Re: Honda CBR 250R

10W???
The stock ones are 5w IIRC. The CBR might be able to handle the extra 10W though, but is a 10w really necessary for pilot lamps?
as [MENTION=51754]theironhorse99[/MENTION] pointed out, if the bulb doesn't come on the first time, its the polarity, so turn it around and it should work.
Why not get the same stuff from ebay india, you get a lot of these t10 5w leds for around Rs.200 :

Re: Honda CBR 250R

10w, because i commute a lot from bangalore to chennai and back. I plan to use them as DRL's in place of the headlight, reducing the load on the battery (Currently using stock HL, but planning to upgrade to philips racing vision, which burns at a higher temp, thereby reducing it's life, all as a measure for using the HL only when i have to.) Bought ones from ebay before, not very happy with the output, just got these to try them out. Fit them in, and they're pretty bright, even in day time! worth the wait.

Re: Honda CBR 250R

Considering your bike's mileage..

150 to 200 ML per every 500 kms in fact is higher than what a normal top normally is. In fact, unless the bike is ridden more than 600 to 1000 kays on a stretch, oil top ups on a healthy four stroke absolutely isn't necessary. I would suggest you to start off with cold check, check the engine oil level when the engine is cold after a spirited ride of more than 300 kays, if you find the oil level equally halved in the glass, after inspecting the bike on a flat surface, I don't think there is a need for apprehension.

Secondly, if you find the engine requiring top-ups on a constant basis per every 150 to 200 kms or the oil level dropping below the half mark, we are looking at potential valve stem oil seal failure or worse requiring upper engine work, that is piston/cylinder.

I would echo what I mentioned to my friend earlier, on the above post. Check the engine oil level after a spirited ride, if all seems well within the mark, then I don't think you should have any problems. Also CBR shows the perfect oil level when heated up, say the first few KMS. Just some times, when inspecting the next day, the oil seems "stuck" inside. Once the oil heats up and starts flowing, you have your perfect level.

Takes a little practice checking oil level, but you'll get used to it.

Re: Honda CBR 250R

My bike has slight oil leak on the top of the engine, and requires oil top up of around 150 ml every 2k kms.

Re: Honda CBR 250R

sounds ok but still should not be needed. we have a upper and lower limit. as far as you are in those limits we are good.


these arent actually 3 watts but as bright as 10Watts.

PM me with your address. i will ship you some real good stuff. whatsapp me.
got some real bright good ones.


i have never topped up my engine oil in last 50k km. not even on gruelling ladakh trip. not in hot roasted rides of summer and ideally its not needed for a new gen 4 stroke engine oil. however some rare cases if you are doing sustained high speed long runs it might be needed by a few ml. as far as you are in the tolerance window ( up and down limit) you are good. if its going below it you should start reverse engg on where is the engine oil going.

however a lot can be dependent on what engine oil you used and what was the usage.

Re: Honda CBR 250R

Any CBR 250 owners in Ooty at present? Im planning a trip to Ooty next month.

Re: Honda CBR 250R

@B7ACKTHORN sir is there. please check for his availibilty.

riding from where to where ?

Re: Honda CBR 250R

Malapuram district, Kerala to Ooty. Yes, it would be a pleasure to meet senior riders.

Re: Honda CBR 250R

Thanks for the sharing your valuable knowledge. Actually in the last 6000kms she almost did 5500kms on highway. A min of ~200kms stretch for a single trip. I had been frequently(once in a week) riding to & fro Theni-Trichy which is exactly 180 kms one way. Mean time also rode to chennai, munnar, coimbatore & madurai.

The only prob as of now is her timing chain pad set is in bad state & needs a change. I'm waiting for the spare from the local Honda dealer. Will that be any cause for the oil level dropping?

If not I think it's time to let her go and find a new love. 🤔

Re: Honda CBR 250R

[MENTION=39214]B7ACKTHORN[/MENTION] professor has relocated to our very own Hyderabad a couple of months ago! Should meet up with him sometime, he was kind enough to come and meet me while i was in ooty
Anyway [MENTION=58594]leech[/MENTION] check with him if he's going to be back in ooty when you visit or for any information related to ooty.

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

A cbr in good shape doesn't consume that much oil even when you ride at high speeds(i.e. 90-120kmph) on a highway. [MENTION=51754]theironhorse99[/MENTION] rides fast and i've been on a few long trips with him, no oil consumption.. neither on his cbr or my d200. And folks who ride with me know that I am kind of the duracell bunny on a d200
In your case I guess its the age of the bike and normal wear n tear of either the valve stem seals or the block/piston rings. If you are using the 10w30 oil, I suggest you move up to 10w40 or a 20w40 FS oil now (from a brand like Shell or Motul).

Re: Honda CBR 250R

In fact, I just landed today morning to Hyderabad after a week long vacation to Ooty. Let me know if you require any stay assistance, I can help you out.

Aman, kindly please don't call me sir. I am no better than you guys. Vijay it is.

Nopes. AFAIK, timing chain won't cause a drop in oil level. It's either the symptoms of a slowly failing stem seals/piston rings or valve cover leak. Also do keep a tab on your oil filter cover. The thing sneaks in real nice under the cowl, most leaks happen at the bottom of the filter cover, due to loose bolt, improper gasket, and can cause reduced oil level.

Professor? Who? Where? You never fail to impress me, s1d, as I said, just no better than you guys are.

Shall try to catch up with you guys this weekend!

We have a lot to talk.

Cheers!

Re: Honda CBR 250R

I have done only one high speed run till now with speeds over 130kmph for 60kms and i kept the bike at 160kmph for a good 10secs once, that it. Rest are all below 110kmph. I don't notice any soot in the exhaust as well. Now am guessing that naresh might not have filled to the oil to the upper limit. I wasn't around when he filled the engine oil and on top of it, i have checked the oil level when it is on paddock. I just checked the oil level (engine cool) and this is what i see

I seem to have over filled



I will keep an eye on level and see if it goes down as i clock some more kms.

Re: Honda CBR 250R

Yeah. Thank you. I'll try changing the oil. But I personally won't be fully satisfied because I feel Honda's throttle makes sense for a butter smooth engine to me. If it's the case with valve stem seals or the block/piston rings as you people suggest then I think Ill let her go. Let's see.. 😑

WRT timing chain I thought the same too. I'll check for oil filter cover leakage thoroughly once again. Let's see what's happening. I'll keep it posted here. Thanks VJ. ☺️

Re: Honda CBR 250R

It indeed is overfilled. On a you can remove a couple of hundred MLs off the bike when the bike is cold, make sure the glass is equally halved. If you are continuing with any further experiments , do so with the oil level centered, so that gives you an idea.


Do keep a tab on the oil level for a month, if you observe she requiring frequent top ups, then we can confirm that there is indeed combustion of oil or a potential leak/weep.

Cheers!

Re: Honda CBR 250R

Guys I keep facing this issue of air dropping in my tyres, especially the front, tho there isn't any punctures or leaks, can like alloys cause this?30 on the front and 40 on the rear because I filled yesterday air, both my front and back of my bike had excess air despite not being used for 3 days n not filled over a few weeks, makes no sense...can like slight damage to alloy cause this, my alloy is fine as after the accident got it checked , tho speculated at first.
