Hi everyone,
My bike's ODO is now at 17779 Kms and it is due for 4th service.

Can anyone tell me what needs to be replaced at this point other than regular stuff like Oil and oil filter.
18K is a good time to check your chain and both sprockets, replace if worn out. If it is in good shape then get chain slack adjusted to specification. Buy a can of chain lube and lube it thoroughly.

Air filter replacement if clogged/dirty. Change spark plug if you haven't done it already.

Also the forks are like juggling when running into a pothole and handlebar are vibrating a lot. DO i need to replace fork oil.
These sounds like symptoms of worn out steering race bearings, if not worn out then I advise getting the race bearings greased. Also replacing the fork oil at 18K is a good practice, should help tighten up the front end.

Mileage is now running steady at 35 KMPL. But the gears are getting clunky and clutch is not smooth at all.
Mileage seems reasonable. An oil change should reduce the clunkiness, also ensure you get clutch play adjusted to proper specification, loose clutch adjustment leads to clunky shifts as clutch is not able to depress fully. Also a loose/dry chain can be suspect for this.

looking for suggestions. Thanks in advance.

It also would be helpful if you can enlist what parts/consumables have you replaced at previous service.

To sum up, consider this as a major service. Don't know how good Honda SVC is in your city, but its advisable to make a list of these things before going for service, and best if you can be present while work is being done on your bike so the technician doesn't take any shortcuts and say "work is done saarr..." Also ask for old parts to be returned if you are replacing anything.

Although it might not be possible to stay with the bike for service as they take one whole day or maybe two, to overhaul forks, race bearings, etc.

All the best!

Re: Honda CBR 250R

Has anyone seen new BS-IV CBR250 in any one of the Indian cities? I have been contacting dealer for few days now, but they are clueless. One confidently told me that it has been discontinued since last year when BS-IV became effective.

First of all many thanks for your reply..

So far only Air filter, Oil and oil filter are the only things that were changed.
I am considering to change Spark plug, Clutch cable, Throttle cable, fuel filter, fork overhaul, Brake pads on front (been 18K kms). For rear pads I can rely on P220 since it gave more life than expected (12K kms).

Chain sprocket - swingarm still has some gaps left, So I can reel them till next 6K at least.

Do not touch Spark plug. Manual says it needs a replacement only after 45k kms. And before changing any cables like clutch/throtlle get it checked by a genuine mechanic. A lot of time people just change things for peach of mind rather actual measurement of wear and tear.

A year back I used to do the same and the result was changing both the brake pads very early. When I posted the pic here people said it has only reduced to half or a bit more. Do not rely on the ASVC mechanic all the time blindly, they are there to rip you from all possible angle. If you do not understand ask any experienced person or at least post here.

Re: Honda CBR 250R

Any idea of the grade of fork oil they use at svcs? 20w fork oil gives a better front end feel I've heard.

Re: Honda CBR 250R

[MENTION=86472]sstherockz[/MENTION] - change clutch and throttle cables, they are cheap, and you cannot know their condition unless you remove them.

Spark plug change at 40k kms. NGK iridium plugs last really long.

Thanks [MENTION=58594]leech[/MENTION]
For the peace of mind I shall ask the SVC guys to inspect them anyway.
Thank you again.

Manishh, I've just been to the Honda ASS and they are clueless about the new CBR. It hasn't been dispatched yet here in Kerala. If you want one, you will have to wait a bit more. Maintenance wise, it's way easier than Dominar and FZ25.

Just changed the Chain sprocket at 47,536 kms on Odo after finishing a 1000 kms ride. Will post pictures of the old sprockets tomorrow. The chain will do another 10,000 kms easily, however I've changed the whole set.

They use 10w stock fork oil. For better front end feel, switch to Motul 20w,they stiffen the front end and give good feedback.

Oh! What a remarkable life for chain. Now a days I always suggest people to maintain their chain and have such long lifes. It's my bad that I didn't maintained it from day 1 and ended up with a replacement at 26K.

BTW. Does it Honda chain which lasted so long or any other brands like Bajaj (mentioned just it is most popular) can also give similar life if maintained properly ?

I'm the wrong guy to ask about Bajaj since I never owned one. The Bajaj bike with comparable torque figures is the RS200, it's up to the owners to report. The Duke 200 also has a chain sprocket lasting 45k, another guy on a 390 mentioned his chain lasted 30k kms. It's about how often you lube. The quality of the chain also plays an important part.

My chain maintenance wasn't perfect, the chain still has binding links that don't move freely compared to others. However, it hasn't stretched much, thus I feel it could last at least 60,000 kms. The front sprocket, however, started hooking, and the bike started making clanking noises when riding below 4000 rpm at 47.5k on the odo. I got it changed ASAP. Cost of labour was ₹660 in Uniride Honda Malapuram. I made sure the senior CBR expert was overseeing the replacement since it was the same service centre who got my bike stranded due to faulty spark plug replacement.

Old sprockets are pictured below:

I am impressed with the rear sprocket, it's absolutely astonishing to see the condition of the rear sprocket, given the amount of kays you've driven. Perhaps pressed with adamantium I presume.

Nonetheless, remarkable to see the rear sprocket in that condition, do keep your observations posted on how the new kit behaves.

Cheers!

Re: Honda CBR 250R

@VJ - it feels butter smooth with the new chain sprocket kit. Vibes reduced greatly at low rpm, the engine noise reduced as if it's doing less work now, the intermittent jerking when keeping stable, low throttle input is gone, and of course the clanking noise from the front sprocket is gone.

I'm no mechanical engineer, but it looks to me the tips of the teeth are made of different material than the rest of the sprockets. The tips are darker in color.

About the lubing interval, I had to leave my bike parked for 10 days due to a outstation trip, and I found on my return, the rear wheel wouldn't rotate freely. It would stop almost immediately after I spun it by hand. After I lubed the chain however, the rear wheel started moving freely again. This was with the old chain kit. I was surprised by the difference in just 10 days.

Thanks, for posting it here
Just for my knowledge, i think the sprockets are still in good condition , especially the rear one as VJ talked about it .
Front seems to be which has taken the load and is little turned out Directionally, but still good as teeths are not sharp or misshaped .
Correct If I am wrong , is it due to the chain condition you were facing issues ?
I am not very good at observing sprockets too.
Some more light on how to check worn out chain and sprocket will be helpful here.

For what I can understand it is always good to make the chain to be in tension while you ride , meaning changing gears at right RPM range and downshifting is also important , like revv matching techinique thats helps take out some load from the chain .
I personally think for CBR 250r the right time to upshift is above 5k rpm after 2nd gear .
And downshift below 5.5- 6k rpm .
I follow this and my motorcycle chain doesn't need adjustment for next 4-5k kms.
Just sharing my inputs

Re: Honda CBR 250R

[MENTION=81388]D.j[/MENTION] - my chain was pretty good, hadn't stretched much, only the rollers were loose and clinking while at low speeds. Don't know about Rev matching or upshifts, because I usually shift at 4-7k rpm depending on overtaking or cruising.
