Wow 37 is a really bad figure. How is your riding style?
Sometimes even I get the feeling of low engine power on lower speeds but as I am new to motorbikes when i compare my bike with my friends CBZ(10000kms) but he said all new bikes feel like this and only after 3-4 servicing bike engines gets properly tuned.

You have got me wrong

my riding style is very very smooth below 40-45 speed I don't like over speeding. Like to ride in peace without tensions. Well right now I am getting 50 initially I was getting 37 i.e. Before my first engine oil change. I am using moto 4 gold 20w40 oil. Changed it twice buddy till date. I have clocked like 980 km from the date of purchase. Today after getting my mixture open little bit not much still the problem has not been solved I think I will ride her for few more km then shall get the right kind of tuning done. Sometimes it feels my bike has got cough. It gives me real bad jurks at 3 gear and 4 gear as soon as the rpm reaches 3000. u can Accutally feel like the bike not pushing as if there is no petrol left. More over in the morning even if you have used choke for the first time for a min or two when u remove the choke and are set to take her for a spin the bike starts giving you so much of jerks and it is so hard to even raise as if u can really feel of no petrol being there even after the tank has got 10 ltrs in it. I really would love to know here who all had faced this problem and how did they manage to solve it. Please please do give me an answer friends as this kind of a thing has happened with me for the first time and there is no experience here with me on this....Thanx in advance shall await for a reply at the earliest of what to do.

Filter, plug....may b the culprit

Hmm just checked on 3 brand new unicorn from the dealer and the last part of thing is that it is present in all of the new unicorns which is coming Also I have surf the net a lot on this and the last remedy is to live with it I guess it has come in virasat for unicorn.Nothing can be done. I might make a whole somewhere for the air to pass lets see just enjoying my jerky rides. For present

the jerks & 'outta fuel' symptoms can be caused by the following:
1. Bad fuel
2.Spark plug (swap with another plug)
3. Petrol tank 'air lock' - try driving a bit with the tank cap unlocked.
4. Fuel lines/petcock blockage
5.Carburetor (jets may need cleaning) - i have faced this issue and found the jet to be blocked (with a tiny strand of cloth - this probably entered thru the fuel or when the carb was cleaned were mechs use teh 'waste cloth' stuff to wipe off stuff. (it used to run 'normally' when the choke was on, i had to use the choke for 500m to get to my mech lucky i was close by to the mechanics' place when this happened. )
Earlier when i faced this jerks suddenly out of no where, i just pinned the throttle and rode for a few 100m at full throttle and the prob disappeared. i guess the jets were 'cleaned' due to me opening the throttle fully.
6. Airfilter clogged -(i have faced an issue due to this also) - i simply replaced the filter, because for some reason even after tapping the filter and blowing it with compressed air it was still jerking/gasping at times (this was on my honda dio)

I would suggest start checking in the following order -cleaning out the airfilter (or swap with another filter), then clean your tank and the petcock, if not have the carb opened and jets cleaned & ensure the float is not sticky.
cant think of anything else right now..

Finally the problem has been solved yes guys u heard me right. Changed these items 1. Air filter since the bike has done 1050 km 3 times the engine oil has been changed 2. Tuning of the carbrator which I guess made the thing be perfect the bike is just rocking now I love it. 3. Just for precaution I changed the spark plug also not to keep anything for secondary and I rode it now I am happy with a nice smile.

glad its been fixed

(facepalm) You never tune a bike thats undergoing run-in, all new bikes are set a bit rich, cause during run-in the engine heats up pretty quick due to all the friction and hence needs to run rich so that it doesnt heat out of proportion, thus enabling proper and uniform wear and tear. Thats the reason why all new bikes have very less mileage figures.

No harm after 1100km

hmm ah I did not know that. Ok ok buddy the thing is as for the run in yes even I know all that since this is not my first bike now see this Engine oil changes 1. 300 km 2. 700 km 3. 1050 km The mixture was touch only after I have done 1100 km ok yea yeah I know this also that we say that the run in goes till 2000 km I know that. But there is no harm in 1100 km. Getting it touch well if u see when you go and purchase a bike who knows the bike which you are being delivered the person has not fiddled with the setting? See there is no harm in getting it touch from outside not getting it opened. But but after 1100 km you can touch there is no harm. And more over at the end of the day my problem is solved I am more concern for that rather this that the dam run in is there. As I know what I am doing best for my vehicle.

I know its not your first bike cause I saw your sig, but just posted so that new users dont get confused.

Here's an experience I'd like to share, dont know if the impacts are directly related to carb tuning, but thats the only thing that was altered between these rides, and both the riders are sedate riders, with some minimal ripping.

I have 2 friends both of them riding the same bike(Engine wise.) purchased around the same time.

Case 1 (Fazer)-
Was getting around 32~38Kmpl when brand new, his carb was untouched and he did proper run in, and now getting 48Kmpl average.

Case 2 (FZ-S)-
Was getting around 35~38Kmol when brand new, he tuned his carb for mileage during 1st service, he was getting around 50Kmpl IIRC, but now his mileage is around 30Kmpl average. And he too followed proper run in.

Hi Guys,
I will be completing one year with my Unicorn next october. It has done 9k km. Last free servicing was done on 5k km. and I changed oil at 7.5k (apart from that no work is being done after free servicing.)
No problem with bike as such, now what are the things to check? Should I take it for servicing?
I will be changing oil after 500km more.
Need your advice. Thanks in advance.

I agreed if u touch in the initial stages for the average you will get good fuel effe but later u will get poor average as the engine settles down completely again at that time you have to get your carbrator re-tuned in that time. So I also know it comes in my case to. good to hear you will be completing 1 year well in your service change your oil it will be good for the engine. Also just follow the book which r the stuff to be replaced in this time for the better ment of the vehicle how is your cone set. Change the lock of the chain sproket all the best

Hey guys I just wanted to ask about a problem I'm facing. There is a squeaking sound every time I get off the bike. I'm assuming it is from the suspension since its coming from under the seat Also I feel the bike suspension is a bit soft as I'm getting a bouncy ride. Solution?

Thanks

well this problem even I hear it is not a problem first of all if you make it hard then there is going to be a back pain let it be soft buddy trust me I have gone though this.... So I suggest u just ignore it. Ok the sound as u sit there is a sound right other than that there is none if u see closely from the place where we kick underneath the seat if u remove it there is a nut right this nut adjust itself when we sit and that makes a sound see for yourself I did and came to the conclusion to leave it. Just ride her buddy love it as always.
