hi frds few days before i hit bike on back side of one tempo.. but i didnt fall down& my mudguard has broken. but after that i felt some difference in handling of my bike.. i report this to the service centre when i went to change the mudguard. but that personnel drove my bike and told no problem with wheel & fork.. but i still felt the same. it is like..

i am feeling some sort of looseness in the handle (but actually it is not)which means i have to give some extra effort to control the handle

when i drive my bike over small stones i feel some sort of rolling or lateral movement.. i know it will be like that only over stones.. but its something diff.. and it gives some thud.. thud.. sound (i guess it comes from that handle bar fixture & headlight area) even for a small potholes..

and once i crossed 60kmph to 70kmph.. my bike becomes very unstable. i am really afraid to drive my bike in that speed.

so i made all these complaints to the SC again and he told there may be some disturbance in the cone ( i dont know actually where it is) will change it if it is necessary.. but during delivery he told there is no problem in my bike.. & billed fork overhauling - Rs 170 & fork oil - Rs 96. but even after that i am feeling the same..

so guys please some one tell me technically what would be the problem in my bike..

thanks.. and sorry for this much long post..( i really want to rectify it as i have to travel about 60 kms per day)

The layer was not formed in oil or petrol but in the cylinder. A thin film of oil is scraped along the cylinder wall during the upward motion of the piston. In the combustion phase some oil will remain along the cylinder and would burn. This process may leave some kind of layer if there are any unburnt additives in fuel or oil . Seemed possible to me

I heard this information from Madhu. A friend of his owning an FZ used synthetic oil when his bike was still in break-in period along with shell petrol. He had an engine seize and had to replace the piston and rings. The mechanic who opened the engine peeled a layer of thin plastic like layer from the cylinder.

The layer formed was believed to be from the additives in petrol and synthetic oil aggravated the condition. It seemed logical to me, those who know about this matter please comment.

This matter was discussed to eternity in our thread itself. Many have felt a difference in both modes and got different mileage in both modes. If its just as simple rpm indicator why cant we change the modes when the engine is running? And why is there some wires coming from the carburetor. These are not mine, just a summary of I have read before.

Eco mode: GS has Xtra low end torque(bike moves in first gear just by releasing clutch gently ) and engine wont revv easily. feels like mini bullet
Power mode: not torquey as eco mode, one has to rev a bit to move it from stand still. engine will rev happily (will reach 80-90kmph in no matter of time)

Bold ones are my experience

when TPS is disconnected from CDI, engine cant get the signal from accelerator. results in poor throttle response. THERE WILL BE NO DIFFERENCE IN THREE MODES

So there is a difference between the modes, if everything is the way it is set(without disconnecting the TPS).

Do you know anything about synthetics forming a layer on cylinder?

thanks siva for such good info I never tried that experience by u,thats why i don't feel any diff.........that mean the black thing attached with carburetor is TPS one??? is it???
Do u have any idea if DTSI(twin spark plug) in pulsar implemented in our GS150 , How our bike behaves...????..I mean if suzuki do it not our own modification

can you elaborate on use of too much clutch!!!!
(i use it for changing gears and while slowing down from high speeds)
so is it recommended that one should not hold the clutch while slowing down and only use it for gear change???(i have just 8.4k experience while driving a bike,i use to ride a kinetic honda earlier)

i ENVY you!!!
oyeee......15W50 is for pulsars and that too bada wala..........not for us.....you should have told hemant bhai to give you a 5w40 or a 10w40 one.....thats available with him!!!


@anup.....synthetic oils are generally sludge free.....and madhu's friends FZ was still in run in period in which it is not recommended to use the synth as in run in we need friction which helps settling of engine....and synth provides low amount of friction......


@all
went to NH3 today for my second winter ride.....a small step towardds the biggie SS1k ;-) in jan/feb..........it was a 300kms return trip which was done in 3.5 hrs with a stop over CCD enroute and fotu sessions!!!!recently changed to castrol power 1 semisynth....it is not best or not bad.....it is good types....i feel motul 3000 4tplus mineral was good......so you can assume the quality of ride.....i got a stretch where in i was driving at 125kmph+for almost 3kms!!!!
i felt insane!!!because before whenever i drove i used to touch 127 mark for a blink of second and then speedo shows 120-123....but today it was showing 125-6-7-128 not for blink of second but for the whole distance......
i thank my GS for giving me a experience of ultra high speed on a 150cc COMMUTER!!!!!

@anupdas: It seems that the jelly like layer formation is associated with engine glazing caused by use of synthetic oil during run in period along with bad run in practices. Its is by no means associated with shell petrol or any petrol, from what Ive read. There are many websites that give some information on this if you google engine glazing or bore glazing.

Perception varies from person to person
The next thought in my mind is to rob an oil tanker from the highways.
How can people get away with the fact that Fuel prices has increased again.......this time by three rupees !!!!

A Superbike does 200kms on a full tank,under Indian conditions..........
can there be something called affordable performance ever ????,
Hard to remain loyal on this side of law.

@ Ram

I tried to point that such a layer may form by using synthetics. Who would buy a dog that bites its own master ?

@ Maestro

Minimal use of clutch means, using clutch only to shift gears. On braking some dont release clutch keep on pressing the clutch and try to shift all sudden. By using a sequential shift one a time and releasing clutch the engine braking can be used to slow down. While braking if we suddenly pull clutch, the load is taken from the transmission which speeds the bike.

Also dont pull and release clutch while taking a turn to avoid a gear shift. Earlier I was not mentioning about Sludge but a a plastic like layer formation.

i got it now.........will try this.......also i have a query.......suppose i am going down a slope on a flyover....there are two cases
case 1:with the clutch engaged completely from top of the slope to down..
case 2:w/o engaging clutch and closing the throttle with the higher gear..

so in what case will the fuel consumption be more??

I cant say for sure which gives better mileage . But while riding downhill always select a gear which will keep the engine rpm within 4k rpm, this will provide engine braking and hence we dont have to use brakes. I always do this to cool the engine after a steep climb.

After all it will very tiring to keep pulling the clutch all that time.

i'll make it simple.....
does using clutch except while shifting increases fuel consumption???

i had a small ride as mentioned up somewhere!!!
Thought mast fog shog milega........but kuch bhi nahi mila.....upar se gaadi slip kiya........that sumo bugger entered the one way in opposite direction.....was cornering ekdum se saamne aaya to gaadi to raste ke niche le jaana pada.....brake maara aur gaadi wahi pe skid kiya....main gaadi ka engine band karke jump maara....aur right shoulder pe land kiya!!!!!!riding gears the isiliye bach gaya........road ke ek side pe uncle log chal rahe the......unhe laga bahut kuch laga hoga.......but not even a single scratch.......to me or my bike.....baaki to mast tha..........average speed nikala to it was 97kmph.....302kms in 3.5 hours with a stopover at CCD and some fotu sessions.......also did manage to do a 128kmph on speedo for a nice 2-3kms.....
then went to andheri.......and man o man..kya traffic........idhar udhar se kaise to nikala......then thoda TP kiya.....phir college gaya.....aur sion link road aane ke pehle socha ki thoda kuch kha lu.......to sandwich wale ke pass ja raha tha aur signal red ho gaya.........saamne wale trucker ne brake maara,maine bhi maara.....wheel lock hua aur main thok diya......head lamp .75cms se displace ho gaya.....
ab bas.......itna kaafi hua aaj ke liye soch ke return aate time 60 cross hi nahi kiya.....

Had been to Yamaha Showrrom recently. They had a board which displayed a list of do's and dont's in which one states as " Avoid using clutch except while changing gears for better fuel efficiency"

Since then , i follow it..

I thought my earlier post cleared your doubt. Each time you pull clutch some of the power is wasted by free wheeling, so the more you use clutch the more power is lost. But this loss is not that significant, but by minimizing clutch usage its operational life increases. Thus its a good practice to reduce the usage of clutch to shift.

So you had a rough day today, even with protection its not all feasible to ride at high speeds that too with low visibility in fog. Drive safely and responsibly.

ohhhhhhhh its that way.........
thanks........
@prateek how is the 220 steed guy here.......and do go to the bhandardara ride......you may clock unbelievable top speeds......
