Update:

AFR now 3 turns. Cold starts seems to be a lot better. Comes to life in the first crank itself. Also heat is reduced. Also a smoother ride ( maybe a feeling). But a slight problem. The bike is bogging during throttle opening often. Well I believe because of Air filter ( 11k kms clocked on stock filter). Will be changing to ZEN mpfi filter if feasible.

But one doubt regarding Zen mpfi filter. On stock filter there is a metal mesh behind the filter. Will I be able to retain that metal mesh when changing to Zen filter?. Actually is it necessary to retain the metal mesh? .

Th stock filter is always better than the Zen mpfi filter. I got it changed recently, its just 205 rs at hh. see the old and new pics.

help...

woow ... i was continuously ... reading the posts made by experience ppl and the questioned asked by other fellow Karizma R owners.

My bike has done 16 K KM in 1 yr. 6 months ... few months back i have changed my front disk pad from authorized HH service center (in vikhroli) got it for rs 1200 as my old one worn out completely,actually was damaging my disk plate. After installing new one ... noise is coming from the pads ... as if the break pad is in continuous contact wd plates ... thought its normal as have installed new but after riding almost more the 500 km the problem is not yet solved. i seriously donno what to do ...

Secondly i also asked after the spark plug , air filters etc .. from HH service center , they told me they are not allowed to change those.
So please tell me good mechanic shop from where i can get those stuff fitted also i ll service my bike from the same shop if i find the work good ...
i stay in kanjumarg ...

Here is the plug

Zen MPFi filter was used by me since for more than 3 months the stock Air Filter was not available,and I had also mentioned the same....The stock new Air Filter is good and ZMA owners can continue to use it wherever it is available.
My guess is the pads have not been installed properly and if you ride in the same condition the pads will wear out quickly. As an alternate, the Apache RTR front disc pads are direct fit in ZMA front disc caliper and costs only 350/-.
The spark plug lasts for 10~12 K kms only and must be changed for trouble free operation..the air Filter must also be changed in 8~10 k kms . both must be available at SVC...if not try outside.


Strangely the plug pic., shows oil fouling....when was your engine oil changed ? and how many Kms run on the present oil ?Check to see if the oil color is reddish brown...if so the oil is fouled and needs change.

Bangalore ZMA owners - I was trying to get tubeless tryes for my ZMA in stock size. Every place has only MRF and Ceat tyres and that too only rear ones.

Those who have changed it, please let me know where you have got the tyres and the price. Read quite a lot of pages back that it costs nearly 5k?

Check in JC Road near Lalbagh Main Gate. If you do not get it there, I doubt you will get it anywhere else in the city..

IMO
Optimal afr turns don't work when/if you have to downshift to maintain a specific speed . Eg: if you have to maintain a speed @ 28 kmph and you feel the top gear wont do it you'll shift to 4th gear . If the afr tuning were a bit richer you may be able to ride in top gear at that speed .
When you downshift it means that the engine is giving more rpm for a specific speed when compared to running in 5th gear . And more rpm converts to more fuel consumption .
What I'm trying to say is that one's riding pattern affects the mileage , whatever the afr setting . What applies to me need not necessarily apply to another person ,even on the same bike .
Till what rpm does the afr setting appliy ? ( or does it apply to the full rpm range ?)

My idle rpm is normally < 1200 in the morning . It hasn't given me trouble so far . What is the relevance of 1400 - 1500 rpm?
Best way to reduce rattling of fairing ( I am assuming it's just the front visor and not the entire fairing) is to use double sided tape before screwing it down ! .If it is the whole fairing which is rattling then check the mounting points under the headlight and on either side behind the indicators .
Spare cables , tools , air pump (footpump or electrical) if possible , a small powerful torch.
What can I say about your co-rides ... they are lucky to be riding with you !!

Checked there only. So I guess, I will have to go back again and check out. Guess MRF and Ceat are the only options available now.

Technically AFR setting applies till 1/2 throttle position, but after putting a considerable amount of km's on my ride with the slide stuck, I can confirm that the AFR plays an active part only till 1/4th throttle position, after which the mj comes into play.

Within a week's time will be ditching the stock carb, and going for a cable slide Mikuni/Micarb VM28, the ones used in CI 500.

No, sir, the oil is Ok. because I changed it (Motul 3000T 20w40) on 3683 kms & My bike is 4769 Km today
Everything is ok with my stock plug.
I will check the engine oil tomorrow if it is reddish brown.

The AFR setting works between 0 to 3.5 K RPM, after which the Throttle needle position+Main jet works till 70% of peak RPM, and only Main jet size Thereafter.


The Idle RPM has to be higher if the engine is tuned lean so that engine does not shut down while starting from a stop.
Slightly lower RPM will enable bike to roll on from stop IF the AFR is set a bit richer..
I have 3.5 turns AFR screw setting and in city ride I normally leave clutch without throttle in 1st gear to crawl along in traffic...my idle with engine warmed is 1,400 RPM..cold is 1,200 RPM.

If your oil is ok then the oil seen on the plug could be due to mild Valve stem seal leak.

hahahaha.. absolutely lucky they are
took everything, except airpump.

Yes sir my oil is ok as i checked now.
what is mid valve stem seal & what could be the cause of its leakage on my new bike ??
please tell me if its a serious issue, Should I make attention to SVC guys immediately or wait till my 3rd service. I am really getting worried.

Sir, one more thing in my mind, the g-power spark plug may be the faulty one, because in my stock plug there is no oil fouling
my stock plug is :

Sir is this a must ? my bike has done 14500 kms. I never knew that the air filter change to be done in 8~10 k kms. What is the "The stock new Air Filter"? is it different from the one that used to come earlier ?
