Re: Suzuki GS150R

Thanks Bob,

I have already checked the mileage with mileage can..(21.5 kms/500ml with mileagecan on highway 50-60kmph .....so 43 kmpl on highway )
no change in driving habit before/after service...

Re: Suzuki GS150R

I hope you haven't changed the fuel station; what I mean is, you're filling the fuel from the same fuel station when the bike returned 60 Kmpl.

If I may suggest...please use average method of reserve to reserve mileage check rather than 500ml or even 1 liter. This means...
1. Note down the ODO when the bike hits reserve
2. Fill the fuel for some 8-9 liters (or even more as I don't know the capacity of GS)
3. Ride as normally as you will
4. Note down the ODO when the bike hits reserve
5. Do the calculation as [(Step 4 - Step 1)/Step 2], which will give you near to accurate FE

Re: Suzuki GS150R

Suggest you changing the fuel station once and check.
Also, check out the tire pressures from a roadside tire shop, if you're filling air from bunk itself. The inflating machines in some bunks are inaccurate.

Re: Suzuki GS150R

SatSon is right. As per the manual the rear tire pressure should be around 33 and 25 psi for front. This could be a reason. But getting this low mileage for prolonged period could mean that you should evaluate for other factors too.

Re: Suzuki GS150R

Does any one here know the price for choke cable of GS150R. Changed Choke cable today and in the bill it is mentioned as starter cable and the price is around 135.00 which is expensive than the complex clutch cable assembly. Just wanted to know if they have overcharged. Service centers are known to do such things.

Re: Suzuki GS150R

Hi Durai, did you find out what is causing the mileage drop?

Does any one know when a when GS150R is the due for decarbonising and valve seating. Lately I've been hearing the tik noise related to tappets or valve from the cylinder head. Seems like the service center guys skipped the check, inspect and adjust procedure of tappets clearance for more than last couple of general services. I asked them to do it in the last visit and according to them it's a complex job and skipped it shamelessly when they already had to remove the fuel tank for other works. My belief is that the clearance can be adjusted in 15 minutes and less if the fuel tank is already removed. Does not able to adjust tappets periodically causes damages or higher maintenence cost? Any suggestions.

Re: Suzuki GS150R

I don't own GS, but in general for a 4S bike running in decent condition with right carb settings won't have much carbon deposits. If you have done more than 40k kms, it is worth checking and decarbonising if necessary.
And, yes tappet adjustment won't take much time, but the mechanics are always reluctant to do this. They will say - "If bike is running and starting without issues, no need to touch tappets"
Little bit loose tappets won't do any harm AFAIK, but tight tappets are bad for the valves. Also, incorrect tappets can cause in drop in power and mileage.

Re: Suzuki GS150R

Thank you Satson.


And this time I want to share some of my experiences or rant for only the people who would have some time to read through.

The experience with ASC (2) in the same city in less than two weeks
Today I visited the service center right after the lunch break (around 2:00 PM) and they refused to check and adjust the tappets (valve clearance)and this was the fourth time. Got the same answer that they are all busy as always even when I told them that I am ready to wait for 2-3 hours or end of the day. And then in the end they asked me to bring the motorcycle in for the valve clearance setting in the opening hour so they could check and this would be the 5th time in two weeks. Why this is so and I am not understanding why it is so tough for these people to set the valve clearance which should be done during every general service.

Now the experience with another ASC(1) in same city in last less than 33 days.

• First visit -

Skips the valve clearance settings even after asking specifically for the same while admitting the motorcycle for service. Then later I find out that the chain is not checked cleaned or lubed or the points to be greased or lubed is not attended. ASC adviser accepted the blunders and requested to bring in the motor cycle in for the pending services next day.

• Second visit -

This was just to find out that they just cleaned and lubed the chain and didn't even bother to grease and lube the usual areas. And again they just skips the valve clearance inspect and adjust. Arrrrrrgh.

• Third visit -

This time had to change choke and clutch cable and shifter rod because not being able shift the gears when needed by heel or toe and this would result in accident Adviser advise me that the 1.5 inch of play for shifter is ok. And I told him that I would take no for an answer as the most of the time pillion is my son and just change that damn shifter rod and arm. Of course, the long pending valve clearance as the sound from the cylinder head is getting louder. Tried to convince the adviser that I need the valve clearance really badly as I fear that I would end up paying up for damages caused by the poorly set valve clearance.

He gets charged up the goes on explaining that how much they are busy with work and their tech being so damn busy and on top of everything valve clearance is time consuming and has to remove fuel tank assembly, in short they don't give two piece of sh** less if my motorcycle gets damaged due to their laid back attitude and won't give a F**K if that cause a dent in my bank account, excessive valve guide and valve seat wear, broken valve train components (springs, pushrods, lifters, camshaft), poor running engine and low performance, limited lifespan of valve train components, ahh and the least important one blown up engine!!! oh by that we could enjoy awesome F**KED up expressions on the face of poor Suzuki customer when they get that F**Ked up expensive bill and those expressions would be F**KING priceless for us and makes our average ASC day so F**KING complete.

Oh and here is the best part after an hour of waiting they F**KING prying off the damn fuel tank assembly and side covers to change that most important choke cable. ARRRRRRGH ... what about the F**KING valve clearance dude the F**KING valve clearance it would just take another 10 minutes ....just another 10 F**KING minutes that's all it takes ... Oh I forgot the important advice of adviser that how much F**KING busy their tech are .... Me facing the closed glass door to the service area which says NO ADMISSION so boldly. Later I found out that they won't even inspect or adjust the valve clearance for any motorcycle during the free services which is clearly mentioned in the huge information display of service works break ups clearly mentions that the valve clearance should be inspected and adjusted at every service .. Isn't that F**KING twisted.

I love the marvelous thoughtful engineering and machine made by Suzuki and respect their heritage. But why do these clowns are there to spoil it and doesn't care about customer or lacks professionalism.

Re: Suzuki GS150R

Hello All,

Got my 2nd free service done today. The odo reads 2209 Kms, service was cuz of the 'number of days'. As per the manual, the oil filter wasn't required to be changed, but it would cost Rs 32, so, I asked to change it anyways (since the engine oil was getting changed). I asked them to check chain tension and they charged me Rs 90 for "chain drive lubrication and cleaning" in the bill. I asked "this is part of the service, right?". They said "no, labour charges are free...all other work will be charged". I don't know. Also, Rs 40 for some battery maintenance. Next time I will asked them to tell me about these expenses BEFORE they do something, maybe I am wrong but they made it sound like just 'washing' is the 'free' part of the service. Anyways, I'm still learning to recognize these 'tricks' to inflate bills.

At the time of delivery of bike during time of purchase, I got a free 3M coating which started coming off and some 'marks' were visible in some places. So, I got free 3m coating done again today saying that it was told 3m coating should last 6 months, now is only 3. So, that was good.

From the above discussion in the trailing thread comments, I would like to add that the fuel indicating 'bars' can be misleading. I have often observed 2 bars becoming 3 and vice versa depending on if the bike is on side stand/main stand and when bike is in sun(hot) and bike is in basement parking overnight (colder condition). Even the manual says that the bars are for indication only and the actual fuel quantity can be different. When I got the bike on delivery, the last fuel bar was already blinking (based on manual the blinking bar = 1.5 liters of fuel).

For checking mileage, most accurate method seems to be the filling of the tank cap till the brim - note odo - run for a few hundred kms - go back to petrol bunk - fill it again to the brim - check the odo again and the number of liters of fuel filled. The same is what @aargee has explained step by step above. I agree with some other users who have mentioned that a 100/500 ml fuel test bottle may not give an accurate figure.

One more thing I would like to add - the tyre pressure front/rear - 25/29 (solo) and 25/33 (with pillion) are "COLD" tyre pressures. But actually by the time we take the bike out from parking and go to nearest petrol bunk OR mechanic, if it is already 1.5-2 kms then the tyres are already considered "warm". Warm tyre pressure can be 10% more than cold tyre pressure (based on articles which I have read online). I go with the standard 26/36 settings for air pressure (also cuz I am riding with a pillion most times) which is used for most of the standard 2 wheelers at petrol bunks. Bike running fine. Mileage around 52-54 kmpl (a lot of pillion rides) with ECO mode running between 40-60 km/hr most of the time (subject to traffic)

Happy and Safe riding!

@DaddyBob - The guys at service center skip this check and say "we will do it only if the owner is complaining about a HUGE sound OR if something is really wrong. Normally it shouldn't be necessary to do this". I don't agree with this cuz manual clearly says that tappet clearance needs to be checked and adjusted (if required) BUT when the service guys themselves are not confident and trying to escape the job, I feel if I force them to do it and then they make a mistake (cuz maybe they have never done this before) then it will be trouble for my bike. But in your case, with clear audible sound/noise, a tappet clearance check is really required. If you've not done it already, then you should make a official complaint on the website AND also call up the phone for the official suzuki representative for the region. His number is usually displayed on a poster in the service center.

@Durai - Have you located any solution to the mileage problem yet? I was at service center today and so these words are fresh in my mind...there were posters which said that the basic reasons for poor mileage is:
1) Using excessive clutch
2) Riding in improper gear
3) Too fast acceleration
4) Overloading the bike
and some more points, I can't remember all. Since you have already checked and done a lot of troubleshooting yourself, maybe try to go to a SHELL petrol bunk and see if it helps? Maybe your petrol bunk is good since you've got better mileage previously from same petrol station, but no harm in trying something new.

Re: Suzuki GS150R

1. i beleive and have experienced that ASC are useless piece of
s h i t be it Honda or Suzuki
You can see my post regarding COMPLAINT to honda about service centre when i was asked to change OIL AND FILTER even though it was all very good and while i had given bike in service all they did was WASH... seriously i cud not find any greasing or oiling, no cleaning chain or lubing

2. Even local mechanics are useless why ?
Because there was a creechy noise coming out of somewhere and local mechanic thought it was coming out of FRIN DISK BREAK PAD so he SWIPED SAND PAPERS and made it look ugly later he found it was just side pannel loosened !!! He just tigthened the screw !!!

3. recently i had posted on something similar about my unicorn and a fellow xbhp member suggested that get TAPPET adjusted
i roamed about to see few mechanics everybody found my engine to be ok ! Theres no prob for them but i can feel that something is loosened in the engine head and it makes noise as i accelerate slowly but yet have not found anybody who can understand my problem

Re: Suzuki GS150R

Sorry for late updates.

Price - 88K including accessories around 2k.

Milage -
11 Ltrs (<1 at the time of delivery+ I filled 10). Yesterday it came to reserve, odo showed 320 kms. If reserve is 3 lets then it ran 320 kms for 8 ltrs.

40 Kms per ltr. Hmm, neither good nor bad. I have to wait for first service, run in ECO mode to get a smile i think.

Re: Suzuki GS150R

Today's update.
Reached the service center in the morning and again another guy who is in the duty as a adviser.
And the drama begins again. I told him that I am here to get the valve clearance inspected and adjusted, which is due since a long time for at least. 22K kilometers since you ASC guys don't give a F'ing s**t . So without even checking or starting the engine he advised me that it will be OK and does not need any adjustment.
Then I had to advice the adviser that it should be done every 1K for the first 4K and every 4K / 8K after that. So just get it done. And told him the story that I am pissed off and fed up because of their laid back attitude.
Later the a another adviser tells me that it will take to much time and I could come and collect in the evening. Then again I had to advice him that this F'ing procedure would just take 15 min as the engine is already cold. And this is the F'ing 4 th or 5 th time I am coming here to get this F'ing thing done. So he got the message and became silent instantly and finished filing up the job card. Now I am waiting... Will update soon. [emoji3]

Re: Suzuki GS150R

Daddybob, why so angry about valves?! So many *** and coloured language? Relax, issue will be solved. Else mail from the suzuki website if you haven't tried, that might work too.

Re: Suzuki GS150R

2+ years and I finally managed to do a 15k on odo.

*Replaced both spark plug and air-filter at 13000 kms by myself .

*Pending jobs - front fork oil change (might do in SVC only) and brake fluid replacement.

*Carb is still factory-set, bull returns 60-65 kmpl on highways (60-65 kmph @ 6th cog, absolute minimum braking and re-acceleration).

*Valves/tappets untouched

*Getting a peculiar grinding/vibration at 4000-4500 RPM, uncharacteristic of GS - tightened the lower engine mounting bolt-nut after removing
right foot peg. My Taparias fouled with the crash bar so couldn't tighten the front ones. Observation: When the vibration happens, silencer vibrates like mad - is it actually silencer vibration and nothing to do with engine?

*OEM chain loosens easily and too often !

RSK, did you get your 4000 RPM vibration solved?

Re: Suzuki GS150R

Silencer resonance vibes are only felt at ~3.5k rpm. I solved it using the rubber washer technique found earlier in this thread. YOu can try this as you are saying silencer vibrates.

Apart from that once I had vibes at ~4.5k rpm. AFter much close inspection I realised that the vibes were because of the front leg guard. I removed that guard and all the vibes were gone.
