Topic Approved.

Things point out towards the bike being lean. Find another screw on the carb with help of someone and turn it 0.5 turns towards "loose".

But don't just turn any screw, there's a drainage screw too which will leak fuel then and there... don't twist that one.

I tried it.
I turned the air fuel mixture fuel closed it fully and turned it to fuel side left one and half turns. I tried it till 2 and half turn but it didnt worked and as more towards fuel it would give less milege.

I think problem may be with auto choke ?? Its not working ?? No increasing in rmp while cold start

You are still running lean when at 2.5 turns open.The stock setting is beetween three and five turns.Try to keep it at four turns and then start the bike use it for some time and then keep turning it towards the leaner side(Clockwise) quarter turn at a time.Try to start the bike after each adjustment and settle at one before the last adjustment at which the bike does not start without throttle.My bike(RTR 180) and most of my friend's bikes(Pulsars & other carbed ones)mostly start in half a crank when well tuned.

I am currently running at 1.5 turns open.
I should keep 2.5 or 3 ?
Today i will try 2.5 open means still one turn to open.
But will it affect my fuel efficiency ?

Pulsar 220f carb tune up(air fuel mixture as well as idle screw)

Hello.
I own a pulsar 220 just 2 weeks old and i am getting many problems please help.
1.My 220 does not start in first crank during cold engine.
It happnes only once in a day rest is fine.

2.Currently i am running on 1.5 turns open on air fuel mixture screw.
First closed it fully and them opened 1.5 turns.

3.Will more turns reduce fuel efficiency ??

4.And idle speed when cold is 1k rpm and when engine hot it reaches 1500 rpm this much fluctuation ??

And a last thing
5.on slow speeds in first and second gear little jerks are exprienced.

P220 cold start problem.

Hi.
Plz help me i am tired of thos problem.


I own a p220 its just 4 weeks old.

Service centre response is worst

When i start the bike it just comes on and becomes off.
And about the autochoke i dont know it works or not i hv not seen rpm raising nytime ?
And i had my full carb. With autohoke replaced.
I have to accelerate for 10 to 15 sec. To keep it on.
Problem is only for cold or first start in a day rest it cms to life in half a crank.
Idle rpm in cold engine is 1k and hot is 1.5 k

Pls help me.
Thanking uu.
And a req. to administrator do not stop this thread.
Last time it was closed as a simple que.
I have not solved it yet so plz help me.

Topic Merged. This topic will NOT be closed until the problem is solved.

@ YashBM: Your earlier thread was closed because you said you wanted to know about AFR. AFR is simple stuff and the topic was solved by giving a link.



Tell me, did you try whatever was written in the above link?

P220 starting problem

Still the problem continues.
And ya samarth i have tried it.
Carb. Setting is fine.
And there are no much details about start problem cold in common problems.

Go and bang the service center guys.If this time of the year you are getting cold start problem then think about the rainy season and winter ahead.

Ya.
Here monsoon started.
Temp. Is 30'c to 36c

N autochoke engages only at low temp. At what temp. ?

There is no harm in giving slight throttle when starting up if it doesn't start without throttle. This is no FI that the ECU will take care of this at startup. For a Carb bike, you are the ECU, and you gotta do it yourself.

The only thing to avoid is to rev the bike over 6-7k within the first 2 minutes of startup, hence allowing the oil to circulate properly before you do that.

As for autochoke, on my bike, in the last 35 months and almost 39k km, it has worked on a total of 12 occasions. I really never felt anything was missing either.

Anyways, As I have already told you, Had you discussed it on the Pulsar 220 ownership thread and your problem would have been solved by now. But still, you didn't make even one post on that particular thread.

Finally, at ~4 weeks old, I think even the run-in and/or 1st service is not done yet. Please get 1st service over with *before* you touch the carb again. At 1st service make the SVC people solve the issue. If even then the problem is not solved, the difference between your cold and warm idle RPMs is too high and I feel that you are running too lean. Richen up the mixture just a wee bit and I guess that would solve your problem.

I have completed first service.
640 kms nw.
Oil changed.

And m new to biking so i dont know much
So i need help for that.
