My mech told me not to change air filter and spark plug and telling they are fine no need to replace now as i told him as per manual we have to replace...
Mine 11800km on odo , shall i change both? on next service?

Abdul Bhai it's a small problem, no need to change air filter and spark plug. Gulf 4T is a very good oil so thats not a problem either. Its just because of this weather.

oops , my query is not related with engine oil and cold start and spark plug airfilter........

i just ask people on what KM we have to change spark plug and airfilter...whether stick to manual(8000km for spark plug,12000km for air filter) or leave to mechanic choice.....
bcos i exceed the limit for spark plug replace and nearing the limit 12000km for airfilter as my odo now 11900km
thanx

@ Abdul Bhai

My bad i thought you were asking for replacement due to cold start problem

. Does this spark plug only last 8K

? i thought it to last more than that. Air filter is a cheap component rite

. And what about oil filter have you changed it at 8K kms after first service?

Thanks to you I read the periodic maintenance and lubrication schedule manual thoroughly

After Some posting of knocking issues time to praise the beast. Now I thought my GS was noisy with knocking sound,So after being so busy went to meet my friend who has apache and who wanted to ride the GS. First impressions Before start "Yaar it looks Good in blue And it is massive". After that he wanted to have a ride,gave him the keys he started the engine he told so silent. After a brief ride he was praises for the Ride comfort and off course the Console. As usual he has been riding the RTR180 so he complained about the rear discs.

p.s Today was driving in very cool conditions in the morning it was fun to ride.

I just read something in the pulsar 220 dtsi ownership thread and realized i might have a similar problem..

Firstly the problem is that my gear shifts aren't very smooth in the 1st 2nd and 3rd gears.. example, sometimes while shifting from 1st to 2nd it makes a loud thud noise if rpm is around 5k, sometimes it just goes to neutral and goes to 2nd only if i leave the clutch, press again and then shift..
sometimes it gets stuck in neutral and doesnt shift to 1st until i move the bike a little..(at signals especially)

Anyway in the P220 thread it was written that when the bike is in center stand(with back wheel not touching the ground) and bike turned on, in 1st gear with clutch fully pressed, the wheel should not rotate. if it does then the engine is still engaged which can cause the hard shifts and reduce life of clutch plate..

Have any of you tried this experiment before ??
Does the back wheel turn in the above case and should i get this checked at the service center ??

That means the clutch cable needs to be loosened.
Within a couple of days of my purchase I realized this problem in my gearshifts..........
took the bike to my family mechanic,he identified the problem,loosened the clutch cable and the gearshift is so smooth and effortless that it sometimes shifts without clutch too at lower rpms !!!!!

Yes its the right test and so,try to loosen the clutch cable a bit by a good mechanic.The clutch cable should be flexible and not too tight.Factory finished GSRs and SVC serviced GSRs both would have tightened Clutch cables,loosen them.GSRs shifts are one of the best in the industry.....in league of Unicorn I say insistently.

my writing is bad

thats why u misunderstood......As per my SC mechanic says me don't change spark plug until there is problem(the real case is no stock

)...In my previous bike pulsar u know that they have 2 spark plug....on one service i told my pulsar mech to clean both.. when he open he found left side sparkplug is completly broken

no firing for that one, but still bike run with 1 spark plug

, i changed that broken at 10000km, then changed the next one at 20,000km.
I think its better to change at atleast at 15000km for our Gs150R...
ya i change oil filter every alternate oil change

Is anybody in these thread have suzuki baleno 1600cc , i came to know one of the wheel bearing gone for my car ,when ask maruti dealer he quote Rs 5000 for single piece ,when i asked outside like MY TVS they quote Rs 1800
why such difference ? May be Rs 5000 is japanese one and Rs 1800 is SKF indian one....please clarify if anyone knows abt it Thanks....

Just did that test and even with full clutch rear wheel was turning. Actually I have noted this problem but didnt think it as a problem, just as i shift to first gear the bike suddenly moves a little. I thought the problem is inherent to all GS. I will consult a local mechanic and give update.

What exactly do you mean by loosening the clutch cable? Did you mean to increase the play of clutch. After every service clutch is tightened I loosen it everytime since its very difficult to ride with a tight clutch.

Thats not a problem

, since you mentioned changing filter and plug under cold start problem I just assumed its because of the starting problem

. I think the replacement mentioned in the manual is always the extreme value and it should not be prolonged further. For eg: oil change interval is 4000 kms. But almost everyone changes oil around 2 K. The stock spark plug is NGK, so it may last longer. Its really sad that NGK is not providing iridium spark plugs for our GS

what bike u currently have?....when we discuss oil issues , we forgot one thing, i don't know abt rest of the bikes, but GS150R comes with suzuki jet cooling system(SJCS) not in other bikes i hope so atleast for 150CC till 220cc..
Is that thing makes all sort of roughness issue or knocking etc ...i have doubt
just want to clarify
My mech while changing oil last time (gulf 4t Plus) ,did'nt add extra 100ml as i changed oil filter too , but he add 10ml to filter(in hole), then rest 990ml to oil tank...
shall i add myself 100ml? extra?
The reason he told me is while opening engine only we need another 100ml or more.. is it true?

I currently own both bikes pulsar 180 ug3 as well as gs150r. Yes u need to add that 100 ml extra when oil filter is opened per Suzuki. Jet cooling is a boon for our GS coz oil need not be picked up by the piston motion or crank throw etc, it is directly jetted to back of piston, one of the trademark feature of this bike, it translates to better lubrication no doubt. This engine tightening up after a 30 minute city ride has happened to me once immediately after my 1st service on way to home, i was really upset as to what had happnd. Chekd the bill it said 1 liter has been put with filter change etc. Of course i refilled it that evening...

Also point to note is some amount of oil (400 to 500 cc) will be in circulation around the valves cools the top part of the engine...so the remaining oil passively lubricates the gears and clutch bell etc..means the oil is shared...if u have 100 ml less oil that translates to slight shortage in the passive lubrication zone and as the internal pump does its bit to pick up oil and throw it for lubrication around the engine

Bro, if you know about the working of jet cooling system please post a detailed explanation.

This has happened to almost everyone. But with more Km on ODO this roughness will go away. My personal opinion is to change oil by ourselves. Buy a 1 L can of any oil of 20W40 grade and change it by a local mechanic. The oil used in service centres is very poor in quality.

1 litre without changing filter
and 1.4 litre if you open the engine.

While filling 1 litre and not changing the oil filter, i noticed that the oil level comes exactly between the E and F lines.
May be another 50ml would bring the level a bit higher near F line but since i have to buy a whole bottle i just fill the 1 litre and use it.

If your bike's oil level is near the E line then you need to add some oil, otherwise just use it like that.

Does your bike have a oil indicating window ? (pulsar i meant)
If yes could you tell the oil level in both your bikes with the extra oil ?
(like does it cross the F line by a big margin ?

Excess oil does have bad effects buddy.
For one, there will be a damping effect on the motion of piston due to increased resistance to motion by the extra oil, which translates to low power and mileage..

yes, pulsar has the oil window, it goes up by about say 4-5 mm for 400 ml added above F( i can see clearance bubble at the top of circular glass). True i agree about damping, may be after 8k..for lower rpms lugging around in the city does not make much of a difference in my ride tho except being smoother and vibes less

Yes.......and not only that,the clutch cable is linked by a screw mechanism to the transmission box,loosen it a bit too.I now feel that I should have observed a bit more carefully what the mech did to get rid of the problem.Maybe I could have guided better

Hmm..........I got it now........thats why the Suzuki engine cools down so fast !!!!!
The engine points mentioned in the Wiki article are the points at which where the GSR engine never heats up !!!! true
Eg.top of the combustion chamber.:
On the Zeus.......this place was a scorcher to touch after a ride.
on the GSR..........anyone can touch that place even after a very long ride.

Wow Suzuki,you gave GSR all the best things you have got.........no doubt even the Honda biased magazines are now praising you !!! GSR is really a very high tech bike then !!!!
