Re: Suzuki Gixxer 155

Not all bikes require carb tuning. But each bike is different and different bikes require different tuning which is inevitable. Also, the engine output is related to a/f ratio. Why do you think manufacturers provide a tolerance value to the stock carb tuning, which is bound to change with time? Each bike require different tuning at different times depending on ride conditions. Feed it more air, the engine will overheat and ultimately emgine damage but better mileage. Feed it with more fuel, more power is obtained at the cost of engine life. Ultimately, it depends on the rider requirements.

Re: Suzuki Gixxer 155

[MENTION=46210]punarvasu[/MENTION].. I am sorry that your post was deleted before.. I am not saying that the factory default settings are bad but these guys are not consistent.
The response from Abishek94 gave me an idea on where to look from in order to isolate the issue. I took my ride to the service centre today and I explained my issue to the guy. He took her for a spin and agreed on my statement that there is a noticeable lag. At 10:30 am, he checked the airfilter vent checked for blockage opened the air filter box, pressure cleaned the same and went for a drive to check.
It was the same.
11:00 am, he came out and I asked him what the issue was and three guys told me that it could be a wiring issue..!!! "I dunno how that is even possible! :P" he Disconnected some wirings and reconnected all of them and then took her for a spin to see if anything changed but to my disappointment, nothing did.
He came out and then I asked him to check the carburetor and he said that he will check it and then at 12:00 pm, I was getting restless because it was already more than an hour and no one came out to give me a status.. I went inside and I saw these guys cleaning my carb.. They said that they could see water deposits on the inner walls and I was like how could that be possible.
I have always been using BP's petrol and never once I faced this sort of a trouble.
They cleaned the carb and asked me to take her for a ride which I did and guess what? The problem is still there!! Grrr. These guys ran out of clues and then blamed everything on the fuel now.
They asked me to finish the fuel on the bike since the tank was almost close to full capacity.
I don't find a place in my heart to believe the SVC's claim of a bad fuel then again its rainy so could there be a possibilty?! Confused again :P

Re: Suzuki Gixxer 155


No there is no possibility unless you left you tank cap open.
Try changing the service centre and see.

Re: Suzuki Gixxer 155

Every bike will have its maximum output and tuning is the process of getting the same depending on your requirement.
Obviously the company's settings will be on the leaner end to promote better mileage.
I will not say that tuning is for nothing
Even when it comes to setting an ECU, all you change is the air fuel mixture at different throttle positions along with the amount of fuel to be injected. you program it in process
But in the case of a carb, you set the AFR so that you find a proper value that will provide a good output through out various throttle positions. Since everything is controlled physically ..
That's my understanding. Tuning will not increase bhp or torque more than what the engine is designed to give but it is the process of finding the sweet spot. That is my point of view..
Lets not turn this to an argument
You can always correct me if I am wrong because there is always something new to learn ..

[MENTION=72198]Balgi[/MENTION].. No I never left cap open..
But there was like 2 litres of fuel on the bike before they gave it to me.. Could that be the culprit.
Have to find another service centre and check but before drawing my conclusion, I would like to empty the fuel in my tank. That's not a bad way to start is it?

Re: Suzuki Gixxer 155



The open cap bit was supposed to be a joke bro. My mistake should have put LOL behind the line.

The fuel that the company gives is never the culprit. They fill it mere minutes before handing over the keys to you. However they put some anti-rust fluid in the tank at the time of storage which over a course of a few days turns to water with the actual chemical in it evaporating.

Ideally this liquid should have dried up or should have been removed by svc or it can screw up the engine. Maybe that's what happened.
So go ahead and empty the tank. Its currently the best course off action for you.

Re: Suzuki Gixxer 155

Thanks mate.. will do that..
The tank cap in the gixxer will come off as you know it.. So i thought you mentioned bout that

Re: Suzuki Gixxer 155

Had a chance to ride my friend's bike few days bike, its an awesome machine guys, I would choose it over other bike in its class if the A.S.S turns out to be good enough. We made a small exhaust note and fly-by clip, couldn't make full review since it was diwali and had to return the bike quickly. I will post the video soon.

Re: Suzuki Gixxer 155

They're(ASCs) good enough. However, crying baby will get more attention as always. So, be persistent in following up issues if you find any.

I feel if owner shows interest in bike-maintenance then bike will last even longer.

Re: Suzuki Gixxer 155

Hi Guys,

Finally booked my Gixxer today(Black). After a proper test ride(last was as only a km), i was blown away even more. Only, Black is out of stock. So expected delivery is first week of november.

Also, this is an important question guys. Do you know, whether suzuki tune the 'Gixxer' carb uniformally across the country to a certain volumetric pressure? Or do they vary it according to the altitude of various states?

Thing is i ride in Bangalore where Atmospheric Pressure is roughly at ~90kPa. For people at Sea level, like chennai it stands at ~104kPa.
I noticed a couple of guys here from chennai reporting very good mileages from their gixxers.

Could this ~20kPa drop in air pressure be the reason for varying mileages,and also is there a way to tune the carb to adjust for this from the svc guys???

Also.....
HAPPY DEEPAVALI!!!!!

p.s- kPa = kilo Pascal

Re: Suzuki Gixxer 155

Glad to know that, quality is extremely good, so issues won't pop out too often. Anyone who is looking at this bike can take the plunge if their budget permits, FZ with its 12.9bhp doesn't impress me on paper, even my bike's old carb honda engine puts out 14.2 bhp, might have a change of mind if I get to ride it. If mileage is important one can look at bikes from segment below IMO.

Re: Suzuki Gixxer 155

To all Gixxer owners I just have one small question has anyone ridden the bike during rains in water logged roads.Since the height of the vehicle was a bit short in my opinion.Did anyone face stoppage or water logging in Silencer during rains?

Re: Suzuki Gixxer 155

Yes... I had to ride thru water logged roads once... I had no issues..I think it can wade thru 1.5 feet of water easily.... Eventhough the bike might look short, the silencer port is tilted upwards, which should give you decent clearance...

Re: Suzuki Gixxer 155

Riding in water logged areas was never a problem..

Re: Suzuki Gixxer 155

for every carb there is a IDLE screw and AFR screw. and all and any carb can be and has to be tuned. now coming back to chennai vs bangalore . dont make any changes. unless you need to hit altitude above 9000 ft. also "NO" the company will not tune the batches of bike as per the city or area. they will stay consistent.

finish the run it and let a few services go( a few thousand km's) for the engine to properly set in before trying any DIY and don't get the bike inspected/serviced at a local mech unless its emergency.
