I faced the same problem with my karizma....

There can be 2 reasons for the noise

1..If it is making the noise and the oil container is empty, than probably its making the noise because when the brake pad is touching the disk.... there is no oil and than it creates some noise...So feel the oil as soon as possible. (Do it immediately it may spoil the brake)

2. It can be that the brakes pad are completely worn and makes sound, when brakes are pressed... check the width of your brake pad...(If they are gone may cost you 1050Rs+)

There are two above reasons for the sound...dont worry the worse thing which can happen is you may need to change the brake pad...

It wont spoil your complete brake if you fix it as soon as possible.

If not may affect your disk, and if you have ridden only for 7k...the possibility of brake pad worn is less.

Its seems u need to replace the oil,Even for me the pressure in front brake while pressing is less and found the oil is low in level and asked the lone mech in svc , he replied that , it need oil change and add air pressure to make ur front brake lever UP, which i never understand the term filling air pressure???

Anup I was asking riders not to lug the engine...meaning not to keep pulling at lower rpms. GS has greater torque even at lower rpms and can drive along at 30 on 6th gear,and accelerate thereon.So I had warned drivers not to do this as this will create engine problems in the long run.....so as a minimum base figure i had indicated the rpms and gears...Shifting at higher than indicated is preferable to be in the idle torque and power band.
The normal practice is to shift 3,4,5,at 50% of red line RPM to get optimum performance.
However each rider will have a comfort level,in driving,including gear shifting, which need not be changed...

even the same was the case with me....the mech was not ready to agree that the engine noise was a bit harsh.....i know it was harsh and to check it i called both my brothers....they also own GS but the new ones and then the engineer present there wrote ENGINE RPM settings on the job sheet....wonder what they(mechs at svc) would be doing now!!!!

First of all AKFARA relax...I told you no offense taken.
Why was the Bore and Piston changed and at how many Kms ?Please update me. A new bore and Piston will not give noise.
If tappet is loose..clearance is high..then you get sound like " tick..tick..tick slightly high in tone .
If the crank shaft bearings are bad you will hear a sound like a un lubricated bearing noise...like a flour mill,at a lower volume.
If the connecting rod big end bearing is defective, you will hear a sound like hammer hitting against a hard wood(the engine oil damps the sound)" kat..kat.."
If the connecting rod small end /piston pin bearing is defective you will hear a sound like "ting ..ting " which will be sharp in tone.
If your bike is in warranty period please register a complaint,so that necessary work will be done free of cost and in time.

Not only you and my case , a orkut friend who owns a New model 2010 GS gets the same noise,and called me personally what to do, I am frustrated by this noise....I reply him that,Ur in metro city Chennai..and i am in a village like town...U have more choice (variety OF SC)...we are helpless unless suzuki provide another service camp with Skilled engg

What you have said indicates JAMMED Disc Brake Pistons..this had led to constant rubbing of disc pads which by now will be worn out,and may have led to low oil level.Only SVC can sort out this problem as it involves removing the entire disc brake system and doing a clean up,checking,and replacement of worn and necessary parts.

Akfara early 2009 GS engines had this problem and Suzuki had done either replacement or total change of all parts free of cost...please Lodge a complaint and get the problem corrected in WARRANTY.

Thanks bro for the reply. I've tried tuning myself after Mach50 updated the thread a few hundred pages back. I was also impatient in tuning when I did not get the regular beat of the engine and my RPMs were also not constant. I tried tuning the second time and this time I got a little better result. So I just hope that it'll get better by experience. If I do not try now I'll never in the future; and will have to depend on the SVC all time. I'm pretty sure I'll not mess up the tuning.
I actually do not know any thing practically. you know what ? I do not even know how to take the spark plug out, check and replace it. I some times wonder how to check if the SVC guy has really replaced the spark plug or not.. So I guess the "Do It Yourself" thinggy needs to enforced in ourselves that we learn atleast something. Small things like spark plug checking, chain cleaning & lubricating, changing oil filter, etc, can be done by ourselves which I do not know how to. am planning to start all these one by one starting with tuning...

I had been buying bikes from the 70s, and SVCs have never changed..most are undependable.DIY is the way to go..but a word of caution...Not everyone is mechanically inclined,and even then may not get it right many times.
Knowledge(service manual),Patience,perseverance,and enough money are essential.Start doing small things like checking,tightening chain,lubricating it,then spark plug removal, reading,and replacement,brake ,clutch check and adjustments, engine oil ,...oil filter change and refill ,refitting etc.
Most important have necessary quality tools with you before starting any work...and a knowledgeable person to help in case you have doubts , or unable to finish the job.

Sir i done that whatever u told........You ask me why u replaced the Bore and piston...The answer is in ur question itself ,as i read in the thread ,that Few 2009 batches had problem,that too similar to mine ,I called MR vinod natarajan south service head Suzuki personally ,he told to contact my main SC dealer in pondy which i did ,and later it was changed under warranty(But they not give me a voucher or show it, whether the Bore and piston is changed or not...bcos i was not present at site which is 150km away from me....As u asked it was 13800km i left the bike for B&P change and Now current odo is 15800km( i did service and change oil at 14550km)..During the period which i got back my bike after B&P ,The engine runs smooth and even i am sane rider always,ride the same below 4500RPM as RUN-in-Period....
Now the question is where to lodge complaints...because suzuki website have feedback page only ...there is no email id to communicate....Sometimes this feedback page also not work properly....So I called Mr vinod south head Suzuki to express my feeling, he told to do a CAN test for mileage..which i idid , But i am not sure about the whether the CAN test was done correctly(i mean procedure)...Then came about Noise part, The mech tell me that the sound was in ALL GS after running 10km
meanwhile Mr vinod told me there is service camp by march 2011 in Puducherry while speaking in Phone and MY SVC puducherry told before that he will arrange a service camp at karaikal itself after pongal...
I have 2 or 3 more months left for warranty to end, still don't know what to do where to post?
Did u see how my SC service center looks in the picture i attached...in my previous post....
It was endless story for few 2009 Gs owners like me

In suzuki web site i did just now in contact page with choosing service enquiry....

i get this reply

Hii guys, Once I had same problem. I was hearing a squeaking sound from disc brakes. The fluid container showed empty and when I asked S.C they just washed disc rotor and pads. The sound was due to accumulated dust.

In falcon's case since the bike has run only 7K this may be the reason. The container may be full and thats why its showing empty. By default one of the brake pads touch rotors a little. That may be the reason for heating the disc. Correct me if im wrong.

One of the ways to check brake binding is to ride for 5Kms without applying disc brake,then touch and see the disc temperature.New pads and disc will give very mild warmth. ..after about 100 Kms the same test will not produce any heat at all in the disc. If at any time the disc without applying the brake becomes warm or hot,then the disc piston is jammed,or disc is warped.

That clears the doubt. I thought the disc brakes works good at a particular temperature and the disc getting a little hot is advantageous. In MotoGP and Formula1 we can see drivers warming tires and brakes for optimum performance, we cant compare both yet the idea was same.
Again how can we ride 5kms without applying front brake?

Drive slowly,Use rear brakes and gear down shifting..preferably when traffic is less..may be night time.
A warm or hot brake is least efficient..for street purpose
