k&n creates heat or not?????????

hey ppl who have installed k&n pls let me know are u guys having engine heat problem ; it wasnt on the tachometer but i could feel it on my feet

My question is CBR uses a close loop Fi system then O2 sensor should adjust the AFR ration according to AF ..? like when we install KnN in these kinda bikes ECU should adjust AFR ratio ..? Is it right..?

Yes the PGMFi will be in open loop at cold start and once the Lambda(O2) sensor reaches correct temperature will switch to closed loop...There is a limit to the variables to which the ECU can calculate from the memory look up table...If the amount of Air Filter Porosity or clogging goes beyond the range then the ECU cannot compensate for it.
Normally in stock form the air volume with stock filter is known and so program will be for a minimal variance of say 10% variation and not beyond,and the air filter clogging is a known phenomena and so the program will be more oriented towards compensating towards it.

I guess you have answered your own question when you said about is greed and the radiator.My guess is he has an Exhaust which gives the sound and is trying to bamboozle you with tech talk, knowing you are a bit less knowledgeable.Stay away from him, he is a Charlatan.
A SBK is multicylinder and produces a characteristic sound which cannot be made by the single cylinder engine.

You're right, its better to move on; Vishwas Ji's signature is more apt here

I don't know what to say on the PM

On sprockets...I'm still waiting; hopefully they don't put me into 45/90 days bucket

Can you actually remain consistent in what you say?

I am glad that you did not use olfacoception or gustaoception. In addition to ophthalmoception and audioception senses, you should also have used tactioception or better still you should have used the basic level of practical knowledge and judgment that we all need to help us live in a reasonable and safe way (defined by Cambridge dictionary as Common Sense)

First of all thanks for showing confidence in me. Secondly, K&N High Performance Lifetime Aftermarket Air Filters - Automotive and Motorcycle Air Filters claims that it Works with Original Equipment Manufacturer Vehicle Electronics. So shouldn't it compensate for the variation.

Secondly, doctor3003 had just installed the filter so there should not be filter clogging.
Most probably it was a subwoofer fitted under the seat loaded with sound files from NFS.

Hi doctor3003, don't mind but the mechanic is trying to con you, one cannot get the "Vroom" sound from a single cylinder CBR.. unfortunately that is a characteristic sound made by an inline 4 cylinder likes of say honda or yamaha. all his talks about getting sound by fitting dicor's air filter is utter nonsense!! you will end up ruining the bike.. or if its his bike then he is the culprit for the same. if you are looking to extract more performance from your bike then get in touch with reliable tuners like joel or buy stuff from yoshimura or two bros, power commander etc.

all in good faith.

cheers

Hello Doc, Please maintain peace and respect each other.

Your mech is talking utter nonsense. CBR 250 is a single cylinder engine (NOT A IN-LINE 4 CYLINDER ENGINE) Old CBZ is also the same Single cylinder 148cc single cylinder. What he did is he fitted his bike with a Freeflow exhaust without a Db controller and possibly he got some sort of a controller or something along with woofer/sound system which he possible integrated with his RPM. When he revvs machine throws out loud sound but the woofer/sound system also throws out digital sound waves causing it to create a dual effect and create a near resemblance to the charismatic sound of an IN-LINE 4.

Effects: His engine is fked up (Mostly a mechanics bike is always fked up). He also might have played with the muffler with his exhaust. His bike doesn't have a good power and would eventually fail even to muster and cruise at 60kmph. All he required was a good sound.

One Friendly Suggestion : Stay away from him else he would fkup your Cee Beee Aaaar.

Kindly Note: If you require an SBK sound you may buy the Yoshimura Inline-4 Exhaust which I had seen fitted on a Ninja and beleive me it was sounding too badly fked up SBK even if did. You can ask Vishwas/Tenhut for more details on that. Also I think if you require a SBK sound from your bike that badly, kindly sell off your bike and get a fullfledged SBK. If you need help you can definately contact me and I would be more than happy to help to a co-biker as I am only a pm/sms/call away.

Thank you for reading this.

+Million times!!! One cannot buy a donkey & wrap it up to sing like Cuckoo; it still brays

K&N's self proclaimed performance is doubtful.It had been proved that the K&N filter allows more dust and gums up quicker than a conventional paper filter.

Debunking the K&N Myth - Why OEM is Better : Nissan Articles

Regarding the PGMFi , I was trying to explain that the ECU is programmed to compensate ,more towards a restrictive air filter than a free flowing one ,since it is a common real life occurrence,under stock vehicle condition..doctor 3003 himself had said the engine heats up a lot after switching to K&N.
I respect knowledge from any and every source,which is how I had learnt....also from your posts.

PSR Ji & Vishwas Ji - There's something that we'll discuss over phone, as the subject is to raise controversies, on the myth of AM airfilters on C250R. Also I haven't personally verified the reports, but as an experiement by a friend of mine to share the results.

Obviously.. Not everyone has the same tolerance levels. Just suggested you to plug all gaps before you take the plunge to the consumer forum.

Congrats Sheel!!

Please decide on the venue and date of the dinner fast. I'm largely involved, as long as the dinner deal stands.

took a test ride of CBR 250 today. though had ridden it before belonging to one of our senior xbhpian.

the cone set on the test bike itself was sooo loose, i felt very bad. when i told the showroom guy about it, he said, "mech must have forgot to tighten it after fitting buzzer." now, whats that buzzer?? is it the same 'ting ting' sound which comes after you turn on any of the turn indicators?? if it is so, then that particular bike did not have it. then what it could be??

then the funny part is, he asked me "how can you say so confidently that the cone set is loose??". I replied "i own a Pulsar 220".

is that cone set problem so frequent in case of CBR as it is in case of P220 ???

Bro, do not waste your time and energy on this.

LOL....Vishwas sir i was asking about Working of Close Loop system ( or say how a close loop Fi should adjust AFR in case of After Market Air Filter ) and not about heat and other effects of KnN
