Re: Honda CBR 150 R

Has anyone here replaced the air filter with an aftermarket filter and faced warranty issues?
Please reply.

Re: Honda CBR 150 R


filter wont void the warranty but whats the purpose of changing it ??

Re: Honda CBR 150 R

I was in doubt but thanks for confirming it.
As for the reason to change, it has increased performance by some extent.
Throttle response has improved greatly.

Re: Honda CBR 150 R

That's what they call a placebo effect! If you feel that throttle response has improved by a great extent, then the old filter must have been dirty.

Re: Honda CBR 150 R

Nor that svc checks it, But changing air filter Technically Voids the warranty .if the aftermarket filter is a simple duplicate of stock air filter and looks a like. Then go ahead and change it, otherwise, you have been warned.

Don't try to fix me, I'm broke so I don't work
So are you, but you're broke 'cause you don't work

Re: Honda CBR 150 R

its just the mind playing games.. old filter was dirty as mentioned if you moved on to a K&N.. you are letting more dust getting inside that precious engine.. be careful

Re: Honda CBR 150 R

Nope.
Had tried a new stock filter.
And then tried the pipercross one that I am using.
I could immediately feel the difference.
Also check out the pipercross fliter. Works well.

Re: Honda CBR 150 R

Which is the best oil for the 150r?
Has anyone switched from the stock oil to any other?

Re: Honda CBR 150 R

Hi guys,
A little OT question , but did not know where to post it so posting it here.
I have been riding R15 since last 3.5 yrs and as soon as CBR 150 R was launched, was exited and instead of celebrating people started verbal battles and started mentioning pros and cons of each bike.


one of which was an closed loop FI in CBR 150 R, as far as I know an closed loop uses the measurement of exhaust gases(using o2 sensor/Lambda sensor) for precise fueling. but there's a catch, a closed loop is used only in the initial RPM's i.e. below 60% of max RPM(according to ) since CBR has 11.5 k as cutoff, the closed loop will work until somewhere around 5-5.5 k, and post this it works as a regular open loop(found in R15)


Now here's my question, CBR being a short stroke has to revved hard to extract power (suggested by owners themselves, the shifting of gears has to be done post 5-5.5 k) so why is the CBR having a closed loop instead of open loop system when most of the time it will work post the required RPM of Closed Loop.


right now trying to learn about FI's.

P.S- I am not trying to start any vehicle battles here.


CHEERS

Re: Honda CBR 150 R


That is a sensible question.
Am not any technical guy., and I thought someone with more knowledge would be apt to answer this.

Well., none did.. so, let's discuss.!

I read that link of yours and it has explained a lot of details.
What I grabbed from that site is, there are a lot of factors or variables that are to be tuned in the functioning of the closed loop FI.
In that case, its not just theoretically definable , not at least to 100%.
Who knows how Honda has tuned it.

Okay, all said in defense :P..., that revving hard thing is true.
So, no use above 40% RPM.

But, think about cruising.
I think it comes into play there.
Cruising at 6-7k RPM all you need is just some few throttle degrees to be twisted (it is also in the equation, right?)
And, I am sure, it does some magic!

I've never believed when guys said they are getting 42kmpl on highways.
All I've quoted is a max of 35kmpl.
All this were till last month. When returning from Chennai-Blore on a midnight run.,
all I did was to hold the RPM at 6-7k RPM... & believe me this time,

I got ~40-44kmpl, for sure!

So, I think there is something coming into play, practically at some or other perfect conditions!
Not sure when or what they are to theoretically explain.

Re: Honda CBR 150 R


Thanks for your reply mate,
May be the thing you mentioned (here in bold) is one of the answers to my question, I revisited the website () and found this-
"Because of the time delay needed to get the air/fuel ratio cycling around stoichiometric, an accelerating engine can’t be effectively controlled in this way using Narrow Band sensors.This is why most Closed Loop systems operate only when the throttle opening is constant and the rate of RPM change is very low. ", well this tells the same thing which you mentioned above; may be when cruising and increasing the throttle at a constant rate the closed loop may work even a higher RPM's, leading to lesser emissions and higher performance.

Well, still these are just guesses and for the most part justify the answer to the question, but it would be good if someone with wholesome of knowledge on this topic would tell what exactly goes in there.
So how's your baby, is it getting along with you.

Re: Honda CBR 150 R

No problems.., Always a pleasure to discuss..!

My Baby? Nopes... My babe! and we both are enjoying the days!
Thanks for asking!

Re: Honda CBR 150 R

well..hello guys I am a Proud owner of Cbr 150R(orange) since October 2013. I guess its not too late to thank you guys here who helped me clear my confusion. Its been long and fun with my baby blade with the odometer at 6523km Coochie cooed her during Break in period taking it easy,however with few incidents where i couldn't help but rip her hard.After the Break in,did the servicing where the odometer read 750km. Due to some reason i didn't use honda specified 10w30 f.s mobil,rather used castrol power 1 racing(10w50).Engine was much smoother,soon after,followed by second service at around 3600 km. This time however i used motul 300v(10w40) which performed considerably better than my earlier mobil. Engine was much smoother with slick gear shift. It's not one of the usual bikes.One has to actually learn the way,weld properly with it,in order to extract the power buried within this bike.You have to be very involved with this beauty and then of course it will never let you down. A really marvelous engine,with a rev happy DOHC unit. One can,t help but Red line this machine each time someone rides it! and the fun factor is you won't even realize it till you see the tachometer. It red lines somewhere around 11,700-11,800 RPM with absolute craze after 8000 rpm. however it is somewhere in between 9000-11,700,where the engine goes berserk making all the power and let me tell you it's Addictive! One can't help but fall in love with the beauty with which it red lines . Till now the ownership has been hassle free. The service centre here in kolkata is quite good with really cooperative svc guys . Heating was never an issue even in the meanest traffic jams. till now i have achieved a top speed of 143kmph that too on 5th gear,post which shifting to 6th gears renders the bike relaxed.well it could have gone 2 to 3kms more had the road been a bit more longer . You can hit 135 on any given day and wind condition. mileage depends on how you handle the throttle. go gentle i.e below 7k rpm and it returns a good fuel economy of 40-42kmpl while rip it dead hard and it drops to 32-34kmpl while random thrust and normal riding gives you around 35-36kmpl. I have seen many people complaining about the low end torque,let me assure you guys its ample for city maneuver and pulls effortlessly with slight throttle(don't be so lazy). It's the way the bike is,low end simply amplifies the top end Rush! I have tried to coves most of the aspects..sorry if something has been left out cheers! Enjoy riding!

Re: Honda CBR 150 R

Changed Pilot lamps to warm white LEDs. No difference in output brightness though! Will swap with more powerful ones soon!!
