Ya, thats exactly how my engine behaves too..
Which batch is your bike from ?
(Mine is from august 09 batch, and i bought it in august 09 too)

Sometimes i rev to 8k in 1st, 2nd and 3rd gears and it seems to become smoother after that for few kms, did the same thing today too.
(i've used shell advance, shell fast trac, and the SC veedol oil. veedol was the worst, but this issue is noticeable with the shell oils too)

I'll be giving my bike for servicing(8th one) in 2 days, i'll ask them about this issue and tell them quite a few people got a new bore immediately after sending mails to suzuki, i'll update here on how they reply to it.

I have a pretty long list of things to tell them this time,
2 r***ing parts.
rectifier issue(BA to CA)
engine issue
fix the carb(this was my fault, i tried tuning and now the idling behaves weirdly)

Hi Guys,

Nice to see lots of new GS owners and useful discussions in the thread.. Keep going guys.. The amateurs (includes me ) need the help of the Pros

Ok.. Here is a quick update...

I have completed 9700km on the ODO... Running on ELF MOTO 4 GOLD 20W40 Mineral oil for the past 2k Km... The things I noticed with this oil are no cold start issues, engine gets heated very soon, good fuel efficiency (I am not sure whether FE is linked with engine oil)

Ok.. I got my bike from swapna suzuki (Anna Nagar, Chennai)... I was servicing my bike with them initially..But now they have shut down and I have go to ABT Suzuki (Nandanam, Chennai) everytime.. It was making me irritated to go to nandanam from ayanavaram for the service... Plus whatever the issues I say to them (includes paid services), the bikes comes back to me the same way (except for it is water washed and cleaned )... But I dont get time to get back to them and report those issues after their pathetic service...

My bro owns a HH Passion PLus and he services his bike in castrol bike zone (kilpauk)...
I went to castrol bike zone with my bro and asked a mech over there to take a ride in my bike...

The problems i reported to him:

1) Whenever I engage the clutch, shift the gear up and release the clutch the bike gives a little jerk and then moves freely. It was happening in all the upshifts (I was complaining this issue to suzuki service guys for almost 3 times but no use.. They said it was an issue with clutch play and they have fixed it but they havent found the root cause)

2) Silencer was misfiring rarely (Not often)

3) Rear brakes not sharp (A typical complaint of any GS owner )

AFter the test drive the mech gave me the following explanations:

1) He told that there is a part called wheel rubber (sorry that i cant give the exact term). The wheel rubber thing in the rear wheel co ordinates with the chain and other stuffs and helps in gear shifting. He told that if there is problem with that (maybe an issue with the part or due to improper alignment) this jerk thing happens. He also told me that this issue will make the chain to loosen very soon... Bang.. He was very right.. I used to go to local mechanics in 2 weeks after service for tightening my chains. He impressed me... He told that he will check it and change it if it needs to be (it will cost around 100 bucks)

2) He told this happens if the spark plug gap is not set correctly and if its unclean... He told he will clean the spark plug and the carburettor.. He also told that if the issue persists even after these fixes then there is an issue with some electronic unit (sorry for not giving the exact term ).. Then I need to go and sue the suzuki fellas

3) All the bikes with alloys comes with some rear brake shoes which doesnt wear off easily and doesnt give sharp braking.. I asked him whether its only with GS. He said nope.. He told that he has to harden it manually.. Then the brakes will do fine...

4) Checked the oil level and told me that it looks good and i can do another 1k easily

After all his professional explanations for the issues (I am not sure whether the SC guys knows about these really) I decided to go for the service with castrol bike zone.

GOLD SERVICE - Rs. 355 (the same being charged in service centers but with no resolution for all the issues)


That too this castrol bike zone attends to not more than 15 bikes per day with 6 mechanics (I know that suzuki service center runs with 6 mechanics for 30 - 40 bikes per day)

There are also 2 other services
1) Prime service (125 bucks - Oil change, tighten brakes and basic service) (I think Suzuki service center does only this )
2) Silver service (250 bucks)

He recommended to go for castrol racing synthetic oil for my next change (Castrol MArketing their product.. No offence meant here)

I asked him whether he has serviced any GS before.. He told he has got 3 customers who comes to him regularly.. He even told me that he ll get me an intro with them

This gold service has lots of other things (suspension adjustment, wheel overhauling, wax polishing, carburettor cleaning etc etc) which I forgot to include. Will post you in detail after getting my bike back

Hi,

some times my bike become rough ( mileage 45 - 50Km/lr)
and sometime become smooth (Mileage 60-62 km/Lr)

what is the problem?

Model - 2009 June
Date of Purchse - 09/09/09
KM covered - 8800+ km
Service - 6 Nos. as per manual

Guys,

What's this new Big Fuss about the Engine Roughness and Bore Piston Replacement ? As if the Rusting Issue was not enough.

I too own a 2009 GS purchased in May 2009 and have completed around 7500 Kms.
I am getting concerned about this Engine Roughness Issue. Arre all the 2009 GS Owners experiencing this Issue ? Anybody here who is not experiencing the Issue.

The Problem is that i am unable to judge if my Bike also experiences the Issue or no.

@ kaspermatt, falcon, mathewsyriac, adi231189, akfara, rajesh1136

What exactly do you Guys mean when you say the Engine gets Rough and you get some weird sounds from the Engine ? Do you feel Vibrations ? What kind of Noise comes from the Engine ? Is the Noise audible even if you wear a Helmet ?
I always ride with a Helmet on. My GS also sounds like a Mixer or Grinder while riding but i guess that's how it is for everyone, right?
Also, once you increase your Speed and Rev more, the sound of the Bike is bound to Increase. I also feel some Vibrations on Footpegs and a buzzing kind of sound when i rev more harder.
At what speeds do you feel this Roughness ? If you Guys can please be a bit more Specific?

Also, i am still experiencing the Alternating Mileage Issue that i had posted long back. Once i get Mileage of 35-37 and in the immediate next filling i would get a mileage of around 55. Then again 35 and then 55. So on and so forth. Is this in any way related to this Bore Piston Issue ?
And also, my 2nd Tank has started to Rust again near the Mouth Part.

Guys, please clarify my Doubts.

A doubtful mind will keep creating new confusion.
Let's get together as a group and request suzuki to arrange a service camp cum customer interaction camp to clear the cloud on this.

What's your opinion hmmm

@all:

I spoke to the manager of the showroom..

Suzuki is actually concerned about the sales of GS150 (considering its their best bike ), and they have sent notices to all SC's to rectify all problems in GSs immediately and inform suzuki as soon as customer reports it.
(and if its requires replacement, to change parts immediately too, instead of waiting for some suzuki official to come and check the problem).

So the main problem in our case is, the notice seems to be "lost in translation" from the showroom to the people in the SC.

So talking to the owners/manager in the showroom would really help, instead of just talking to SC people who dont know what to do.

And about the engine roughness issue, no recall or any such major fault which is common to all bikes. But the manager told me to report to him if i find any roughness or noise with my engine..
(I didnt report it though, i told him i've not ridden any other bike so i cant tell if what i'm experiencing is normal or not, and i told i'll check with other bikes and get back. )



@MACH50: ride careful bro. even i skidded at a U turn (which i was taking at 60 ), but the skid was because the was sand all over the curve !!


@MSN1: Ya buddy, we should really compare bikes to check the engine noise issue before directly going to suzuki officials. it would be embarrassing to make all the officials check the bike if its normal..


@manubhat: Hey, isnt your bike brand new ?
i dont think you'll have to worry about the engine noise issue, it doesnt start until the bike has crossed around 1 or 2k on the odo. and in any case, i dont think its there in the 2010 models.

About the engine roughness, even i was a bit confused...
But for sure, one bike showing different behaviors that too on the same day is quiet abnormal for sure.....
And why the mileage issue is not yet resolved in my bike, tried almost all kind of riding styles, still never crossed 48kmpl.... The SC changed the Carb too, after that Pick became very sluggish

@sshivakumar(pondy), raghunandan(bangalore), animhr, anup and mach50 please provide your inputs on the above ongoing engine issue

(I)1)Normal sound of gs is like characteristic,rythamatic thumping sound.

2)Sand grinding sound is the sound which we will be getting when we expect a turn/slow down/(steady speed) and accordingly lower the throttle and clutch is played and gears are downed to 2 nd or 1 st.

3)once you increase your Speed and Rev more the bike also emits sound proportionately.

The above are normal and acceptable....

(II)1)Roughness as i experianced:the bike exhibits the above 1) for the initial few kms after that it deviates and egine produces sound similar to boulders or stones not sand in grinder.but the grinder seldom grinds the stones to sand.i can here these nieses inspite of wearing helmet.Low intensity vibes can be sensed at the fot rest.(we cannot get these when the bike is on smoother side)

2)The bikes exhibits split personality......sometimes it is smooth with (I)1) personality through out the ride.....but most of the times it endorses (II)1)

I also request other members facing the roughness prob to furnish there experience if it is same as i experienced or different.

Welcome Bro.....
I normally used to ride very short distances and thats y i didn't notice this issue that much....
I wish that the main Japanese People should go through this thread and provide a proper answer to us......

Sure Madhu bhai..lets form a group and request them for a service camp..

That's a good gesture from the part of Suzuki, if true.
I am thinking of E-mailing the Western Zonal Head about these new Bore Piston Issues that have cropped up on the 2009 GS Models. Will aslo be asking him to conduct a Free Service Camp in Pune as i do not recollect any Camp being conducted in the Western Zone till now. But quite a few down South.
Another Question i had for you South GS'pians who have attended the Service Camp is, are these Zonal Heads themselves are present during these Service Camps to personally address our Issues ?
Lets see how it goes.
