GS150r is a smooth bike with sporty engine note..............many people may confuse the sportiness of its sound with roughness.Believe me if anyone wants to taste real roughness then they are welcome to taste on a Hunk over 70kmph or on a RTR over 80-85kmph.My hands go numb whenever I try to push those bikes.No bikes are as smooth as the GSR barring the Unicorn,P220F,R15 and ZMA.....relatively close in smoothness.

But yes roughness from the GS150r is not from its engine but from other parts.By the term from other parts I mean,engine mounting screws,SJCS chamber over the head of the engine(its a fibre body located on the engine head-while on other bikes this place is solid metal),heat shield on the exhaust,chain and chain cover.Tell the SVC to tighten these parts up.

People complaining of high speed air lock and mileage should tune their carbs.......bcoz what I feel now is that most of you suffer from this problems due to the fact that the carb has remained at its factory settings even after run-in was over.And SVC usually does a truckload of BS when it comes to carb tuning.A wrongly tuned carb with high fuel flow would exhibit roughness on the bike.

As far as mileage goes................I get an honest 57kmpl under almost most conditions.....which is an average of severe in gear riding and clutch wearing traffic riding.

Right now I am seriously concerned about the rear brake on the bike which does not goes well with the Front brake..........and causes skidding.

I agree to your point, Hunk and RTR are rough.... But they behave the same throughout the ride
In our case, i shows multiple personality Haven't seen any bike behaving like this, that too even after a very few kms of ride...
fed up of tuning n things like that... Suzuki SC is supposed to know the best tuning method i suppose (i believe they r trained for their own bike)...

BTW, which batch is your Bike??? I mean, mention your month n year of purchase...
This issue is more to do with early 2009 models, maybe now they have rectified it...

On the contrary...........Suzuki SVC did an over rich job on my bike !!! They turned 6turns of the carb,as a result when riding back home,I got the feeling,that my bike is sounding very rough and deceleration of rpms is slower too !!!!!! The moment I rode mine I realised it.Do you expect that Suzuki would arrange a special training for all SVC guys that are recruited by local dealers or SVC owners ???? Believe me,they are just local mechs who tuned all bikes from Hero Honda to LML and they are working at SVC because they havent got provisions enough to set up their own roadside shops.If you still have blind faith on every Suzuki SVCs,sorry I cant help it.
Suzuki trains few select mechs,every company does that.And they are the ones who tune bikes with most possible issues like Hayabusa,Intruder,GSXRs.They service GSR,Zeus and Access only when it has turned so bad that it may tarnish Suzuki's image.How do I know all these??? Trust me,my family two wheeler mechanic has trained thrice at TVS motors in Hosur and was associated with the Shogun project and FieroF2 development.He tells me the inside structure of the two-wheeler industry.No wonder he tunes drag spec and race bikes and also the likes of 1972 Honda CB350F-inline twin.(picture attached below)

Its difficult for the learned mechs to pay attention all bikes.Our bikes are special to ourselves because its our hard earned money,not to them.To them,its just another number.Lets get on the reality.Our bikes require our own time to get better.

My Bike was manufactured on June 5th 2010(written on the Suzuki tag,when it was showroom new),I bought it on 14th June 2010.

yes, same problem like my bike.....

sometimes cool.. ,soft.., smooth.. & sometimes rough.. improper..

"Multiple personality"

@mathews,

Oops sorry I was mistaken, do post the mileage issue with history on suzuki complaints page and also tell them when you are going to visit the SVC and which SVC

You will get a call even if not visit the svc and tell them that you discussed this with suzuki and insist them to look in

SVC have some tool to check the mileage, but even though ask them to try the purana method (bottle tube & 100 ml petrol)

Apply pressure on them and keep on pushing them till you get satisfied (yeah am talking about mileage only.)

I got my bike back today.

The bike was smooth on the way home, no roughness at all.
That could be because they tuned the carb properly this time, or because it was raining and the engine never got a chance to get heated up.

Got the rectifier changed to CA series.
Unfortunately, i dont have any pics to compare the 2 rectifiers,
I just casually asked about rectifier change while giving for servicing, and got my bike back with CA series, didn't have to mail suzuki or anything like that.


@ mathewsyriac :
Well, i guess as a last resort, you should either talk to the heads of the showroom or mail suzuki.

Tell them your mileage has always been low and the SC people have tried everything and its still bad.

Your bike is different dude, it is a more redefined batch....
Moreover, the local mechs of-course as u said are not that trained, My self and Mr. kalyan (Trained by Suzuki & Service head) sat for tuning for several times, no use at all.. at last, i too tried tuning by myself, as u said more rich, engine sounds more rough, towards the lean side, it starts knocking...
All possible things we tried... U r lucky to have a redefined batch... if u were one of us, u'll also be commenting like us
anyways GS150 is a good bike for sure, few of the initial buyers had a bad time, thats all... Hope it will be rectified

Today i spoke to Mr. Kalyan and stressed about my issue.. I asked him to refer Xbhp too... He agreed to check the engine tomorrow...
I know Mr. Vinod since i bought my bike and was a very courteous person.. Actually, whenever there is any service camp or when the japanese came, he invited me to attend... Maybe this time I'll go through Kalyan...

About Mileage testing, they have atleast made me ride a minimum of 70 too 100kms with the 100ml mileage test People on the road used to wonder that I am a Crazy mileage tester

ahhh It was awesome ride...
there was heavy rain in first half, n total dry in 2nd half of journy.....
- yesss PHILLIPS 55/60 totally satisfied me yesterday it was night time n raining, ghats...

-i was able to drive in 3-4th gear in GHATS (Khambataki ghat having end to end length 24kms) with pillion

-bike peformed veryy brilliantly ......n 1 thing to tell, our bike is helll lot smoother than UNI n ZMA..(we were on these 2 + mine)...UNI starts vibrating at 75 again comes smooth at 85 (6500 ODO)..ZMA vibrates on hard acceleration(11000 ODO)

- PWR/ECO/BLANK.....in my case i drove 150km on PWR mode n got 42kmpl....rest 130kms on BLANK, got 53kmpl {both the cases speed was 80-100kmph}

-break in period is over ODO shows 1750km.

-Oil(SVC) has gone 1100km so far, when i go back to Pune planning to change it to xxW50...any suggestions???

HEY one issue MY BIKE GIVE WORST MILEAGE IN ECO MODE, N BEST IN BLANK MODE WHYYYYYY?????

hey MACH what setting you use for carb?? please tell
cold idle=?
hot idle=?
fuel screw=?
in general riding n shifting PRMs=?
riding mode= ECO/PWR/BLANK...
this will be very useful for GSpians who face mileage crysis or any carb crysis....

n also tell about the setting which factory does on brand new bike for run-in....what should be done after run-in???

hey guys
my dreams of owning a R15/P220 came crashing down when my dad crashed his honda shine (he is fine.). now i'm looking to buy a bike for my dad. i reside in chennai.

i was looking for unicorn but waiting period is 5months. 2nd option was dazzler its the same unicorn but my dad found it too odd (me too lol). then the new yamaha SX isnt up for sale yet and also mileage is a big question for a yamaha. so i introduced my dad to the gs150r. my questions are these.
1.he expects 60 around mileage (the old man drives @ 40kmph not more and in city mostly) will the gs give that?
2.he is 55yrs old. he has rode scooters,100cc,125cc bike. he rides my bike too(fz) but is not comfortable with it. i read the gs weighs @ 150kgs. will my dad be able to handle it? regarding say pushing or turning or balancing etc?
3.what about quality of the bike? service? spares? maintenance cost? does it need frequent maintenance?
4. compared to the unicorn what are the pros/cons of this bike?

also for people living in chennai. i reside @ mogappair.
there was a suzuki showroom @ anna nagar but it has been closed down.
any idea of any other showroom nearby?

thank you very much for your replies !

Guys, have any one tried the 'contact us' link in Suzuki website?
I am getting message delivery failed notification in my email. I wanted to know whether I can change the regulator during the next sevice.
How can we contact the Suzuki officials if their website is not functioning

@ MIHIR oil should be Xx - W40 other grades won't be good refer manual for more info

I won't advice for mileage tuning till you cross 3'k on odo (let the engine and other core components settle down)

@ yellowspunk, you haven't mentioned your fathers body built and height considering his age you can gift him a access or activa. If the vehicle is for multipurpose then let him do a test drive and decide.
GS150R with full tank petrol weight is 148 KG but normally its around 142 kg

If you are keen on 60 or 60 + mileage then try slingshot or any bike below 150 cc range

okk guys did my 3rd service though i wanted to go for complaining about the engine noise but i saw that i had already done 5700 kms so went ahead and did the 3rd service. As i had complained to Suzuki a guy called me up and said whenever you are free just tell me before you go for service. So called him up yesterday morning at 9Am then went to the SVC from 10-2PM nothing done on the bike even though the Suzuki guy called at 11:30 to check if everything was fine.

The works manager was searching for me and asking the clerk to tell him if any guy with my name came and told he needs to be taken special care of lol I was standing right behind him told him i am the one you are searching. Then the whole process started since i insisted on the guy who does the servicing of Busa i told the suzuki guy no comprise on Mechanic i need a good one. Since i did last service from the same guy who does busa service knew about the quality and i test rode the bike 2 times did like 10 kms with the SVC guy with me.

Filled the Satisfaction form but told the suzuki guy can only tell if the knocking sound has disappeared completely and doesn't come up in few days.

On the whole "you can't get things done from Delhi guys unless you stand on there head" And literally they were doing something for the first time with efforts.

Meanwhile the other GS owners and access owners were like 'What did you do'? They are like super afraid of you lol

p.s anyway the washing was pathetic and also the washing guy i asked him there is soap left on the back side told me any way it is going to get dirty when you drive out.

I told him then no washing is needed at all you should be sacked as well. Such pathetic response from even the washing guys

You should have slapped him

lol that thought did came to my mind but no matter what you do idiots will remain idiots.

any way overall i got some deep insights from the SVC guy yes indeed the busa guy ok he told me the knocking sound that even after you do all things no matter what the reason is the engine balancer technology that is just side by side to the Engine there is a spring and a rubber to reduce the vibes so when the engine gets heated it expands to reduce the vibrations which is what the whole GS is about driving at 100+ and no vibes. He also told me that oil does make a difference so asked me to change oil after 1500kms.

Some issue i noticed today was even after several kicks even with the choke my bike did not start so increased the idle a bit. I will see if this problem comes up again.
