hi bro, sad to know that, anyway there will be some solutions and am looking really forward

The mechanic i met was a HH SVC guy who had some 18 years experience in HH SVC, seems like he had seen such kind of problems in karizma
But the SVC which i visited was in THALIPARAMBA(Place situated in Kannur) it was a very small SVC and there was no sophisticated equipments for further investigations

If you are sure that the problem is same then coming here will be a waste of time Because These SVC have nothing to solve this

Sunday am leaving to Bangalore and hope i can find out some good mech out there

Anyway i will post all updates here, plz share yours too

Where are you from?

TPS- Throttle Position Sensor AFAIK TPS connects CDI to carb

HI dude, if you are running with a local airscrew ,change it to a genuine one Before going for any DIY work,
check your carb insulator for any damage,I think this itself will solve your problem to some great extent
Since you have a great evident of decreased top speed, i think there is nothing to worry about like me...
My bike Doesn't have any problem with Top speed and daily am doing 120 ease and 140 maxx

PLZ KEEP UPDATING YOUR FINDINGS

Did somopne play around with the carb or the surrounding plumbing? This is an airleak! and not due to the airfilter! how much mileage have you been getting? have you checked the choke plunger in the carb?
if you take out the side panels, you will notice that there are some black tubes that go into the left side of the carb. this tube goes and connects to more tubes with the help of a plastic T joint. One of those tubes also goes and connects to the intake manifold.
The problem is that either one of these tubes has got a crack and is letting in excess air or the brass joint at the intake manifold has loosened up and is letting in air.
Ive experienced this problem on both my zma's and had to figure out and fix them myself.

Cheers!

thank you james brother for your valuable information, Even few mech pointed on the same, but there is no visible proof of air leakage. Even i thought of changing the chock cable and insulator but the unavailability of parts stop me, Tomorrow am riding to Bangalore and AFAIK Parts are available at there, i will change them and check the difference..

The bike has been runing on the local air-screw for a while now and is currently not available with any of dealers here in Delhi NCR region . I will try and check for cracks on the manifold rubber firstly befor i open the carb.
Also, when i start the bike in mornings i need the choke (since its really cold up here i Delhi) and after a while the rpm increaces like mad upto 5~6 K and stays to that point .This should not happen, or is this normal. The service engineers at HH are not doing anything about this and am not finding any good mechanics here to reslove this.

OT: A very interesting find on www.team-bhp.com.

Vineet, do you have any tappet sounds? Another reason for your bike's behaving may be cause of tight valves. Also check choke cable if it is right.

HI bro go on with your DIY work, Tomorrow Am leaving to Bangalore, will check the availability of parts out there,
That's the same problem which am Facing From past 1 year Bro, But this time am Planning to check Every little thing possible,
if you could borrow a friend's Karizma air screw and try to fit it on yours. If this solve the problem then you will have the solution

MY KArizma mods... is the one of the best thread that i had come across so far and the person who started the thread is Mr. Sankar who is a Brilliant Automobile Expert and AFAIK He lives in TVM, Kerala, i used to dream about my bike being inspected by him And i strongly Belive that with the help of someone like him,i can solve my problem i was a silent Reader of the thread and Many times i Tried Get an account in TEAM BHP but i couldn't
Even MR.sankar is a member of our XBHP but i think nowadays he is not active,
AFAIK Here in Xbhp There are many Experts and few of them helped me a lot but bringing Their suggestions into practice was a bit Difficult because of the poor Man and material availability
But you really makes me to wonder, saying that am not finding any good mechanics here to resolve this. Being in Capital, i think there will be a lot of Mechanics wwo can solve the problem and i hope you can find one soon

GOOD LUCK Bro

Hi Ravi Brother first of all am Thanking to god for making your attention on my Problem

Brother sorry to say that i don't know anything about tappet sound and how to assess it,

Tight valve! so what should ido?

Am gonna change my choke cable soon, since the Part is not available here(Kerala) am Planning to change it from Bangalore

Brother i now Remember an issue that was happen before some Two years During the service, i told to adjust the air screw But mechanic informed me that the Air screw is jammed and could not be adjusted. later they extracted the screw and re threaded the carb after this every thing was fine,
Is there any relation with the above incident and my current problem

Vineet, I too do not know the exact cause of your problem. What we can do is, list all the suggestions given by the experts here. Eliminate one by one by checking/rectifying them. Ultimately we definitely can find the solution for that.

You said the carb is cleaned and properly tuned. So it is not the problem. then as somebody suggested, hope you have checked for any breaks/leakages in air channles to the carb.

I found that, problem with choke and tight valves may cause the revving problem. You have not yet checked the choke, so try and rectify the choke. Still if the problem persists, just ask an expert mechanic to check for tight valves. Based on his inputs, we can go ahead further.

Do not worry, we can find a solution. Contact rockkyyy (aswin) from Banglore. Somewhere he mentioned that the service at millennium motors is very good. Next time, try this service center. We will see what we can do next. If the problem still persists, we can mail to Hero Honda main office and get things right.
