Re: Suzuki GS150R

But still I want to try full synthetic once.

Whats the difference between 10w40 and 20w50 ??

Re: Suzuki GS150R

I'm on Shell Advance AX7 10w40 at the moment. Congratulations in advance, Duke390 is everything GS150R is not & vice versa. They complement each other.Motul 7100 4T 10W-40 is fully synthetic too. Thread Engine Oils - Page 844 is completely about Engine-Oils. You should get sufficinet info about Oil grades/specs in/out/over there.

Re: Suzuki GS150R

gs is gs and i think evn i own 390 gs will give mi diferent pleasure than duke

Re: Suzuki GS150R

Hi guys,

Pls take a look my 4 year, 15k kms old GS' rear tyre and suggest if I should replace the tyre.

The tyre has seen 3 tube changes and around 10 punctures. Also have 3 patches on the inside of tyre.
The tread is pretty ok but look at all the holes the puncture has created.

Tell me if a tube tyre like Sirac Street or a tubeless Zapper Y would help?
Roads I travel are in a mess.

This friend of mine said the tyre has become too soft to handle the smallest of particles and that is causing punctures.
Tyre pressure from Day 1 has been 25/29 or 33

My Night Fury - The GS150R



Hey all, I already posted my test ride and selection process of Suzuki GS150R in another thread even before opening a new thread, out of curiosity.
Let me not go into that again. The following link would tell that. Let me share my ownership experience with my bike so far.


All I needed was a comfortable bike and GS serves the purpose quite well.
The first service has been done and the gear shift has become a lot smoother after that.
I felt as if the engine was over heating. I could feel some heat near my legs and there was also a burning smell when I park the bike after riding it for more than 5 kms. But, after the engine oil and oil filter change during the first service, the overheating problem has reduced (though not completely resolved). May be the wearing off the new engine parts during run-in period is causing this. Will wait and see if it reduces still more.

The engine is pretty smooth except for 3-4K range. Only at this range the engine tends to get noisy. The handlebar is pretty light and aids easy maneuverability in city traffic, although not as light as an FZ. The switchgear quality and feel is good. The dual horn setup is too good (neither shrill nor lousy). I feel that the headlight brightness could be somewhat better. The roadgrip is very good, thanks to the MRF rubber, but the braking could have a bit more bite. Not that the brakes are inadequate but it could have been better.

I have now started to stretch my 'toothless' till 6500RPM occasionally, and man.. it is perfectly stable even at the speeds of 90kmph (courtesy it's weight).
I had a doubt before buying it.."Will I be able to manage this heavy beast within the city?". It's been more than a month since I bought it and I started to get along with my beast so well now.

I have covered around 1800kms so far and believe me, I am completely bowled over the suspension of GS. It puts a grin in my face whenever it takes the potholes aplomb. I seriously did not expect such a pliant and comfortable ride from the gas charged shocks. Of course, it isn't a Punto to have both plush ride and excellent handling. The handling takes a small hit since the main focus of GS is on the ride comfort and straight line stability rather than sharp handling. Since I am a sedate rider, I did not want the handling to be sharp at the cost of the ride quality.

I am yet to push it to the north of 7000RPM. Will probably do that next week and see how it fares. I actually don't like to do a quick sprint on city roads. So, I would rather take it out on the highway next weekend and stretch it gradually.





Update:
As I mentioned earlier, the engine tends to become noisy (sounds like a knocking sound) between 3K-4K RPM range. The service guys say that this sound is expected from GS because of the engine balancer. I also rode another GS which also had this weird knocking sound. The bike is pretty smooth except for this sound. Anybody else facing such abnormal sound? I heard that even bikes like FZ has an engine balancer. So, I doubt if this is the real cause for the sound. The service supervisor says that GS has a double balancer. Is it true?

Anyways, I do not regret one bit on buying a GS. Yes, it isn't sporty as an Apache or eye-catchy as an FZ, but it does it's job absolutely perfect with exceptional ride quality and very good mileage, plus a number of people asking about the bike in signals and petrol pumps. I didn't expect it to be a head turner, but surprisingly it is may be because of less number of GS on road.

Re: Suzuki GS150R

The tyre looks to have been chewed up pretty well by punctures :P Time to get it replaced. I used a CEAT Vertigo Sport for my GS150R's rear tyre and it ran for well over 21k kms and suffered only two punctures. It's a good tyre that can be used with tube or as a tubeless (I ran it as a tubeless). I am currently using Michelin Sirac Street on both front and rear. Have run them through just 1000kms till now and they seem good. Happy choosing.

Re: Suzuki GS150R

@samcan123, Nice write-up. What knocking sound? Can you post a youtube video of the sound if possible. AFAIK, the engine balancer doesn't make any funny sounds. SVC guys have their own sense of humour - I once asked why there is a tik-tik sound from the silencer and i got "It is hot oil dripping from the filter back to the engine and this has been taken care of in the new GS".

Re: Suzuki GS150R

I would try capturing the sound and post it this weekend. It actually sounds similar to the knocking sound we usually hear when we ride on a higher gear in slower speeds and the engine is not able to pull the bike. It is evident between 3K-4K rpm and then gradually fades away.
I had complained this issue in 3 different service centres in Chennai - Avenue Suzuki (worst customer experience as far as bike service and customer service is concerned), Pramaan Suzuki and ABT Suzuki. All the svc centres say that the sound is expected in GS and it is not an abnormal sound. My trustworthy mechanic, though has not worked on a GS before, with his many years of experience says that the sound seems to be due to high compression. He says that it'll not affect the engine life but the sound may be there forever if it's not rectified.

I already faced the hazzle of going back and forth between difference svc centres reporting the problem. I did not want to spoil my peace of mind by trying to ask the svc guys sort out the issue which they say is normal. So, as of now, I am trying to ignore the sound and enjoy the ride.

And yes, the service technicians have their own imaginations. The svc technician in Avenue Suzuki told me that the sound is nothing but the silencer beat. He compared Unicorn and Apache and said that the newer versions of GS has an open mouth silencer like Apache and thus it is louder . They consider the customers to be so naive. I just left the place since I thought there was no point in explaining him that it's not the sound from the silencer but from the engine .

Re: Suzuki GS150R

Guys please suggest which one to go for my gs150r:

10W40 or 20W50

Re: Suzuki GS150R

Go for the one which is mentioned in the User Manual.

Re: Suzuki GS150R

20W40 is recommended in the manual.

The available choices in motul 7100 are 10W40 or 20W50.

Please suggest.

Re: Suzuki GS150R

you can go for 10w40. 10 is the rating of the oil for cold start and 50 is the rating of the oil for its viscosity in higher temperature if your bike manual says 20w40 then you may go for 10w4o. No harm in it. And anyways 7100 is fully synthetic.

----consecutive posts auto-merged-----

20 W 40 as a rating is :

20 - the Viscosity index rating of the oil at 0degC
40 - the Viscosity index rating of the oil at 100degC

the higher the VI rating , the thicker the oil is , less it flows - not ideal for pumping it at low temp but good for sticking to walls or at high temp where a thin oil will become something like water

So 20W40 means the oil is having a VI rating of 20 at 0C while at 100C it thins only to the level that a 40Weight oil would thin to .

Thus 20W50 is relatively speaking thicker at 100C than a 20W40.

If your engine needs an oil that is at least as thick as 40 at 100C , you can use a bit thicker one - W50 ..even if its not ideal - because its heavier than required and tougher to pump it .

But using a less than recommended oil like a W30 means its not thick enough at 100C to stick to walls and might not be lubing the internals well enough .
