...but my bike chokes over 9.5k like no fuel maybe the rev limiter comes into play then. i dont knoww what is your bikes exact problem. there are more expert people here who can definitely help you.....thanks

The revv limiter limits the throttle and so it wouldnt make your bike feel like running out of fuel at that mark. so it might be a tuning issue.
Did you do any mods on the bike?
At what rpm does your bike redline?

Making a rich setting is ok, but Too rich can do bad to your bike as fuel intake will be more than required so the mixture wont get burned completely hence will result more unburnt particles and carbon deposits. optimal range is enough for a good throttle response.

i dont think mine is too rich, it may be close to ideal.i know rich setting may cause harm but i meant that i'll prefer rich setting than lean setting.


Sorry bro am not familiar with that, and sometimes it wouldnt be that exact in every case. I own a pulsar 180ug3 and its said to be 2&1/2 turns for my bike, anticlockwise from not so tight, but it doesnt suit mine.
May be your SVC can tell you.
ok no problem.i posted it in ownership experiences thread but got no reply (i'll try again) so thought of asking you & you might have friends who knows about it.


hollow sound (too lean setting): here the pitch of the sound will be more and the burst-sound duration will be more. the sound a bit similar to that when we remove an airlock from a water tap, by just closing it for a few seconds creating a pressure inside and leaving it all of a sudden.

Cracker sound (too rich setting) : something like phatt phatt similar to crakers.. these bursts have small sound duration and the interval between consecutive bursts are less.

lean/rich setting can be identified by examining the spark plug after 30kms of the same setting. white deposits indicates lean, black for rich, reddish brown for the correct ratio.

ok i got it now. i know about the spark plug thing but the funny thing is i cant open the spark plug by myself using the stock tools

No, not if itz just once. itz the same idea similar to running a bike without oil, no friction busters so more wear and tear, so can damage parts. no prob if itz just once or twice.
thanks bro you saved me.i couldnt sleep that night

so when the rev limiter cuts in how does the bike feel???? i thought its because of the rev limiter. you mean i'm running leaner??? my bike red lines at 9krpm. i didnt do any mod in my bike.everything is stock

Revv limiter just wont allow you to accelerate more and thats all what it does. what is the top speed that you get here? where does your bike rpm meter shows redline. Am not an expert but i just know the basics thats all.
I think it might be a minor tuning issue, does it hesitantly accelerate more after 9k, or is that the final that your bike does. How do you feel accelerating past 7.5k. observe and post.
Take it your svc mention the 9k mark and the choking effect and ask them to tune it correct range (performance) mentioning your need and specifically tell them that dont tune it for mileage but tune it to correct range, be with them while tuning and observe it. and ask them to test drive.
You will get an idea. and this would be the better choice.
and it will help you to experiment later (if you would like to) by remembering the no: of turns. Though experimenting tuning every now and then is not good for your bike.

actually when i get past 9.5k my bike doesnt take any throttle response. my bike redlines at 9k. i dont go above 9k actually coz cbz x doesnt provide any power above 9k.its just that sometimes i pin the throttle to see how much it goes.

^^^ Vaccum in fuel tank; there're quite a few threads where this has been discussed. Pls use the search feature

let me open the fuel cap and close it after few seconds

That's half the solution, just to check if vaccum is the issue. If you need to fix the issue permanently, you need to open up the breather hole.

I don't have any idea about this breather hole. What is it and where is it?
