Re: Suzuki GS150R

Good to see activity on the GS 150 ownership thread. Its time the rest of us pitched in as well.

In between my travels I haven't had much time to use the bike and took it out for servicing today after a long time.
And boy, after the regular service and a couple of cable changes, it feels like new again.

I was looking for an option to change the tyres as well since I was still running on the stock ones and needed a new pair of shoes for any long rides that I may take.
Decided to switch over to tubeless as that would be more useful when on a drive.
Was looking for options and could not find much.

The websites for Michelin and MRF do not offer much options for 18 inchers.

MRF has the stock Zappers, front FS and rear Y in tubeless.
Michelin had the City Pro available in tubeless but not the Sirac as per their website.

Was also wondering if I should upgrade the size to a little fatter one than stock and try if that makes any difference.
I know it is recommended to stick to the stock size, but what the heck, you can always change.

Was trying the forums but did not have much help on for choosing the right tyres.

Finally decided to go out and explore in the shop directly and find out what options I have.
After some window shopping and asking around , finally found and concluded on the following set.

Front : Michelin City Pro 80/100 47 P Tubeless
Rear : Michelin Sirac Street 110/90 61 P Tubeless

Its still the first day and I will wait before I pass the verdict, but they do feel good on the first ride.

My choice for 80/100 was only that I wanted to move away from the stock size, and theoretically the 80/100 should be bigger than the 2.75
But side by side, there isnt much difference between the both, and if any, I felt the 80/100 was marginally bigger than the 2.75 by an mm or two.

And the 110/90 obviously since I wanted a bigger tyre, and also since it was a Sirac and it was Tubeless. (though Michelin's website does not tell you so)
BTW 110/90 does fit comfortably.

So all in all, I got the tyres what I was looking for, and hope it helps others who are trying to find a fit for the GS.

Got the tyres done at MV Tyre Plaza near Satyam Theatre , Ameerpet , Hyderabad.

Cost - 1800 for the front, 2800 for the rear. 200 for the steel valves for tubeless and 60 for fitting. discount -100. Total - 4760.

Re: Suzuki GS150R

Welcome to the thread ! I too have idle-d my GS for long. What cables did you change? How many kilometers has your GS done?

Re: Suzuki GS150R




Oil Leaking issue in my bike.

I could see wet patches near gearbox [photos attached], it leaks 3-4 drops a week while parking.

Is this a serious issue??.

Re: Suzuki GS150R

Yes, it is.

Over period time, the inner ring of engine cast or screw's ring looses its grip, could be due to frequent bolting or over tightening. Inspect carefully for solution.

Re: Suzuki GS150R

Did you carry out the AC to DC conversion by yourself/mechanic or was the magneto cover opened at any point of time?

It looks like the oil is leaking from the magneto's wire - the point where it exits the case, or from the starter motor gear cover. If it is leaking from the magneto's wire, an Anabond sealant could be used as the set of wires alone are not available as a part to change. If it is leaking from the starter motor gear cover, renewing that gasket would solve it. Also, remove the front sprocket cover to check whether the neutral switch and front sprocket seals are okay. Another culprit would be the magneto cover gasket itself, if you have removed it for something.

This is not a "serious issue" (in terms of cost involved or damage) and could be attended at the SVC. Keep an eye on the oil level and attend to it ASAP.

Also, I see some wiring is unconnected (near the starter motor).

Re: Suzuki GS150R


Thank you for your detailed reply. helped a lot.

yes, oil is leaking from both started motor seal and magneto's wire, Will keep an eye on the oil level.


One more question..

How to detect engine oil burning issue?? Last time some local mechanic warned that engine is burning oil by listening to engine sound itself.

I doubted it because , neither i see any white smoke coming while revving at high RPM nor i observed any oily residue inside silencer.

Is there any other way to confirm it??

Re: Suzuki GS150R

Blue-ish/white smoke and oil in the tip of the silencer - you already mentioned it. And in most cases, the spark plug would be oil-fouled. How much oil are you able to drain, say after atleast 3000 kms -> this should be around 900 mL to 1L. It is possible for an experienced mechanic to say whether piston is worn out just by listening to it - the manual itself says in the troubleshooting section that excess noise is one of the signs of worn piston rings/top-end - but other signs/symptoms should support it.

My GS 150R has a excess oil burning issue

Got a 2013 GS 150R. Odometer reading is 19200 km.

Got 2 issues with the bike

1) Been using semi-synthetic oil for the past 10k km.
What I see is that the bike is burning excess oil- the oil level dips to the minimum level by 1200-1500km after an oil change.
Showed it to a mechanic and was told it was a bore issue.

2) Since 7k km, there are excess vibrations. Was told by the service station that this is
because of the counter crankshaft/balancer


I will be taking it to the service centre tomorrow. Any suggestions on whether it is worth it to
have the engine opened up on this bike and have work done?

If I do get work done on this bike, which Suzuki showroom should I trust?

TIA for your suggestions.

Re: My GS 150R has a excess oil burning issue

Hi ! Replies inline.

Re: Suzuki GS150R

The accelerator cable and clutch.
39k before the service and 1 more since.

Re: Suzuki GS150R

How many Kms did your vehicle Clock? If it is less than 50K, don't worry.
If you are a sedate rider and you ride on highways more. You need not consider your mechanic inputs until 60K or 70K.

They just need to open engines for money. Their sole existence in shops is to open engines. So, they try to push you. My mech pushed me to change engine components at 20K. Now it has crossed 51K and still has no issues. They just want to screw good vehicles and make money.

Try to do a engine flush with oil. When you replace oil next time, try to replace with a cheaper 200/- branded oil. Run it for 150-200 KM and then drain it and fill it with good one. All engines have a reserve oil which cannot be changed during regular services. Such a flush helps in getting rid of oil fluids in engine. This should decrease noise. but highly depends on vehicle.

Re: Suzuki GS150R

2 weeks ago, got my rear shock absorbers replaced to that of Apache's - cost me ~ 3400K. Ride experience, well - the level 3 setting on the apache's shock's feel a bit more stiffer than that of stock GS. I have set it to the 2nd level from softest setting and that has increased the height by a slight amount, ride is a lot better than the leaking GS shocks, but im not able to see a big difference from new GS shocks. The installation was straight forward and perfect fit. I would have preferred the golden colored ones, but they were not in stock.




Also i replaced my 2.5 yr old "throttle assist" with a rubber version bought from aliexpress

The old one slowly developed tear and inhibits function, so i tried to buy a similar kind. The one bought from snapdeal was for around 250 rupees. I bought a cheap one for less than a dollar from aliexpress, and it was cheap and stiff - broke on the second day and i got a refund.

This one has a smaller width, but functions the same way. Useful on highways when there is no frequent stopping.

Re: Suzuki GS150R

Hi folks
Changed the clutch plates and pressure plates of my 2009 GS today after 48k on the odo. There was no sign of burning but they were simply worn out quite a bit. And yeah clutch casing and parts inside were as good as new there wasn't any varnish built up. Total expense 1300 including fitting.

Re: Suzuki GS150R

Purchased Michelin Sirac Street for Front. Got an offer for 1300. New MRF Zapper was 1600. The current MRF one is good for another 10-15K Kms but another old splendor in the family badly needed a tire change. I will donate the current Zapper to the Splendor.

No much updates as bike is parked in my room because of a expired insurance and has hardly done 300 kms in last six months. I switch on the bike and run it for 4 to 5 Kms every week on the main stand. Engine cooling is taken care by a pedestal fan

Petrol is half way mark and the color has changed. Afraid it may start rusting inside the tank. Any ideas are welcome.

Re: My GS 150R has a excess oil burning issue

Hi ashwant.r,

Thank you for the reply

I started using semi-synthetic (MAK-4T) because excess vibrations had started by 6k kms. The service centre
told me there is less oil and gear shifting was quite hard. With semi-synthetic, vibrations reduced and
gear shifting became much easier.

However, after 5-6 oil changes, what I observe is that this bike burns excess oil.

I do 95 % of the riding in the city where it does exceed 6k RPM and 60-70km/hr speeds.

I bought this bike (May 2013 model) second-hand at 3500km ODO reading in Nov 2013.

I will ask the service centre to do a compression test. Let me see the results after that.

I understand that the 150R has a poor resale value but am not sure what alternative bike
can I go for which is quite similar to this (not interested in the Unicorn). If I can get the
repairs done for this bike within Rs 10K, I will am OK with it.

I should have specified my location, Bangalore. Any recommended service stations here?
(if not, could you ask your contact at SMK which of their counterparts in bangalore can they
recommend?)

TIA
