, Shell is a good oil, a thicker oil only means the lubrication is better, but the oil being thicker, the engine has to work a wee bit harder to lubricate during start up, but once the engine heats up, the difference if any is insignificant, unless the grade used differs by a large margin. Secondly, a spark plug continuously produces spark once the engine starts and an engine starts early morning only if the spark plug produces spark, so it's like a human heart, it always works when the engine is running. The spark plug produces spark only to combust the air fuel mixture and doesn't offer add-on services apart from this.

Nonetheless, it's advisable to replace the spark plugs every two years or the manufacturer recommended Kays on the ODO. The CBR uses NGK plugs which in itself is an very capable plug and has lengthy service interval.

Thirdly, one thing I did find in your bill is, "Cam Chain Tensioner CAMSHAFT COMP", the part number too seems weird, was this part changed, or was it billed twice. From your post, you've replaced, the pad, the chain and the CCT, but there is a mention of Camshaft Comp, which wasn't replaced, though interrogated by the mechanic to you. I hope though, the billing is clear.

Cheers!

Interesting... Did you tell the mechanic which oil you use before he blamed shell engine oil?

Re: Honda CBR 250R

I think the part you are mentioning is not a part but Labour Charges ..See in the next tabs it has timings mentioned as 1 hrs.

Re: Honda CBR 250R

Hi guys!
I am facing some issue with the speedo. Today while i was riding the speedo and the tacho went off suddenly. Now i have no indicators, no pilot lamps, no tail lamp. The meter doesn't show anything. The only things working are the fuel pump, starter , headlamp and horn. Engine does start up too. But there is nothing on the display! All the fuses are intact. Has this happened to anybody else? I am suspecting loose connection with the speedo and the ecm probably. Any help would be appreciated!

Unfortunately I cannot suggest anything other than double check the fuses. Do you water wash your bike frequently?
It could be a corrosion in the electrical contacts, however your bike is only 2-3 years old right?

Get the battery checked, similar symptoms happened for users whose battery was weak and about to die.

Yes! Its just 2 years old. I will double check on all fuses now. Will update after that

Re: Honda CBR 250R

Got it guys! Don't know how i missed the blown fuse lst time! Replaced it and everything came back on! Sigh! Sorry for the trouble guys. I had to double-check before posting. Anyways thanks a lot for suggestions buddies! Ride safe!
