The eco or power modes do not make any difference in the performance or mileage of the bike. The blinking light is a reminding indicator, warning you to limit the speed or shift to the next higher gear to avoid wasting of fuel and it is not like the engine management system, Suzuki Drive Mode Selector (S-DMS) in Hayabusa which is not to limit the usage of fuel but to limit the power output of the bike.

Someone, extremely proud of his GS claimed that the its modes are like the A B and C modes of Hayabusa and claimed that there is a third mode which Suzuki has not even dreamt and named it GOD mode – poor god. So it is better to not waste time and energy to find out the difference in the performance of the bike in these modes. All the modes – including GOD – give the same result. But changing the modes may perhaps give a psychological effect in your driving style which may bring some satisfaction like that you get when you replace the engine oil with that you like most or when you use the brand of petrol you like most. All of us know that all the companies collect petrol from the same refinery and do not add anything to it except in branded ones, but believe that some brands are better than the other.


Agustine,

It is difficult for a person like you to understand what karacharana… is. It is a mantra chanted in black magic and exorcism which was widely used throughout the world but in some Arabian countries which have far better ones. Its symbol is cross. (You don’t misunderstand; it is the inverted cross).

The recorded first wide usage of it in India was in Goa, then Nagaland and now in Orissa, Manipur, Bihar, Karnataka, Tamil Nadu and almost all our tribal areas.

Before importing to our country, the plague was widely spread in the North and South American countries and came to us mainly through Calcutta. Whenever you get time, try to know something about the history of mankind, emphasising the history of dark ages. Seek and you may get books in Tamil or simple English.

To know what the greatness of humanity is, read the book ‘Les Miserables’ of Victor Hugo. The next one I recommend is his own ‘The Hunchback of Notre-Dame’.

Both these books translated to almost all Indian languages including Tamil. I assure that both are not against your beliefs and what you are taught to believe.

Diabolically, vishnu.

Guys I have three queries i would like to make regarding the GS..

1. The 3 modes that we have - ECO, PWR and BLANK..what exactly are these..i know that the white light blinks at diff RPM..but other than that is there any change? There is no FI in the bike that the amount of fuel being sent into engine can change..i have personally not tried any mode other than the ECO yet..but i would like to know the differences if any..

2. From my understanding, Increase in Weight = Increase in power required, Increase in Power Reqd = Increase in Fuel consumption..So..How does a bike that has a full tank give more mileage than a bike with say 5 lts of petrol..is the fuel reqd to compensate for increase in power greater than evaporation caused by keeping the tank partially empty??

3. Do all bikes have resonance frequency..the GS is at 3500k to 4000k..but my brother's unicorn doesnt seem to have range like that..is this a constant or something only the GS faces???

@KIRTIMANNAN: Please read Vishnukmd's comments above your post, he as explained it quite beautifully that the different modes are mere indicators to help you to get the best fuel efficiency out of your bike one way or the other. They do not change any kind of fuel flow to the engine

i think vishnu's demon prayers are giving him powers to read peoples mind and post in advance.....now i am spooked...

If I remember correctly, even TVS victor has a power and economy indicator wherein a light blinks automatically at appropriate rpms......it isnt done by selecting modes on a console like our GS. If the modes on the GS were just blinking lights, there would be no need for selecting them manually. There definitely is a difference though nothing drastic like on the hayabusa or gsxr or any superbike.
+ you need to switch off the engine to change modes.....If it was just blinking lights, ther could have just been a hibeam\lowbeam like alternating switch for it.


@kirtimannan: thats 3 queries.

q1: Try them out personally.
q2: I dont know....same confusion(some thing related to liquid vapour equilibrium)
q3: I initially felt that resonance at those rpms too. My bike has run for 6 months and I dont notice it anymore.


@satellite.kid: Now, how would you support a statement thats not even related to your bike?

i agree with u @2strokerama the manual says n many people on the forum are of the opinion that it is just an indication to change gears to maxsimize FE..... but according to my experience ( i m no expert but this is what i have felt) riding the GS in ECO n PWR mode there is definetely a difference in pickup dunno about FE never checked so no comments on that.... but yes there is more to the modes than just blinking of lights... i m not assuming some advance stuff like the busa.... but yes its there for a reason..... if only someone could check the 0-60 time in both modes, both with accurate devices then we could come to know.... n yes the speed is limited to 110Km/hr in both modes... but hav reached 117 in god mode.....so definetly there is somthing which we r not enlighten about.... just my experience n 2 cents......

It is as simple as this: it is roughly calculated that 12-15% of the fuel in the half filled or almost empty tank is lost through evaporation and such amount of fuel is not needed to carry it. Remember that most of us are keeping the bike stationary for long periods.

If you need to reduce the weight, you can remove the kick starter lever, saree guard, crash guard and whatever you think fit to be removed and try to reduce a 5 kgs of your own weight.

The resonance frequency is not causing vibration in our bike. Mostly it is the loose/misaligned visor and rarely some other parts like engine mounting nuts. This vibration is widely discussed throughout this thread, forming a number of theories.

The reason for my beginning of participation in this discussion was this vibration and eco-pwr modes. It is difficult to explain how the vibration is dampened in our bike, but it is vibration-free at the top most speed, even at 200 kmh or more, if you can reach it.

After the finding out of the third law of motion by Newton who was a Satanist– and of course not previous to his finding out - there is an equal and opposite reaction for every action. Here it is the roaring engine sound we here after 80 or so kmh, a little loss of torque and different engine sounds we hear at different times.


My foes are increasing constantly; it seems! But I didn’t think about the effect of my opinion. But a truth is a truth and nothing but truth.

One thing I forgot to remind my beloved friend Augustine is Genesis 1: 1-6. The first was not light; it was darkness.

Have you heard about Aghoras? Spend a no moon night in a big grave yard, all alone. It will make you fearless by raising you to the ultimate stage of Nirvana.

@vishnu...i am not your foe..rather i am amazed about your knowledge of the GS if you really are from a village as u say...hats off to you..and i really mean that...

This facility or technology was introduced here in LML Piaggio 150 cc scooter, Supremo which I bought many years ago. Instead of the light, there was a continuous beeping sound when we reach the pre-adjusted speed limit of 40, 60 or 80 kmh, with a switch to cancel the sound.

The difference was that it gave us the option to adjust the speed limit manually.

Even though satellite.kid is using a 50-60 year old technology bike, he has the right to express his opinion here as it is an open discussion thread; I think.

Thanks for accepting me as a friend. Actually I am from a village.

Lights can be controlled by a switch even when engine is running (if the modes were only that).
Why the need to shut down engine for changing modes?

Im not challenging satellite.kid's right to freedom of expression. If he supports an arguement, Im asking on what basis he does that. No big deal.

what has conquering your fears on a new moon night in a graveyard got to do with aghoris?

Wow !!!!!

I left this thread a day ago in a friendly joking mood as if I was back to the dreamy teenage and I came back here to find the phrase "storm in a tea cup", ratified.

Well,everything here now humors me, even though there has been mention of Shakespearean language despite the fact that no users have posted the likes of "thou","thy" or "shalt" here.But that takes our conversations Off-Topic by a big shot, so I am restricting my observations here.

Now.returning to the GS150R:
@2TRama: having ridden the both Pulsar 220s, which they call 220F and 220Fi, for fairly long hours and in every kind of way possible,I can safely conclude that the erstwhile Pulsar 220Fi was the master of acceleration,yeah it was the faster of the two when i came to acceleration.The newer Pulsar 220F or the carbed version is the top end behemoth,which means it is the faster bike if we take the top end into consideration.But trust me,Pulsar 220Fi accelerated very fast and Pulsar 220F suffers in the 4th and 5th gear roll-on acceleration.From my riding experience,the Pulsar 220F needs a greater stick in the third gear to carry over the acceleration in the next two gears.Our bike GS150R does well in the roll-on accelerations.So keeping up with Pulsar 220F is possible till the ton mark in PWR mode.As far,my concern about Joel goes,he seems to be tired of my requests as I never avail his services(poor me,never gets the chance unlike few others in my city who went and got their bikes done),so may not entertain me frequently .

@all:Why does it always seem that the modes cause a difference in the performance of our bikes ???? I have experienced it a lot.I have personal experience of this:
On a certain trip when I was new to the GS150R, I used to ride in PWR mode,having noticed the change in engine beat.Now on a certain National Highway trip,I noticed that I was keep good company in a group of Karizma,Pulsar220 and R15.We were all accelerating and lowering and keeping riding like that,but due to presence of traffic it was not possible to push our bikes beyond 100 kmph.But on the return trip,the traffic eased up and the bigger bikes started showing their true presence,and suddenly I felt as if I was not being able to play catch up.So, at the next stop on the highway,I switched the mode off as I had previously noted that my bike did 125 kmph when in no mode but now it was only restricted to 111kmph max.So having turned the modes off,I too became a part of the high speed cruise where bikers were maintaining a constant 120 kmph speed.Well,I learnt something by myself and my bike earned itself the praises being only a basic common man's 150cc.
So I am sure about one thing,the modes does restrict redlining speeds on the GS150R..........and there is considerable logic in this.........if the modes were only indicators for newbie learners then isn't it doing the right job by restricting over revs or running engine in redline in order to minimize damage ???
On another context,the TVS Fiero F2 bike had this economy and power indicator and it had nothing to do with the rpms,some owners told me that if they just twisted the throttle the indicators of economy and power used to glow.So it was rather a switch only related to the throttle position, but had nothing to do with rpms.
The GS150R ECO/PWR mode in comparison is complicated......it needs 0 kmph and idling revs to switch modes,changes rev pattern and restricts redlining.
Maybe,the TPS employed on this bike has changed the simple system on the Fiero F2 to a complex one on the GS150R ,but one thing is for sure............the modes on this bike is more than just indicators.Even if they may not be as sophisticated as the ones on Hayabusa.The ones on Hayabusa remaps engine power delivery and exhibits different specifications of the bike in different modes.But the GS150R sports the same humble specifications in any mode but changes the way it is to be used.

I agree with you bro!
Even some of my friends made me believe that the modes had nothing to do with acceleration and power but my one super minded genius counter questioned them on same explaination given by you and they all ran out of words....few even had guts to say how can suzuki be so stupid to give the features of 16 lakh bike to a 64k(thats the price when i bought it)bike?



eww... that beep must be irritating....wasn't it?

Then i think my steed is some other breed of GS.....

@MACH50

Please write in paragraphs. I'm literally holding out two fingers reaching far ends of the lines to read through..

Great to hear GS earned praises though well deserved

I'll try to check out the mode differences as I'm going on a long haul (300 Kms on NH4) middle of next month (16 May).

i thought he wrote 8 paragraphs.....(though big ones...)
no offense though.....
NH4 is the simply best road to ride on GS....
