@ Sylvester

You said a point. The other person who mentioned tightened chain issue was Basumatyaraj and from his post it was very difficult to ride and had hard gear shifts and all. I thought you would have realized the problem with a Km or so and could have rushed to S.C. I remember how the technicians tighten the chain. They use long spanners and how did you even adjust that. After cleaning with tooth brush spray some more kerosene and wipe with a rag. Even if the rollers are free rolling there will be granules of sand which will make a noise. During the rainy season the sides of the chain will rust quickly and lube the side walls. If possible open the primary sprocket cover. There will be high sedimentation of oil and dirt which will be making contact with chain all time. Remove them as well.

While applying lube apply very thin uniform layer and do cover the side. Even if you apply excess oil it will be washed away when we ride in high speeds. This excess oil will remain in the chain cover and will catch dust particles.

Here is a way to drag the GSR.
1.If you are new to dragging,you should know the basics first......
Never watch for the speeds at which you are shifting,watch the RPMs.
2.Loosen your clutch play on your GSR,so that you can feel butter smooth shifts,sometimes it so happens that hard shifting gear lever messes the quickness of drag reflex.
3.Dont swerve your bike while dragging,make it go as straight as possible........GSR,is a beautiful bike,it corrects all tendency to swerve while sudden acceleration.

Ok, i'll first get the clutch checked..
I saw the manual for clutch adjustment,
After loosening the 2 bolts on the engine, should i turn the screw clockwise or counter clockwise to loosen it ?
(my bike is tuned only by the SC so i guess it has a tight clutch setting)

And can we use clutchless upshifts on a regular basis and while dragging to reduce shifting time ?
Some of my friends never use clutch for up shifts on their pulsars and the gears seem pretty ok (doesnt look like its messed up or anything)

And lastly, have u checked what mileage you get with all this dragging ??
(if i use shell petrol, even with rash riding i get around 50-52 (55 with sane riding),
But with other petrol if i ride rash a get only 45 (48 with sane riding)

After you loosen both the nuts, in fact loosening only the right nut will do. Turn the whole assembly counter clockwise direction to increase the play

.

Clutchless shifting offers rapid power delivery and it does no harm if done at proper rpm. Find a sweet spot to shift gears. But you will have to use clutch for downshifts otherwise it may make a thud noise and may suddenly lock the rear wheel.

@ MACH50

How did you calculate the shift patterns? I guess you stated the shift rpm from your experience. Is there really any torque shifting and power shifting techniques? As far as I know there is only one ideal gear shift.The optimum shift RPM will probably be different for each gear. We can calculate the optimum shift points, but it takes two pieces of information : Gear ratios of all our gears, and a chart of our torque curve. The torque curve usually have an exponential growth and fall after a peak rpm. An ideal shift always occur after maximum torque rpm.Whenever we shift to next gear the rpm reduces. The optimum shift will be at an RPM where the engine will make more torque after we shift than in our current gear.

I didn't mean what you stated is wrong, I just stated this to make clear why you specified some rpm for maximum performance. If only I could get hold of torque curve of our GS, can calculate exact shift points.

@AnupDas.......a lot depends on experience

I had my calculations........yes there are really two patterns.

@Falcon.......dont mind mileage,for GSR it never goes below 45kmpl.And you wont be dragging always

**Anupdas** · 07-01-2010, 02:34 AM

I wonder if our S.C have torque curve of GS

. My next service is dated on 13th July. If anyone is going to service centre before me please ask if its available to them

. We can just calculate ideal gears shifts both for power and fuel economy

false reserve

feed her with 2 tr petrol and gone for 60 kms long ride (bangalore to bannerugatta)
Then used for local drive all these happended with pillon rider got reserve was wondered as it goes only 94 kms (42 kmpl)
I got suspecious so after 2. Kms turned back to main it reached 21 kms and reached reserve so the caculation is 21+ 94 = 115 / 2 ltr
The mileage is 56 kmpl

Not bad at all with a 62 kg pillon

Going for 3rd service tomorow

**MSN1** · 07-01-2010, 12:06 PM

correction its 57.5 KMPL

Yeah 115 / 2 = 57.5 kmpl

But i must admit one thing..
I get smoked almost everytime if i'm dragging with any 150cc bike when the signal becomes green.. even the old unicorn

I'm not blaming the bike though.. since this is my first bike i'm not used to shifting gears with a racing orientation.
I guess i take too much time to pull the clutch, shift, and then release clutch and accelerate..

I am also with you Bro. Same is the case with me. Even i almost always get Overtaken by other 150's. Feels very bad though.

I thought that probably my Bike is not tuned properly for good Pickup or maybe I am not a Racer Type of Guy.

Today I dragged my bike with my friend and Xbhp member Nighthawk_Lee on his R15

No one got smoked,though I had my nose slightly ahead !!!! We both reached 100kmph equally fast and then ran out road

I know I would have had lost after that............R15 reaches 130kmph with ease

Now this is really a big compliment for an air-cooled 2 valves 150cc,though the bike was in no power mode again,and that too sitting straight,while any R15(Liquid cooled, 4Valves-LC4V) begs you to crouch in comparison

(Nighthawk_lee is one of the most bad ass riders.....he uses R15 to chase away the likes of Comet and Ninja in our locality,so no doubt about the rider)

GS150R.......the magic lies in intense high rev gear shifts with the clutch fully pulled in.
As for the thud sounds at 25-26kmph shift to second gear---NO, my gearshifts are smoother than any Unicorn I had ridden so far,namely my friend's own 2nd Gen Unicorn and Xbhpian Wingryder's Unicorn too.What more I used to smoke Unicorns with my modded Zeus

GSR is way above.......

Here is a way to drag the GSR.
1.If you are new to dragging,you should know the basics first......
Never watch for the speeds at which you are shifting,watch the RPMs.
2.Loosen your clutch play on your GSR,so that you can feel butter smooth shifts,sometimes it so happens that hard shifting gear lever messes the quickness of drag reflex.
3.Dont swerve your bike while dragging,make it go as straight as possible........GSR,is a beautiful bike,it corrects all tendency to swerve while sudden acceleration.

Now the secret,
Based on calculations there are two types of shifts used in a drag,
Torque shifting and Power shifting.......a third type of shift is customised and is mostly for the pros(this is the type I use)

Torque shifting-This involves playing with the torque curve,the max torque of our GSR comes out around 6500rpms,you need to shift quickly when this rpm is reached,your bike will surge forward,as in every gear it gets to build up the peak torque.
So....thing is always rev at 6500rpm-1st gear(quickly shift the gear),6400rpm-2nd gear(quick shift),6300rpm-3rd gear(slow shift),6200rpm-4th gear(slower shift),6100rpm-5th gear(still slower shift),6000rpm-6th gear(slowest shift).The short gear ratio of our GSR really compliments acceleration,cupled with its meaty torque curve......a bike like ours would emerge like a diesel train headed towards the Capital

The RPMs climb faster in power mode.This method is more useful for streetfights and in city overtakes of a fast moving vehicle.

Power shifting-People who are too conservative about riding their bikes,wont follow this process

This involves shifting near the redline or the peak power curve.
Same as above.........only that you have to Shift the 1st gear at 8500rpm......then reduce rpm shifts as above,the bike usually flies in this mode and it really requires very clear drag strips otherwise it maybe dangerous and maybe slow due to sudden braking to avoid obstacles.This is a professional method.Engine is hard revved and stressed.Same thing for the power mode too......and it helps you to shift at power curves.

My own customised shift...
1st gear at 8200rpm
2nd gear at 7600rpm
3rd gear at 7000rpm
4th gear at 6800rpm
5th gear at 6500rpm
6th gear at 7500rpm

By this method..........my bike gets the advantage of the building Power at high rpms and when a shift occurs,it falls directly on the Torque curve.Nowhere the bike is left without momentum and it accelerates its way away to the sky

This is enjoyed more on ,my tuned 2T.......as it reaches around 130kmph with ease.
Tried this on my GSR and it smoked all 150cc and ran along with R15,ZMA and P220

Very Good Write-up Bro. Even i am in the same boat as Falcon. Even i get overtaken by Pulsars and Unicorns and FZ's. Forget about the R15's and Karizma's. Guess i do not have the Racing Instinct in me. But deep down, i always want to smoke the Pulsars and Unicorns and all the 150 CC's.

Do you just Rip the Throttle everytime in all Gears ? I think my Problem is that i take it a bit easy and almost always i change Gears at around 4 - 5 RPM.

You seem to be a Lot into Bike Mods n all. I am planning to fit a K&N 1060 on my GSR soon and do Upjetting. I want more Low end Torque and initial Pickup.
What are your thoughts on this ?

GS can easily smoke any other 150cc's. Hard revving is the only way we can do so. Do you think other guys are taking it easy, they are giving their bikes a tough time to beat us as well? Our forum dont promote road racing, but I guess once in a while its OK to have some fun. So far I had drags with Hunk, FZ and RTR 160. Only RTR was a tough one and I was able to cover him by out braking ( The guys panicked on hard braking). So it all depends on driver skill, our bike is the best and identify where she does well.

You are the first one to mention about fitting high flow filters, if you can find a good mechanic it will be fine. And do post about the performance.

I'm not here for brand wars please!

Tried smoking the R15?

You're right when you say you have to rev the bike high though! & yes, rider skill is also important, infact the bike is also equally important.

Oh god did I say R15

! Its always an exception when we say about 150's

. Infact I always think twice to overtake even a slow going R15

, what if he gets offended and smokes me right away? My pride will be shattered

well bro do u have idea abt which one(reserve knob or float or tank design) cause this false reserve???
I feel look wise GS150R R to R knob good but built quality(only R to R knob) ????
I have to post picture again from where our R to R knob from?

Hehe.. Its afterall a 150cc na, so its included in your general statement

You can overtake a slowing R15, even if he smokes you out, the score remains 1-1

Anyways, the GS150R is also a wonerful bike man. Superb styling I would say. Congrats to all you guys owning one.

I'm yet to ride one though

I doubt anyone in xBhp B'lore owns it, and even if they do, they never come for any g2g

Ha ha, who will be satisfied by doing so

. Atleast you ought to get a superb bike giving 1lakh

Thanks bro for your good words. Infact the Japanese bikes are all real pieces of engineering. To my knowledge two of B'Lore xBhpians own GS[ Falcon and MSN1]

Did you consult with the service centre if we can fit RC1060 ?
I thought it may not be possible because our air filter seems to be enclosed in some cylindrical place..

Even i thought about fitting it, but without upjetting and if it does not decrease mileage. (just for the sound)

There are quite a few b'lore xbhp members with GS.. dont think most of them are active here though..

And about the g2g's, i didn't know there were any in b'lore firstly..
And the tri state one which is advertised above, my sem exams are going on and i doubt my parent would have let me travel so far anyways.
