Re: Pulsar 200ns Power issues

Approved and merged!

Quite a few things:
1. Tyre pressure.
2. Chain slack/lubrication/cleanliness.
3. Bad carburetor setting (AFR).
4. Dirty carburetor/damaged or misaligned diaphragm.
5. Worn out clutch plates/sprockets (least likely at 10k km).
6. Choked air filter.
7. Bad spark plug(s).

Re: Pulsar 200ns Power issues

Hey Divya how to know if the bike is running on bad carburetor setting?

Re: Pulsar 200ns Power issues

Post pics of your spark plugs here. Preferably from all possible angles. The top portion that is!

Hi All


Recently fuel from my bike if i keep the Fuel Knob on "ON' or "RESERVE" fuel kind of dissapears.But if i keep it on "OFF" its fine.

Any idea why this is happening.ALso one of my friend told me that its normal in carb bikes.And no fuel stealing or anything.Its strictly that my bike if i keep the Fuel Knob on "ON' or "RESERVE" fuel kind of dissapears.But if i keep it on "OFF" its fine.

Re: Pulsar 200 NS Owners Review and Experiences

Ujjwal please see pics below. This was done up at my local guy in Gurgaon. Cost me 300 bucks all inclusive. Awaiting receipt of the brace cover and my phone mount so it may look incomplete.

Re: Pulsar 200 NS Owners Review and Experiences

Thanks bro for the pics it will be very helpful for me to source one and get it fixed.[emoji4]

Re: Pulsar 200 NS Owners Review and Experiences

Well must say nice jugaad.
But few questions
1. Any vibration or strange sound with the setup.
2.does it block visibility of console while driving?
And would love to see that brace cover on for sure [emoji5]

Re: Pulsar 200 NS Owners Review and Experiences

Thanks bro. As far as your questions go -

1. Nopes
2. Nopes unless you are obsessed with the flying B logo of bajaj .. LOL

On a serious note, the visibility blockage through this jugaad would also depend on your height too. I am all of 5 ft 9 and do not face any issues at all with this. Once the phone mount comes in it might cause a minor blockage in vision but it is something which I am not too bothered about since I do not use the console for anything, depending on instincts for downshifting, upshifting, throttle release etc, which I am sure we all do.

Re: Pulsar 200 NS Owners Review and Experiences

Anyone....

Re: Pulsar 200 NS Owners Review and Experiences

Do you park your bike under direct sunlight for long time? Due to this reason also petrol dries up.

Re: Pulsar 200 NS Owners Review and Experiences

No.I heard that if the carb has a stuck float it happens.But as i told its only when Fue is On!

Re: Pulsar 200 NS Owners Review and Experiences

Motorcycles traditionally have the fuel tank higher than the carburetor, hence fuel is fed due to gravity alone. What happens if you don't shut off the fuel knob/petcock?
Without the shutoff, if your carburetor float failed to close the valve tightly enough to stop the fuel flow, then fuel would continue to trickle into the carb, overflowing the bowl and flowing down into the intake tract. If the intake valve were open, it would fill the cylinder. Then, upon attempting to start the motor, the incompressible liquid gasoline would cause a catastrophic hydraulic lock.

Modern motorcycles have changed some of this in a few ways:

a. the fuel petcock could be vacuum operated, closing with the engine off. (as is the case in your bike)
b. the fuel tank could be lower than the carbs, making a fuel pump necessary.
c. fuel injection has eliminated the use of carburetors and floats to control fuel flow.

Now, the loss of fuel you feel is the slow trickling of fuel + evaporation.

Remember, the fuel shutoff has three positions - on,reserve and off. The difference between on and reserve is the length of the fuel delivery tube that brings fuel out of the tank. The "normal" 'on' tube rises about 'x' mm from the bottom of the tank. This means that when it stops delivering fuel approx 'x' mm of fuel left in the tank. The "reserve" setting fuel pickup is at the lowest level of the tank. It will flow fuel until the tank is empty.

In short, please get your carb float cleaned. It gets stuck as you correctly got to know.

Re: Pulsar 200 NS Owners Review and Experiences

Excellent Divya.Your points about any issues are always spot on.

yes tomorrow i will go to service centre.How i noticed it was that when i am doing reserve to reserver i was getting around 27,where it could have been 38-40.

Howveber once i tried to run the bike without stopping anywhere and viola i got 38.Thats when i got to know somewhere its leaking but no signs of any leakage .

Thats when i got to know it has to be a fuel + evaporation and a Etuck carb.

So is it serious and do i need to ask for a replacement of carb or these things can be easily fixed.

Re: Pulsar 200 NS Owners Review and Experiences

It's a normal issue, in fact it's so normal that SVC won't even call it an issue. It can be fixed. Just get the carb cleaned inside out. Ensure that the slide isn't sticking post cleaning.

Re: Pulsar 200 NS Owners Review and Experiences

Fuel float valve is either stuck or not properly seating , which is allowing slow drain into carb and then to atmosphere.
Petrol is volatile and hence it trickles down the overflow pipe and from there it evaporates. As of now rate seems quite low indicating the float valve is not properly seating

Potential Cause : Bad fuel / Aged rubber beak of valve
