Re: Pulsar 200 NS Owners Review and Experiences

I think he refers to the CO. Because afr screw can all the way go beyond four turns. I think you should get through this thread, where he mentioned about the info that came from Bajaj itself



To know your current setting, turn all the way in... The thread says stock should be around 2.5 turns out from 0 and the CO should be 1.5-2.0 i guess.

Plus the afr fine tunes the pilot jet, not the main... One should depend on CO based tuning for proper results.

Re: Pulsar 200 NS Owners Review and Experiences

Sorry for the confusion. That is turns. Didn't go beyond 2.5 because you see, I mentioned 'beast' at 2.5. No point in opening the screw more and wasting petrol. These are settings for MY bike. Yours may or may not vary from mine. If your bike is sluggish in low revs, the best thing you can do is to turn the screw half turn anticlockwise (loosen) and see if there is any improvement. A difference of half turn makes a difference in mileage of 2-3, that's what I found. But that's in city/town in low/medium revs. On the highway, the difference will be LESS because you are mainly using the mixture from the main jet, if you ride above 4K rpm. Now, if performance in low revs improves, but is not satisfactory, loosen half turn more and see.

If you don't find any difference when you have loosened half or one turn, better return to the original position and troubleshoot other things.

Re: Pulsar 200 NS Owners Review and Experiences

Thats good info bro...

A thought just came up ..

There is a point mentioned in the above link, I quote "(2) the exhaust gas analyzer machine's nozzle should not be put into exhaust end outlet, because the catalytic converter reduces the harmful gas emission, so the PUC machine nozzle has to be inserted before cat-con, and company has provided a bolt specifically for this purpose in exhaust before cat-con, which can be opened with a 10 no. spanner. open the bolt and insert the nozzle of gas analyzer there, and then take readings."

Whenever I have taken my bike for CO tuning they just stick the analyzer nozzle into the exhaust pipe and then set it at around 1.5 - 1.6 ... Considering the fact that the cat-con reduces the amount of harmful emissions does it mean that CO readings are skewed; In which case any carb tuned this way to a setting of about 1.5 is running rich if we would measure it via the bolt provided for the same ? Any sense in what I am thinking ?

Some background based on this thought process - During my tour I got an overall average of 38 kmpl which were highway speed runs. Later on when I took the bike for tuning it turned out that it been running slightly lean. The svc guy had tuned it to 0.9 (based on PUC readings) which actually meant that it was actually more than about 0.9 since the CO would have been higher before the cat-con. Now that I got the bike tuned to 1.5 again through the exhaust pipe the mileage has dropped to 32 - 33 since I may be running rich .. Savvy ? Any thoughts ?

Re: Pulsar 200 NS Owners Review and Experiences

Did u try the 100ml test?

Re: Pulsar 200 NS Owners Review and Experiences

Yea bro got the aesthetics checked -

Chain slack - checked / cleaned and lubed
Clutch play - checked

ODO reading - 12,880 kms

Kms since carb tune - Approx 1000 kms (guess)
Kms since clutch plate change - 184 kms
Kms since chain sproket change - 184 kms (it was fine however had to get it changed due to uneven slack)
Kms since diaphragm change - 12,880 kms Never got that changed

OT - Is it diapharm or diaphragm ?

The only 100 ml test I know bro existed in Organic chemistry !! Mind enlightening me ?

Re: Pulsar 200 NS Owners Review and Experiences

Sorry diapharm. Well the problem lies in the diapharm.you need to change it as that's the reason why you see less pickup.just visit any SVC and ask them to change the diapharm and a spring which comes with it.costs some 300rs.

Re: Pulsar 200 NS Owners Review and Experiences

Haha.lol.
Well they have a can of 500ml I think where they disconnect the fuel pipe and then connect the can with the fuel pipe from carb.after that they pour 100 ml fuel and then ask youto drive.if it goes 3.7 kms that means your mileage is 3.7 x 10 =37kmpl.this is the most authentic way of checking your mileage.also you can find in any bike repair shop.they will only do the test ,its just that you ride the bike.

Re: Pulsar 200 NS Owners Review and Experiences

How freq does the diapharm need to be changed ?

Did I mention that the dull low revs happened post changing of the clutch plates and sprocket and since I was there standing on the head of the svc guy I know he did not fiddle with the AFR. Could it be linked to the Diapharm ?

I mean there was certainly an impact of the clutch plates and the chain which has defo improved however the bite is still missing. Guess no harm in trying the diapharm trick ..

Now the big question .. what does one say to the svc a-holes since they try and find every reason to avoid having to open the bike !

----consecutive posts auto-merged-----

Ahhh thats nice gotta try that one out ... Feeling enlightened already ... guess I do not need to go to Bodh Gaya now

Re: Pulsar 200 NS Owners Review and Experiences

Well yes they are Approved A-Holes by bajaj no doubt about it. I doubt it has anything to do with clutch as I think new clutch plate shouldn't have any problem.regarding diapharm just tell them u need the diapharm and spring changed.doesn't matter whatever they say just get it changed. It depends but i feel 13K kms is too long if you can feel the drip in pickup.others might say that its been 20000kms and still they didn't change it but its actually they couldn't feel the pickup being down yet.but before that go to SVC and keep the co level to 1.61 and then do a 100 ml test and see how many kms bike runs

Re: Pulsar 200 NS Owners Review and Experiences

The correct method to do a 100 ml test is, (1) first disconnect the fuel hose, then ride (or keep engine running in neutral) till petrol finishes and engine stops. Then (2) connect the 100 ml and ride till it finishes and engine stops. If you don't do the first step, you will have to watch the bottle and note the reading exactly when the connecting hose from the bottle goes empty (requires transparent hose). If you ride till it stops without doing the first step, you get mileage for 100 ml plus what was inside the carb (15-20 ml I guess, above the main jet level).

Re: Pulsar 200 NS Owners Review and Experiences

I was also facing similar kind of issues. But I had lot more like the acceleration wasn't constant and the engine used to gives hiccups and kind of resist from being revved. Mileage figure had dropped and the engine was harsh. So finally changed the service centre and have given my bike at another service centre they told me that they will keep the bike for 1-2 days and check it thoroughly. I hope this time the issue gets resolved.

Re: Pulsar 200 NS Owners Review and Experiences

Pretty analytical you are mate

Re: Pulsar 200 NS Owners Review and Experiences

Yeah its important to drain the fuel.also when they do the test ideally they will drain the fuel from the drain pipe.
