Re: Honda CBR 250R

What about tvs tru4 fully synthetic

Re: Honda CBR 250R

Stick to honda engine oil in this case

Will wait for the [MENTION=32286]psr[/MENTION] ji.

Re: Honda CBR 250R

Once used fully synthetic oil in brother's hero hunk on first service and the result was a head cover gasket leak in the next 500kms. Oil used was shell. Small engines doesn't require fully synthetic that is what i feel. Happy with 10w30 oil made by tide water india(veedol).

Re: Honda CBR 250R

Thats exactly what happened in my case with ZMR and apart from that Clutch slipping! Was quite annoying

Re: Honda CBR 250R

You "technically" have a higher chance of blowing a seal with 20W oil compared to the 10W oil but I'm yet to experience or hear of anyone blowing a seal using 20W instead of 10W, so 15W wont make much of a difference when it comes to practical applications.

If its any consolation my CT100B is recommended to run on 10W30 engine oil but as you can see I run on 20W50, simply because I get a discount going for a large can and my other motorcycle requires 50 grade oil;



I've ridden for close to 2 weeks at redline speeds i.e highway speeds for the rest for 500~900 km's a day and I'm yet to blow a seal at over 22,000 km's on the odometer.

But then again it is your motorcycle so I'd suggest you do enough research on the matter and go with what puts your mind at ease.

Here's a website PSR sir shared a few years ago, it is very informative. I would suggest that you start from here;

Dan's Motorcycle " 4-Stroke Oil "

Re: Honda CBR 250R

Actually its a design fault in recent honda engines, having higher compression ratio in an aircooled engine and due to inadequate cooling, we are facing lots of refinement issue. Whenever i visit honda svc all hornet and xblade owners complain about engine heating. CBR 250r is the safest bike, low compression ratio for an liquid cooled engine + good liquid cooling = peace of mind [emoji3]

Re: Honda CBR 250R

Wow you've made an exel chart for keeping record of engine oil. You're a pakka automobile enthusiast [emoji16][emoji16]

Re: Honda CBR 250R

You worry too much, my Discover 100 4G ran a near similar compression as the Honda Hornet, used to commute to and fro from hostel on a bi-weekly basis for the weekends covering 700~800 km's a day one way, other than the frequent tube blasts due to carrying luggage at rear I've never faced any mechanical issues except for a hydrolock which again was an error of judgement on my part.

So get a decent helmet to zone out the noise and focus more on covering more miles, though it might not make much sense a helmet can make a world of difference, using a ISI helmet my P220 is unrideable owing to part carelessness and part riding pattern but the moment I slip on a ECE cert. helmet the fairing and engine rattles don't bother me at all.

Ride Safe and Far.

EDIT:

Heating on any air cooled motorcycle is normal and it would not be ideal to compare it with a LC as the CBR250R. As long as there is no metal residue in the strainer, and you change oil at 2k intervals and there is no visible smoke from the exhaust, all is well. Ignore the rest and keep riding.

Crappy memory mate, made a lot of questionable life choices hence I cant remember my next oil change neither for love nor for money and it doesn't get any better owning two motorcycles and maintaining a few other vehicles for family.

Re: Honda CBR 250R

Thanks for the reply . Now iam feeling relaxed

Re: Honda CBR 250R

I opine it'll do even better considering the traffic and the high revving reqd,for is over square nature, radiator position that is tucked little inside the fairing. Such designs get thorough air blast while on tracks or long stretches.
Also, a good shift rpm seems to be close to 5k or more, may be a little less for traffic . Eventually, I have to spin it till that, without which the engine doesn't feel ready for the next gear. This gets even sure with a pillion rider. When I strictly follow this pattern, the engine sound feels nicer after the ride than when ridden with early shifts- my experience.
Anyways, this heats up a bit more and an extra radiator should do more good. Too much of a story.. sorry..

Re: Honda CBR 250R

As I said, it is a gradual cumulative effect which one may not notice during his ownership period. it requires a lot of time and patience to evaluate. 50 or 60 k is not enough, probably one may not be using a bike that long. But, technically speaking, there will be a difference in engine longevity.
The same Honda manual had 10w30 and 40 grades. The manual available now has only w30.
These days a 10 w 30 oil performs equal to a w40 oil. Concept of thicker oils making the engine smoother etc is outdated as per a source from an oil company. The trend now is towards thinner oils , at the same maintaining film strength at high temperatures. The trend now is making thinner oils and at the same time maintaining film strength at high temperature..

Re: Honda CBR 250R

And where do you plan to mount your extra radiator?

Re: Honda CBR 250R

Are there other things that could be cross utilized from other bikes? I mean like pads, brake discs, suspension( rear). Mine is a non abs. My friend suggested a mechanical type abs which can be fitted to a non abs bike.
Would also be grateful for any tips and tricks other than those requested above.

Re: Honda CBR 250R

Plan is in its crude state now.. need to think well and step in. It won't be a blunt add-on, but something good and mus be able to reverse to stock without much trouble.
Will post as things materialize.
Would you recommend using gear oil 90 as a chain lube?
If not,which chain lube is good what is the lube interval?
