Re: Suzuki GS150R

A bit late for a mineral?
Mobil Delvac™ Super 1300 15W-40
Viscosity Index, ASTM D 2270 : 99


Interesting design, bypass is better than engine dry-run then seize. I can't understand it though.

It has to be sludge since you've seen cleaner, shiny aluminum surface during previous DIY. Did you try to wipe it out with a clean cloth?
The brownish deposit looks like grease or wax, which is solid at room(ambient) temperatures but melts at engine-operating-temp.

Rubber usually expands when subjected to heat, and is durable in colder temps. I don't know what caused the wearing of that O-Ring.

How is the response from engine between peak-torque-rpm and peak-power-rpm after replacing mobil with motul mineral?

Re: Suzuki GS150R

1. Yes Ji, I had taken the mineral oil too far. Though Suzuki recommends a 4000 km oil change interval (and Hero 6000 kms for Karizma-R IIRC), we know it might be a joke. Am here after going to change a mineral every 2500-3000 kms.

2. I think some motorcycles like Yamaha FZ series have the bypass located on the filter cover itself.

3. I didn't see any silvery aluminum (It was visible in Sparkot's oil change photos). This was my second filter change - so, I really don't know the color of the internals. As I told before, there was a bit of black paint too - engine crankcase paint. The brownish/black material had a 'matt finish' but was smooth to touch. Yes, I wiped the oil filter compartment.

Below: See the part of the oil filter cover that comes in contact with oil - It was silvery silver !





4. Yes you are right, rubber usually swells - but this one sandwiched tightly between the filter and the inlet lost its girth a little.

5. My usual cruising speed is 60-70 kmph - Will I hit peak-power and peak torque in this speed range? Initial Impressions of Motul 4T 3000 Plus: Felt slightly heavier and the gear shifts were obviously smoother - especially downshifts. I don't know if there will be much difference from the previous equally heavy 15W-40 Delvac.

6. Some spares to be replaced in the coming days, got a SGP/Castrol 20W-40 too (I love Mineral oils ). Other SGP oils include an Idemitsu 10W-40 "Synthetic" for Gixxer and Motul-Suzuki 10W-40 for Gixxer. Not all SVC have both Motul and Idemitsu.

"What did you say saar, you want 2 oil filters?"




7. Below: 11 PM oil change bliss, I had dinner at 12 AM!

Re: Suzuki GS150R

Will take your advice, previously had an idea of pouring Shell Helix HX7. Semi synth,Api SN grade, low cost but dropped the idea due to fear of Clutch slipcatalytic converters. Please share your experience with Motul 20w40

Not recommended. Yes, there were some xbhpians reporting clutch slippage with this, IIRC.



See. Can you say why you want a HDEO? The only reason why some of use HDEOs is because of slightly higher ZDDP content

I thought zddp prevents wear and tear and Diesel oil is bit thicker, has better detergent to keep engine clean ,works well even under heavy load. So it may keep our engine young in long run. But dropped the plan after studying that it is bad for our catalytic cons leading to extra pollution : )


NOTE:Have you tried cleaning it?Suffering from low mileage problem since first service (850kms on ODO it was a new engine then).
Mileage calculated using reserve to reserve, Mileage Can etc.
Driving Style: SEDATE. 50-70 on highways very less clutch and brake (45kmpl) city frequent brakes and clutch (43kmpl)...Gear shifts at 4000-4500 rpm

Did you get the carb tuned at SVC or local mechanic? Are you sure there is no brake binding and chain is correct slack?

Tuned by SVC 5 times, Carb clean 2 times, tuned by me 2 times no improvement. No brake binding wheel rotates freely, Chain slack is optimum.
I doubt my Valve clearance


Will post a detailed report on Accident, Repair, and Insurance Soon.

Re: Suzuki GS150R

If at all you are still in a craze to try out a heavy duty diesel engine oil, try experimenting with an oil like Mobil Delvac 1300/1400/MX or Shell Rimula R4. Stay away from engine oils meant for petrol cars. Some will okay a dual-rated oil like Helix HX7 but it will be a headache if the clutch slips and you have to perform an unscheduled oil change.

AFAIK, HDEOs will not do magical things to our GS like completely removing vibrations, improving mileage or the smoothness that is already present. Also, there was one point which was never clarified till today - motorcycle oils might have additives (?) to deal with the stress of lubricating the gears ('shear' stress?), we don't know whether HDEOs have these additives. Also, in a motorcycle, the oil has to transfer the heat which is not the main job of the oil in an Ashok Leyland truck. That is why I was interested in Castrol CRB Mini-truck.

As P.S. Raghavan sir rightly pointed out several times, this is just an experiment and have to be done with one's own risk.

All oils contain ZDDP. Their content is the lowest possible in oils of higher rating perhaps to protect the Cat-Con. Go through the Engine Oils thread when you get time, via google by searching "xbhp HDEO" - A wealth of information is present.

All being said, I have no complaints against Mobil Delvac 1300 Super.


xxW-50 oil is a little thicker for our engine (oil pressure will be lower than optimum) while xxW-30 is literally grape juice. Suzuki recommends 20W-40 for GS and always go for a xxW-40 (10W-40 SS, 15W-40 SS or 20W-40 mineral). Okay this time, next time shift to a 20W-40 (or) if the bottle is still sealed, the shopkeeper might accept it back.

Use of 20W-50 itself will contribute to the low mileage issue.

Motul 20W-40: The oil was good. Saturday being very gusty and rainy, I was driving cautiously and the GS was struggling to maintain 65 kmph at 5000 RPM (normal with heavy winds in the direction opposite to travel).




Yes, but not with something like Kerosene. Lets see, am happy if that 'sludge' thing doesn't worsen.


For semi-aggressive acceleration and maintaining 70 kmph on 6th gear, I think one can expect 50-55 kmpl from GS. However, it does return 60-65 kmpl easily for a gentle right wrist and maintaining 60 kmph on 6th gear (4500 RPM).

The first thing that my Honda SVC did was to change the air filter, tune carb and adjust the valve clearance when I complained to them that my Eterno was returning 35 kmpl (first service after buying it second hand). Mileage then jumped to 56-60 kmpl in spite of me hitting 60 kmph on 4th gear often.

Unfortunately, am not as knowledgable (or experienced) like Punvarvasu/Sparkot. So I will keep mum for the time being instead of advising you something that am not sure of. What you are doing is right - test mileage using can-method only. Just out of curiosity - what story does the spark plug tell?

So, I understand you do all the basic DIY jobs too ?


That is fantastic, waiting.

Re: Suzuki GS150R

Atlast bought amaron pro battery 7amp beta
It was tough to buy this battery
Most of the dealers stock only 5 or 9 amp
Cost 1300
Warranty 48months

Is amaron better one than stock exide freedom
Also changed chain sprocket kit after 20.5k kms
Now the bike runs smooth like silk
Oil shell ultra fs 10w40

Re: Suzuki GS150R

Did the 7 amp battery fit into the cage without alterations ? My battery is conked as well. Yes, It is better than stock Exide !

Re: Suzuki GS150R


yes it fits without any alterations..

Re: Suzuki GS150R

The right solvent to clean out that dirt would be petrol , not kerosene . Then wait a while for the residual petrol, if any, to evaporate out .

In my humble opinion , better stick with 20w40 motorcycle oil . 20w40 is plentiful in the market, cheap and all of them are very good . 20w40 motul 3000 4T plus & gulf pride 4T plus are excellent oils . If sourcing genuine oil is a concern, can even get servo 20w40 from any petrol pump or 20w40 yamalube from yamaha service . Would be good to drain and replace oil every 3000 kilos at latest . Better for engine to run fresh cheap mineral oil than stale costly oils . I am bit over-cautious and I drop the oil by 2000 kms/ or 4-5 months, whichever occurs earlier . Never had any problems from early oil changes

ALL replaceable paper oil filter system for motorcycles have a bypass mechanism or device in case the filter becomes too clogged from dirt load . Circulating dirty oil is preferable to a seized engine any day .

Re: Suzuki GS150R

Pinaki Ji, I second you without any doubt - it was a recent realization for me that good mineral motorcycle oils are just fine. These Japanese gasoline engines doesn't really call for an oil used in Ashok Leylands . That was the reason why I used "if" and "still" in my 2 cents. I have tried 20W-40 from Servo and can say it is a good oil. I have tried original Castrol Go! (Basic 20W-40 from Castrol) too.

If am not wrong, even you tried HDEO in your Splendor - reverted back to MCOs ?

That 'sludge' might be corrosion (?) - have left it as such now. In fact when one searches the google images for "xbhp splendor", we get some pictures of the Joy/Splendor's gear assemblies (by Paul?). They have the same corrosion/sludge thing.

Re: Suzuki GS150R

But, I don't understand the mechanics here.
Assuming the filter is clogged after prolonged use, how does inflow of oil push the spring-actuated-valve against the oil current/flow?

Edit: I get it now, how spring system works. But, how the force to compress the spring is actuated/realised?

Does the filter has any provision for oil to get behind the plate pushing against the spring?

Re: Suzuki GS150R

Am not sure brother how the mechanism works on cartridge filters , my bike uses centrifugal oil filtration .

Servo has the added advantage that it's available wherever there is an Indian-Oil pump , so you can easily buy a bottle on the way on a long trip for a suddenly needed top-up for example , and there is no chance of getting spurious oil when you buy any oil from a petrol pump , very very safe .

I had it in mind but never got around to using HDEOs . There not much cost advantage in it either . Presently I have filled 10w30 Gulf Synth 4T last week only - for this winter . I use 20w40 motul or gulf in summer .

Re: Suzuki GS150R

Hi All!
Greetings from a fellow GS150r owner in Chennai.
Its been a year and 2 months since i'd bought the White GS150r and 21890ish kms on the odo. It was giving me a mileage of about 57-60 (once or twice even 62kmpl) when i used to travel from my home near avadi taking the chennai by-pass till my office at Sholinganallur everyday, thats 47 kms oneway, with avg speeds of 55-60kmph (now you know how i got that mileage).
Nowadays(for the past 6 months), i travel only around 10 kms to office due to changed residence..mileage around 55kmpl.
Been a wonderful experience riding it and few things i learnt from it and this being the first bike im using properly since ive only used bicycles till my post-graduation years
--- Learnt not to brake hard in corners and pay due respect to road conditions. Fell down once or twice due to this and was blaming the Zapper-Y tyres until i changed braking habits
--- Maybe because i have smaller hands, i used to get wrist pain in both wrists while riding long distances everyday. The entire palm used to burn! But then, by the 6th month i bought this Vheelocity crampbuster: Buy Vheelocity Vheelocity Red Crampbuster Motorcycle Throttle Control - Best online prices and reviews from shopping sites in India. I use it ONLY on the highway stretch, so i dont have any wrist or hand pain anymore
--- Also, 2 months ago i kinda played with the handlebar inclination a bit and learnt not to meddle with it anymore . It looked cooler to have the handlebar more depressed toward the rider, but it started giving me a backache, so kept it back where it was initially. Now no pain at all! not even the minor arm aches!
--- (This might be helpful to a few) The housing of the RVM on the right had its thread worn out due to abuse and i couldnt fix the mirror back..service center guys said that the entire housing (disk brake oil portion) had to be changed which would cost 2000/- plus. Local Mechanic directed me to a turning shop who finally said that it was futile to do any sort of weld and i didnt trust any other mechanics, so finally i did some jugaad and bought a clutch yoke, cut it and fixed it to the handlebar, job done in 130 rupees.
Later found that the chinese not only had such an item already, but also sold it in different colors!!..Universal 9mm Stud Motorcycle Rearview Mirror Mount Seat Aluminum Alloy Clamp In Stock-in Side Mirrors & Accessories from Automobiles & Motorcycles on Aliexpress.com | Alibaba Group

Thats why Make in India is Important!

okay.. enough essay writing.. time for the help required section:

Night riding on highway is getting difficult. especially in Rains. I would like to know what upgrade i can do to the headlights. Im trying to avoid the rewiring method (primarily because i dont know where/whom to trust to do it in chennai).
I'm counting on LED's and hope to make them atleast look legal for the road. Since our bike uses 35W lamp, is it possible to use a 30W LED(something like Cree LED Motorcycle High LOW Beam Head Light Lamp Bulb 30 Watt | eBay) in its place without any rewiring. will it help? (sorry if it is a noob^noobest question.my engineering knowledge is going nowhere atm). Could someone please direct me to links/images where the stock headlight is taken apart so that i can get some idea?

will something which is advertised here work?: like this or This one.
Or please suggest some method that could get me around 1800 lumens on high beam. Please help.

And could folks in Chennai please direct me to the best service center in the city?.. Tried SMK, porur for the initial 5-6 services and then due to close proximity, have been giving to AVISH near ambattur. Is ABT better than SMK?

Lastly..Here's my Bike... (errr.. photoshopped )

Re: Suzuki GS150R

Hi,

I purchased GS 150 R, three months back in Bangalore , and done 2400 kms so far and is due for second service. Yesterday the accelerator cable got cut and i was stranded in the middle of the road. When i checked with the service centre, they say the cable is not under warranty. To me, though this is a wear and tear item, the bike has done just around 2k kms, and is not justified to get the customer pay for this. This also disappoints me as I had high aspirations on the quality of this bike, while buying it, ignoring Unicorn, CBZ and all others!. Could some one help if i could get this done under warranty

Re: Suzuki GS150R

Hello friends,

Small update: I am still in Mumbai post my bangalore to Mumbai road trip. Bike was due for 7th paid service on 23rd November 2015, so, I went to "Riya Suzuki" in Mulund, Mumbai.

As usual, I prefer to be around the motorbike (GS150r) when it is being worked on, today was no different. I was shocked to learn following:
1) chain cleaning and lubrication was done without even opening the chain cover. Bill said Rs 150 for this job.
2) brake pads were not cleaned, nor checked
3) greasing and various lubrications was carried out BEFORE water washing
4) nothing was done in the name of battery check

I informed service manager about all this. He asked the mechanic, mechanic said "things feel ok, so, no need to check". I made him carry out checks properly, it took another 2 hours after he had initially reported that servicing is complete and bike is ready.

Additionally, I noticed that they made the bill based on price list of gixxer parts/oil. When I mentioned this, the lady at the bill counter started arguing. I mentioned that this is not normal price and this is not the first time I am getting the motorbike serviced. Later on, the manager intervened and she changed the bill with "GS150r" spares. Price difference between the two bills was around Rs 180.

so, friends, please be careful and keep above things in mind. Maybe these are very basic things and all of you already know this, but to be honest, I was very disappointed to see this kind of workmanship and attitude from the biggest Riya Suzuki outlet in Mumbai. It was almost like I had to watch over the entire process just to make sure that the most basic of jobs was done as it should be...

finally, 2 pics after today's servicing, I didn't do any work, but felt exhausted anyways trying to get the job done! Lol...

3 weeks remaining for the 1st anniversary 8150 kms on odo as of today, average mileage over last one year with normal petrol 53-54kmpl! I'm glad I chose Gs over the other 150cc bikes, it's a wonderful motorbike...really unfortunate/sad very few of us (motorcyclists) know it's true worth!

Re: Suzuki GS150R

Now, imagine the service quality in normal SVCs in your absence!

Customers are taken for granted as dumb by most manufacturers; and they're in fact right ;-)

Suzuki seems to be struggling with profit margin with SVCs or SVCs are becoming greedy.
