Once while cleaning my bike I got an impulse to check out the air cleaner element. So I removed the right side body panel and inspected the air cleaner box. The air cleaner element was attached to the air inlet of the box and not directly to the carburetor air intake.
while searching the K&N site it was noticed that the air filter element was having a clamp like mechanism for tightening. But the stock air cleaner in GS was not having that. It was just kept in perfect apposition with the air inlet of the air box.
Air will pass through the air inlet, gets filtered from inside to outside of the air cleaner element and finally the filtered air is captured by the carburetor air intake(this is what I make up seeing the fitment in our GS).

I was wondering, it is given in brochure of unicorn that it is having viscous air filter. What can you comment on that..??

engine choking

@mach50. When I ride my bike at around 80-85 for like 15 minutes and reduce speed to around 55-60, i can feel the engine is choking. Can you tell me the solution to this issue? This happens regularly and in all modes. The engine doesnt stall but you could feel that the bike is choking. Raj

Guess some may know it already.. but this found recently. last sunday my bike's clutch cable went kapput. i rode the bike without clutch and reached mech shop (sunday so called my known mech to open the shop)

These days i thought clutch should be pressed for ES but its not all needed. guess there is a switch which presses when just lever is pressed and bike starts in ES.

Hi rajesh If u have remote lock , the bike will start without pressing clutch by pressing remote start....
How u manage to drive without clutch...I had very long back experience like this in yamaha RX100 ....it was late night in bangalore ...so no traffic no problem .. except a wheelie in first gear on first instance

when i started from thiruvanmiyur its hell lot of traffic so i decided to push the bike. then after some there was moving traffic . which is fine for me as i will get prob when standing.

after sitting on bike we need to move using our legs then put first gear and immediately accelerate thats it. then changed gears without cluth and downshifted in slow moving places then i brought to neutral when gonna stop in signal again step 1. it was diff exp. still i have the scooter clutch cable in my bike. though i have the spare GS cable i dint change it yet.

Mach bro i would really like to go with this mod. But i have a small doubt...what about the carb...??? will the Pulsar needle jet and RTR180 mainjet would be a direct fit onto our GS...??? If yes then will the carb work fine after modding ...as the amount of air intake will increase ???

Can you please give me the estimate amount required for this mod ???

The KN RC1060 is available here in pune for 1400 bucks....any comment..??

And yes i have found out a way to fix the KN filter into the airbox by cutting out the old filter and mounting the new KN onto the air intake pipe.

Can you elaborate what specifically happens during the engine choking..........
I need to know the feeling.

Our GSR is different from all bikes except the Karizma and the Wind,they too feel similar.
Due its dual throttle system along with TPS,when you decelerate it gives a mild jerk,also when you accelerate the feeling is same too.But its a nice feeling,you will find this on Superbikes too
Is this what you mean by choking??? or something else???


Please reply so that I can help

@Arish: Bro,the needle jet of P180 and main-jet of RTR180 would be a direct fit on the GS carb.........they all use Mikuni BS Carbs,so dont worry about that.I hope you get the KN mod right.What I would suggest is that,buy an extra air box and preserve your stock air filter and carb jets.Coz if any mod goes wrong,you can revert back to stock set-up.It would be great to see you doing the mods.
GS is my daily bike so it doesn't finds time to get the mods.
But Arish with the mods done you would have a really fast GS !!!!! Assured.

@Ksooraj:Viscous air-filter is made that it gets maximum oxygen to the engine cylinder for better FE and better performance.Generally Cold air contains maximum oxygen.I assume that this Air-filter extracts maximum oxygen to be introduced to the AF ratio which would increase combustion efficiency and would promise better power delivery and FE.KN does the same by introducing more air,as more air would have larger oxygen concentration.However performance wise KN is better.As because the stock output of the CB Unicorn remains same even after inducing viscous air filter.

I can feel as if the engine is not getting enough fuel from the carb. I can tell for sure that it is not a good feeling like you explained. It only happens after 20-30 minutes of high speed cruising. Again if i accelerate over 60 there is no issue. Raj

Your Carb is at Lean position.............and I am telling from experience,not by guess.

Tune it to 2.5 turns from lock position of the Fuel screw(360 degree turns I mean).Its the ideal specification of the carb,go by it.

Hi all is there any problems with gs150r like engine noise and other stuff. ? coz my friend is planning to buy a new bike .. can i suggest gs150r

the carb tuning is at 3 revolutions (360 degree) anti clockwise from lock position. It was at 2.5 from manufacturer. It happened earlier too. That time I thought the mixture is lean and therefore I tuned it to 3 turns. But the issue is still there. Anyway has it got anything to do carb jets. I mean is it possible there is some issue with the carb jets? Raj

Well Yes and no if your friend has ridden bikes earlier believe me he will go gaga over my bike which has done 7.5K kms and whose noise i think has increased a bit from last service.

But He will tell that it is the most silent bike he has seen. Well this is true if you drive other bike and switch to even the GS which people say is very noisy still it will beat other bikes on engine noise.

So after driving so many Kms i feel that i can't stand even slightest of noises from the engine now and it feels as if the bike noise has increased considerably.

So first thing no issues with the Engine it is rock solid. Only a little bit of niggling problems here and there but overall i will tell your friend to test ride a GS if possible which has done some KMs rather than the Test Ride bikes which usually have done 3-5 Kms atleast when i test rode them.


This will give him a nice idea about the whole Noise Confusion.


p.s I had complained to Suzuki about Noise so this time a Guy will drop in to the SVC and will ride my bike and See all the service and make sure that my Bike is perfectly all right.

So Suzuki Feedback page does work,You just need to push the right buttons.

Might be.......they need to be cleaned.
Carburettors does get dirty due to particles in Fuel ,get it checked at SVC.
Also dont forget to get your airfilter checked,airfilter clogging also may sometimes account for such.

From the manufacturer my bike was delivered with carb tuned at 1.5-360degree turns.

Bro, I too face the sam prob as basumataryraj. I've checked the airfilter in the SC, they said its fine even after 14K kms.(now completed 15K in the odo) The manual says to replace air filter @ 12K kms... but still they did not change. I faced this problem in the initial stage when I bought the bike but after sometime, it gradually left. Now its back .. My fuel screw it @ 3.5 turns. I feel there is some prob with the carb. My fuel effeciency has also dropped now a days(43 - 45 kmpl)... got to check. You have any idea ?

Even i faced the problem of bike goes like hitting reserver while creeping past high speed i faced it at 90 kmph while my carb settings are in factory default

now its going great as my fuel golden screw is 3.25 turns from full close.

our bike carb is very sensitive and typical one.

Guyz in reference to current situation stay at safer place don't ride as its not safer even if you have a helmet because all the helboys are gona start playing ayyodya game on the roads. so stay away.
