Recently I'm facing an irritating (this is the first time this is happening on my NS) and somewhat dangerous issue on the NS.

I had some repairs done on the NS some time back and since the time I got the bike back, I'm having some issues -

1) There's a slight lag in throttle response (a fraction of a second, but it's noticeable). This happens specially when I crack open the throttle.

2) Cold starts have become terrible. 4-5 cranks or may be more. Last year during the winters this was certainly not the case.

3) The engine would just shut off abruptly during the first few km of cranking it for the first time after a long halt (say when I crank the engine for the first time in the Day or after office). There have been many occasions when the engine has shut off even after 3-4 km of travel. I would suppose that engine has got to it's optimum temp by this time, and should not shut off like this but it still does. A couple of times it has happened that I was taking a turn and the engine shut off (was quite an uncomfortable situation)

4) After ride, I'm generally smelling smoke from around the exhaust. I've revved the bike at idle and not much visible smoke is coming out till say 7k rpms. Post that I can see mild smoke (black smoke)

I'm guessing that this is an engine tuning issue, but any suggestions would be greatly appreciated. I would be taking the bike to service soon, but wanted an educated opinion before I take the bike for service.

Hello NSians.
I am upgrading from pulsar 150 2004 model 112000 kms done to PULSAR 200 NS tommorow. So I just wanted to know points that I have to keep in mind while getting delivery of my bike. I know that it has been posted many times before but I'm unable to find the points so please someone help me.
And I will be changing the rear tyre to Duke's rear tyre .
As it is a soft compound Tyre so will it have more punctures ?

My exhaust pipe is very brown permanently, looks odd when the bike is fully clean, all black but looking muddy on the pipe.
Any solutions? 7500kms on ODO.
I heard that idling a lot causes it to brown faster.

any solutions? didn't get any replies.

Get the tuning work done and i think your idle rpm is set very low that is the reason it shuts off when you twist the throttle all of a sudden.If this is not Idle RPM problem,i think it must be related to thermal sensors which detect the engine temp. and opens the coolant valve to flow into the cylinder (Dont know what this valve is called in technical terms )

Looks like a really bad tune or some carb issue. What is the current FE you are getting and how would you say the initial pull and high end pull is ? not talking about wide open throttle. but just some spirited revving.

Thanks Anurag for your reply.

The idle is at 1.5k rpms, which I guess is the standard for idling. Thanks for mentioning the thermal sensors, would get those checked.


Thanks Krishna for your response.

the FE I'm getting is between 35-40 kmpl. The bike does not have any issues with the pull and keep up the speeds. Early morning, first crank, it's a tiny bit sluggish, which is understandable. Once the engine is at it's optimum temperature, the bike pulls in the classic NS signature style. The only issue, it might still decide to shut off at a very uncomfortable situation.

I'm also guessing it's tuning and might be carb too.. so let's see what the service guys say. I'll definitely keep in mind the points posted here.

Thanks for your suggestions guys... much appreciated.

This is just out of my head. Put do check the condition of the spark plugs and plug cables. Check if there is some mis connections or shorts.

The mileage you specified seems to be the optimum , so it isn't too lean either i assume.

Damage assessment .
With a heavy stone upon my heart ,after 1 week of the incident that ruined my love ,I opened the cover for the first time to see what has been done ..
My deadliest issue ,
As you can see ,there is a big scratch on rright hand side of headlight .which is killing me the most ,so guys advise me ,i think that part is replaceable, should I go for tatto or tell me how to remove that scratch ( I cannot ride my bike with that scratch)
Also handle seems to be acting funny, as it seems ,the right hand silver colour bar is bent ,is it repairable. ..?
Will go svc tomorrow,
