Re: Unidentifiable problem with Pulsar 150

Approved!

Things to check:
1. Carb slide.
2. Diaphragm.

Re: Unidentifiable problem with Pulsar 150

My mechanic told that diaphragm MAY be faulty(cannot be checked w/o replacement) but only diaphragm is not available as a spare part and whole carb has to be replaced. Only diaphragm is available as a local-made parts but these are not successful

Re: Unidentifiable problem with Pulsar 150

I think diaphragm is available as a spare part. Did you ask in the asc?

Diaphragm is available as a standalone spare.

Sent from my phone. Kindly avoid it while riding.

He is fooling you. Diaphragm is a separate part. I had got it replaced for my 200 NS

Re: Unidentifiable problem with Pulsar 150

Wondering if it's a case of faulty parts then how come it started running smoothly after cleaning. Maybe issue with the petrol tank (rust/dirt)?

Re: Unidentifiable problem with Pulsar 150

Yes, even ASC said that loose parts of carb are not available. The whole carb needs to be changed. Now I think I should try some other ASC also

No, it's due to the weak diaphragm rubber, when he cleans it will work for a few kilometres but it'll be back where it was later.

Hmm, as far as I know it should be available as a spare part, no one replaces the entire carburetor for a diaphragm. Check out in other asc. Also ask in some local spare shops.

Re: Unidentifiable problem with Pulsar 150

If the Bike runs properly after carburetor cleaning, there are only two possibilities...One is Sediment in Carb float bowl, Jets getting clogged..For both reasons suspect the Petrol Bunk for Adulterated fuel, or Debris, or Rust in Petrol Tank.....A bad Slide /slide skirt will not allow the bike to accelerate and RPM will remain below 3~5 K...A sudden stoppage is due to Petrol Flow getting stopped... Have you checked the inside of the Petrol Tank for Debris, or Rusting ? Get the Petrol Tank cleaned and see if it solves the problem

Hi guys,

I'm encountering this problem with my 2003 pulsar 150, was hoping you guys could throw some light on the issue.

When the Engine is running idle, it seems to miss/stop for almost a second and then jumps. Even when the bike is running it behaves in the same fashion. Sometimes the bike stops in the middle and then its is impossible to start it,

I encountered this problem for the first time around 2-3 months ago. I showed the bike to the mechanic at that time who after checking spark plug etc said the carburettor needed cleaning. He cleaned it and the bike started working fine. Now after running for about 500-600 Kms the bike again started giving the same problem. I ignored it for the day(as the bike was at least running) but it suddenly stopped completely. Just before stopping it gave a sort of click-click sound (from the area around the engine). Showed the bike to the same mechanic and he said the problem was again with the carburettor. He again cleaned it. The bike is running now but I am no longe confident of it. The mechanic is saying that the carburettor may be faulty and should be replaced. He said that carburettor cannot be repaired. I showed the bike at the authorised service stn. They were not able to reproduce the problem so said I should 'TRY' changing the crburettor. They also said that carburettor is not repairable.
New carburettor for Pulsar 150 is for abt Rs 2000/- and I'll get it replaced if the mechanic/Service stn guys were confident that replacing it would solve the problem but none of them is committing anything.

Please tell me what the problem could be, and the solution for this.

Thanks a lot
Ankit

If every thing worked fine in the Carb, then I am sure its the float. Its a plastic device which when becomes older, it looses ability to block the fuel by valve.compressor.
It shrinks when dipped in fuel for a long time. Have you noticed any overflow? Check whether overflow pipe is blocked.
Just try replacing the CDI in ASC and check. I told this, just to confirm the problem.

Re: Unidentifiable problem with Pulsar 150

do all the things mentioned above,
psr mentioned a good point about getting the quality of fuel check and getting you tank inspected.

cdi as Jackson mentioned should not be ruled out, it would be worth checking that aswell.

but do stick to the original parts if replacement is needed.

and please do get the valve clearance adjusted at service center its often neglected,

as for the carb issues, you are in merut, hmm. if you happen to be around ghaziabad any time soon, let me know
i have a spare 150 carb used barely for 10 - 15 kms. so almost brand new and you can have it.

Re: Unidentifiable problem with Pulsar 150

hi buddy i got this problem in my bike also honda cbr 150r,
its simple it can happen in any bike , if my problem is same as yours of course.

the key holder[where we lock/unlock/start] in our bike, if the wiring connection is loose, this problem could happen.
if suppose you simply play around with the key in aniclock wise or clock wise for 1 degree the bike will stop and turn on again.
this is just a wiring problem i believe. becuase i have this problem in my bike, i have to replace it.

sorry if yours is not my case
