My mechanic had opened up another customer's GS150R's engine and I must say, like the Fiero even this engine has lots of potential for modification.
The exhaust port is covered too much, the port was opened up and my mechanic was doing some head job.
Got to ride the bike yesterday after all the works were complete... and I must say I'm damn impressed

.
The power has gone up very much, feel like its clean 2 bhp more.. Was able to do 126 on the speedo very easily, will check its full potential this weekend and update. The Acceleration was much better than stock, it was just like a P180 or an RTR

Aha! Now this is interesting.. Did the tuning affect the bike's handling? Was the engine still smooth? I always felt the GS is a bit underpowered, especially in city traffic.

It's too early to say for sure, but if this kind of performance can be achieved, ("clean 2 bhp more") i wouldn't mind tuning my GS too.. (After the warranty period, of course..

)

Wow!!!!!
Please do elaborate on this topic......
Even I too feel it is very much underpowered and the mileage it returns is the only factor which is driving me CRAZY

Suzuki GS 150R- New owner

Hello friends,

First, let me thank you all for the wonderful reviews that you have provided about this bike, to help me make conscious decision to own one.

. My salutations to ye all.

Second, the fotos/pics will be posted soon. It is the flaming orange colour and i have owned it for about a week now and done 130 kms on it.

lastly, I am Srinivas (aka Srini), age = 37 (bordering 38) from Pune, height = 183 cms and weight = 82kgs.

The reason for buying a bike is only one. Travel to office and back. 16-18 kms total. I have company transportation, however, my timings need to revolve around the same. So most of the times, even I am done with office work, I cannot go home because, i do not have a ride

. to get around this issue, I started looking for a bike. I have never ridden a 2 wheeler for the past 15 years. the last I rode a 2 wheeler, was my friend's, TVS SUZUKI Max 100R in 1995 just before graduating. I am a Bombay (Mumbai) ite and a ride was never an issue there. after graduation, I have always been on 4 wheelers. Therefore, taking a bike at this ripe age seemed a little, i do not know, not right, to put it lightly. However, with the company transportation issue, I decided to own one. after much deliberation, zeroed in on 3:

Honda Unicorn
Yamaha Gladiator
and Suzuki GS 150R. The only reason being, the advert and some reviews on zigwheels.com

I had almost decided on the Gladiator, because of

price
mileage.

However, after reading the review on Zigwheels and found out about this ownership thread, I decided to take a test ride. I took 3 friends with me, each of different age groups and sizes to help me understand if the bike is good.

First test ride with a young colleague/friend of mine:- age 28. He was impressed with the stability and the pulling capacity on low speeds and high gears etc. this guy though is shorter than me 5ft 9 and likes the FZ too much.
Second test ride:- age 33 colleague/friend, but huge. This guy drives a CBZ extreme. He was massively impressed with the ride quality and the suspension.
Third test ride :- same age as 2 and same build as me. He loved the ride quality and smoothness of the gear box.

So armed with these facts, I booked one on Wednesday, 10th March 2010 and got the delivery the same day. I took one extra day for delivery as I wanted the RTO number on it rather than go back to the dealer to stick the same.

I have travelled 130 kms on it since and love the way it handles and more importantly lets me handle it. Suspension is amazing, gear shift is beyond compare. The dashboard (if one can call it) is unbelievable. In fact, the gear indicator is one of the niftiest features, else, with the butter-smooth gear box, I would find it hard to figure out what gear I am in.

.

The vibes at 3500-4000 rpm that some people spoke about are there and these are not vibes per se. Its just that the bike sounds different at this range. and I firmly agree with mr. SivaKumar, who mentioned, that it is the bikes sweet spot. I am almost on this 3500-4000 rpm range and feel, that the bike is asking me to take it beyond the 4000 rpm range ASAP. However, I feel it is at this range, that the bike's mechanics will start meshing well with each other to give us a longer life.

I have not tested the mileage yet. however, I should mention that when I got the bike, I filled 5 liters of petrol and at about 90 kms, I had to move to reserve. As the bike has about 3.5 liters (is this figure right?) reserve, I assume i got about 60 kms. I think i have got 55+ and < 60 though.

more soon.

PS: another thing to note. There have been some queries on running in a new bike. One of my friends sent me this article. though it is defined for an enfield, i feel the same should/would apply for all new bikes any make and size.

@Srinivas: Welcome to the forum buddy and congrats on your new bike.

Regarding the break-in period, go through the owner's manual, it has the information regarding the RPM limit for certain KMS, and all other needed stuff.

I think its a max of 5000RPM till 800 kms and 7500RPM till 1600 Kms.
Don't ride in constant speed for longer period.
Use the kick lever to start in the morning and let it idle for atleast 30 seconds.

The bike is really great and a very nice commuter.

@Joey,

thanks buddy.

Right I have been trying to follow what the manual book says regarding the run-in specifications. On top of the same I have also trying to follow what the website i mentioned says.

.

Hope to have a long-lasting relationship with the bike.

@road_ripper:
Bro could you please elaborate on the changes made to the engine. I'm not that technically sound but curious to know how the power is increased by opening up the exhaust port. Is it mere enlarging the exhaust port ? or something else ?

I presume the number of cycles would increase by doing so, there by increasing the rpm. Do you mean to say that the torque change could possibly increase the power ? Kindly bear with me if I'm not talking anything sensible here.

I guess you know how a four stroke engine work. Out of the four strokes( Intake, compression, combustion and exhaust) only combustion is the power stroke all the rest strokes are idle and uses the momentum created by the power stroke. As our motorcycle engine have only one cylinder, even a small reduction in back pressure can make a difference. If you are opening the exhaust port it means that you are reducing the pressure required to push out the exhaust gases and more heat is transferred out of engine.
To make this point clear, imagine if you are waving your hand in flame very fast you can hardly feel the temperature as it take a particular amount of time to transfer heat. So if the exposure time is less that means less amount of heat is transferred from the hot gases to engine.
Please correct me if im wrong.....

hey the japs are visiting hyderabad from 22nd to 24th. i got invitation today

**csp007chinmay** · 03-19-2010, 09:56 PM

hi friends!
done 1st service last week.
but after riding haven't felt much difference.
instead gears are making much noise. & feeling somewhat under powered.

engine makes lot noise at lower gears. though i keep rpm below 4.5k

also idle speed is around 1.3k when i start my bike in morning & then it shows around 2k whenever i start bike later throughout the day.

this was not the case before.... but the bike is awesome & i love my bike

pls comment.

just for curiosity, can we replace handle bar of GS with clip on handle bar?
wiil it look good?

I'm not a mech student, just studied mech in 1st year of engineering so know lil basics..
the explanation seems correct..

But what bad effect would making a larger exhaust port have ??
(just to figure out why suzuki didnt do it in the initial design itself).

which engine oil is better fo our gs150r

Check if the chain is too tight. It happened with me once. after service I felt that the bike lost all its power and even more noise. then i took it back to the SC guys. they checked it loosened the chan and the bike was good.

though i keep rpm below 4.5k

also idle speed is around 1.3k when i start my bike in morning & then it shows around 2k whenever i start bike later throughout the day.

this was not the case before....

Adjusting the idle screw is the easiest thing to do(refer your manual page no. 6-24). when the bike is warm enough or after 5 kms of riding set the Idle to 1.5K RPM. that will get things into prespective.

Enjoy the 'smoothest Indian'!

I've my eyes set on the Motul 300V 4T 15W50 100% Synthetic Engine Oil. The only thing stopping me is the price... Rs. 895

for 1L. I think this oil will counter the roughness after the engine is hot.
