Re: Suzuki GS150R

Anybody here experienced excessive engine oil reduction?

I changed oil filter and filled new 1ltr Gulf Pride 4T plus @36000Km. Yesterday @38,461Km I noticed the oil level had dropped considerably low. I topped up the same brand oil till the oil level was in the middle of the min-max marks on the oil check window.

Rode the bike pretty fast @85-90kmph last night for a good 80 kmph and today morning noticed the oil level close to min mark.

I checked the smoke but its fairly colorless. Thick black smoke only the first time I pull the accelerator hard. So I can't conclude that the engine oil is burning excessively.

EDIT1: There is no oil leakage whatsoever.

Re: Suzuki GS150R

RSK,


Always fill 1100 ml of oil when changing oil filter. Filling 1L after filter change itself puts the level precariously close to minimum. I think it is normal for a 4-stroke engine to consume a bit of the oil, especially if driven at high speeds. And for GS: Checking the oil like it is given in the manual word-by-word is important - one needs to wait a full 2-3 minutes after shut down before the oil level verified.


Did you look at the spark plug? If oil is getting excessively burned inside the chamber, the plug usually will be fouled with thick, oily black deposits. Isn't black smoke for rich mixture - I think you will notice bluish-white smoke for oil leaking into the combustion chamber - like the ones those Unicorns/CBZ with worn rings make. If possible, have a friend follow you to study the smoke.


Cheers.


P.S. Mine hit 18000 kms today. 3 years old. My new year resolution will be to ultilize my GS more. One of the dealers near my home said GS is still in production and can be booked - he even had a Candy Antares Red on display and told me a refreshed one was coming next year. I wonder how you guys clean the fabric-type air filter - no amount of pressurized air cleans it effectively (I can still see blackish grey dirt sticking to the 'paper' element inside). Am thinking of changing over to Apache's foam filter. Lets see.

Re: Suzuki GS150R

I think manual says otherwise. 1L on filter change and 0.9lt without filter change. Also the gear box has 1Lt embossed on it.
BTW I checked oil level after leaving bike off overnight.
I'll check the level on next oil drain though how much oil it takes to fill to max.

Spark plug looked okay at the terminals. Only a bit of soot at the base at the end of threading. It went off with just a cloth wipe. BTW I'm going to switch Iridium plug today. Just bought it in afternoon.

Regarding smoke thick black smoke is only when I accelerate hard the first time. The subsequent attempts smoke is pretty much clear. Neither blue nor whites observed. I checked my-self sitting besides the exhaust while the bike was at standstill.

Cheers to that

Re: Suzuki GS150R

I can confirm about the manual saying 0.9l during normal oil change and the full 1.0l when changing filter as well. Did the latter around 2K km back with Shell Ultra FS and the bike is going strong. Might drain it after the next 1K km.
[MENTION=33190]ashwanth.r[/MENTION], congos on that. Mine crossed 16K km yesterday. Bought it when ODO was at 7.5K. First anniversary of purchase is a month away, so expecting to clock 9K km or thereabouts at the end of the first year of ownership.

Re: Suzuki GS150R

@rsk_kelkar and @eternoMind ,

We had discussed this before:






Workshop Manual says 1100 ml for filter change.

Then why the error - usually *owner's* manuals are just cut-copy-paste except those sections that are specific to a model. May be its a typo/pasting error.


AFAIK, that refers to the quantity required without filter change. For Gixxer, it is 850 on the engine but SVCs fill up 950 ml for oil and filter change.


The full sight glass should be fully covered with oil if left overnight on a fairly level surface. If no, the level is low. Drained oil is slightly over 1000 ml - I know this because when I transfer the used oil to the old container, it comes almost up to the brim (1L oil in a sealed container is never up to the brim).


NGK ? Model number please - I too would like to change.


I still don't think you bike is drinking oil/worn rings. <40K is too low for a Suzuki to have worn rings (But if it was an Unicorn I would have asked you to check with SVC ). But I dont have an explanation for black smoke - PSR sir once told it was due to rich mixture, which again could be caused with a clogged air filter.

Thank you RSK and eternoMind ! RSK has done double my mileage in half my time!

Re: Suzuki GS150R

Wow, thats great. I still have "Read entire Ownership thread page by page" in my to do list. There is so much more to find out

NGK CR7HIX. Haven't noticed big difference as yet may be just marginally better. [MENTION=46210]punarvasu[/MENTION] had mentioned email address here where you can order one. I bought it in a local accessories shop though.
[MENTION=28044]Maestro[/MENTION] just saw your signature while answering [MENTION=33190]ashwanth.r[/MENTION] about SaddleSore. Didn't know you were the first to complete SaddleSore on GS150R. I only knew about this one. I am planning to attempt 1600K this Feb or March.

I don't see this as a problem really as far as its only on first hard turn of acc. Just a google search yielded me this

Re: Suzuki GS150R

Hello Frenz,

I have a 2014 model GS150R (red n black).

Done 30,000 kms now. In between few service I missed. Every 2000 kms it is hard to give it for servicing. A big problem which I face using this bike.
Last service, the SA told me that oil level was very less and they observed white smoke on initial start. He said this might be an indication of engine work. .

He said we will monitor in next service and take a call. White smoke is not there when the bike is running.

Also, I would like to know what is the ideal tyre pressure with pillion. I could not see it in the booklet. I normally keep 25 infront and 35 in the back. Is this correct psi pressure?

Please advise. I run close to 100 kms daily (Single way - 50kms). I get mileage of 40 km/l and ride in the speeds 80-90 kmph and at times 100

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

Also, grip levels are coming down daily. I am planning to change the front and back tire before monsoon sets in.
Any good tyre suggestions?? Is it ok to go ahead and get a tubeless tire?

Re: Suzuki GS150R

If there is no colored smoke while bike is running I wouldn't worry about this one.

Cold tyre pressure front:25, rear 29 (no pillion) 33 (pillion) as per sticker on the swing arm. I think manual says 28 & 32 resptly for rear tyres though.

I'm running on stock approx 39k km and a change is due before monsoon this year, specially front. I was thinking of Zapper FQ & Q/C for my sane riding style and heavy monsoons in Goa, haven't put much thought in it though.

Re: Suzuki GS150R

1. When you start the cold-engine (parking more than 3 hours), let it idle for a minute.
2. ride first 10-15 minutes or 10 kms around 4k RPM or lower.

(as rsk_kelkar points out)For better grip than stock you can go for MRF Zapper Q(rear) and FQ(front) both TubeType; usable life will be lesser than that of stock.

Re: Suzuki GS150R

Hey Guys, My GS tank's surface inside the fuel cap has rusted and now the tank's surface above has started catching rust as shown in the images. Any solution to the above? Reply and suggestions are requested. Thanks

Re: Suzuki GS150R

Is the bike still under warranty ?

If yes, SVC will mostly replace this free of cost. If no, you could still write to Suzuki who as a goodwill gesture replaced some rusting fuel tanks (initial batches) even post warranty period.

Why am I seeing so many scratches near/on the sticker - I thought only mine had those. If you have the habit of keeping your helmet on the fuel tank, make sure the tank doesn't get scratched with the metal things on the helmet's safety band/strap.

I occasionally spray Zorrick or WD-40 inside that area.

Re: Suzuki GS150R

You should sure ask for a replacement. If not, make sure your water drain hole is not clogged. Pour some water in this hole and see if it is draining out from underneath (Being absolutely careful not to pour a single drop of water in fuel tank).

Also I see the rubber plug is bent or damaged. I am not sure what it is, may be a fuel overflow or just to keep fuel tank pressure from building up due to fuel vapors on a hot day. May be place it correctly facing up?


Scratches on the tank surface are such a turn off for me. I tried my best to not let the tank get scratched but somehow they just get there :P.

Re: Suzuki GS150R

Since an airtight fuel tank won't allow petrol to flow to carb, this "breather" is necessary. There are 3 rubber hoses below the tank - one for draining rain water. Other 2 (2 so that one will work in case 1 fails) for supplying air to this mechanism. If I understand it correctly, air flows this way: 2 tubes below tank > the bent rubber in the picture > fuel tank cap > fuel tank. My drain hose doesn't drain properly too. Will try to rectify when I remove tank in future for valve adjustment - usually it will be a bent/clogged hose.

If the bent breather can't be un-bent, then it might be necessary to replace the tank lid as a kit (Ask SVC if the rubber part alone can be replaced) especially if the bike starts to runs as if its short of breath.

Re: Suzuki GS150R

As far as I remember these 2 breather hoses at the bottom join together with sort of a "Y" joint and this goes to tank breather hole.

Mine was clogged too due to a bend somewhere. As a result water was accumulating and on front braking used to ooze out of the tank cap. This may be the primary cause of the internal rusting.

BTW You don't need to remove the tank for valve adjustment provided you have the right tools. Just a right size ratchet did it for me.

Re: Suzuki GS150R

Thanks for your reply ashwanth.r The bike is not under warranty. Rain water got accumulated during the last monsoon inside the tank and it caused rusting. The drain pipe was clogged due to which water got accumulated. I took it to a local mechanic who cleansed the drain pipe. Should I write to Suzuki India directly or take it to the SVC?

Thanks for your reply rsk_kelkar. Rain water got accumulated during the last monsoon inside the tank and it caused rusting. The drain pipe was clogged due to which water got accumulated. I took it to a local mechanic who cleansed the drain pipe. Now the water gets drained. There are no major scratches on the tank near the sticker. It must be the reflections of somethings which has come while taking the picture which you are seeing. The rubber plug is for air flow I guess..
