One help needed

I have noticed one thing in my bike please help and guide.

When riding the vehicle at top gear 5th at 4000 rpm the bike used to be touching at 60 now its 56. Is it because of the co what the guy did I am attaching here the co% picture which the mechanic has set at my bike because of which he had fiddled. Should I ask him to bring it back to 1.5 to 2 which the company recommends. Or just leave it. Actually when going above 4000 rpm the bike feels to struggle a lot??? Please guide what to do these mechanic oh god when will they learn.
Plus the rpm which has been set right now. Please help and guide what to do know....
Thanx

No stock P180 touches 60 at 4k RPM.

55 kph is the accurate speed @ 4k in 5th gear.

CO has nothing to do with that. Engine RPM is directly proportional to the speed of your bike when clutch isn't depressed.
Only and only dead clutch plates, flat front tyre, flat rear tyre and non-standard sprockets can change that proportion.

Set AFR screw to 2.5 full turns (ie 360 degrees) from fully close position. Do it yourself. That's factory setting for P180.

Re: One help needed

I think the co reading is on the higher side.. should be around 3.5 ish max -- pls correct me if someone had the right info on this

for the afr screw it has been done I guess. The reason why is because today I checked it while running the bike at 4000 rpm it was exactly at 55 - 56 km/hrs. Well but I am dam confused reason being when the bike was fresh and brand new I had checked it the bike used to touch 60 @ 4000.
I shall take a test ride of a brand new Pulsar 180 ug4 soon and take the snap or a video of it so that I can prove it.

The main head manager has set my afr in presence of the engineer from the company because an email had been sent to them. I believe Bajaj will do there work only after they received an email from there main heads.

nope as per the company the co should be 1.5 to 2.5% not more than this. This is the correct figure of the co for Pulsar 180 and 220cc confirmed it from the engineer as well here at Bajaj they have written on the wall where they set the co for all bikes.

petrol

I noticed one thing which I would like to share here. When I had delivery of my bike I got a full tank with bp petrol then when it got over I mean reserve I switched to indian oil. Now the scene is that I can feel a lag in low rpms as if a miss of petrol to reach. Maybe I am wrong but I confirm this when I get bharat petrol filled again then I shall come to know the exact thing. with you all which petrol easily suits our bikes. In my previous machines I used to use speed normally but now in my town because of 0 sale of the high octain petrol no dealer is getting it. Hence only normal is available that's why I am asking this question here.
Thanx

that is what i said

the reading in you pic was showing more than 4 and i said it was on the higher side.. and 3.5 should be the upper limit.

yes the reading in the picture was on a higher side that's why they changed the co setting to 2.5% and not 3.5

In pulsars the tachometer is lazy compared to the rate at which engine changes its RPM. Tachometer can't keep up with engine. During the high acceleration scene it's very much possible for tachometer to show 4k rpm when speedo is showing 60 kph. That's because tacho is slow and needs longer time to show the actual engine RPM.

In Pulsars the engine is as high raving as apache. But Pulsars have lazy tachometers which gives impression as if engine is slow.

At what RPM what speed expected is can be calculated by a simple formula. No matter bike has run 0km or a million kms, that formula gives constant answer. It's simple maths. You don't need to prove anything. If your console showed 60kph @ 4k RPM for prolonged time then consider that your console was faulty.

I believe you're saying engine is knocking at lower RPM. That's expected considering you're running rich AFR tune meaning more fuel is being sent in with less than required amount of air.

Rich AFR also causes high CO numbers. Too much petrol means explosions happen at lower temperature than necessary. Lower temperature combustion means Carbon Monoxide(CO) isn't burnt into Carbon Dioxide(CO2) so large amount of hazardous CO coming out of your exhaust.

Use of the high octane petrol isn't a permanent solution.

Re: One help needed

use normal fuel, thats sufficient.. and even i have noticed a difference between bpcl and indian oil.. and i find bpcl better, the bike feels smoother and returns around 1 km more mileage for me while some others have reported 2-3km more mileage..i ve had the same feedback from a few colleagues at work too.
this is in hyderabad, and the two indian oil bunks under question are located at Madhapur and one at hitec city near cyberperl.

Re: One help needed

I have Pulsar 180 UG4 ,purchased on Nov 2013 ( manufactured in oct 2013 ).

clocked 2000 km on odo.

I am constantly getting slightly below 40 kmpl in city driving. my average speed for month is above 65 kmph. I drive at 65-70 kmph at 5k rpm , somtimes crossing 6k rpm at 80-90kmph.
measuring fuel efficiency :- full tank + some reserve = 12.5 ltrs (or Rs 900) approx refilled every month ( 475 km on tripmeter ).
No question of petrol quality its the most busiest and trusted petrol pump in the east delhi

Since this is a twin spark plug engine and both spark plug works simultaneously between 4k to 6k rpm,

when at 5k rpm and above 65-70 kmph; engine noise should not be unpleasant in this range ( i feel like i still have a gear change left ; that kind of noise ). I follow gear change ratio strictly as mentioned in the user manual.

whereas when accelerating slightly hard or crossing 6k rpm , engine noise is more refined and pleasant to hear.

I have done first service only, running everything stock.

Only got idling rpm changed due to cold start problem ; 1350 is the recommended for a warm engine ( 5-6km running ; 40 deg C oil temperature ) but i get around 1500 at warm engine ( its not possible to get engine sufficient warm after 3-4 hours waiting at the service centre )

I am not in favor of getting my engine touched by a mechanic ( not expert ) until its compulsory, just for noise problem.

So, is my fuel economy good or is there some scope of improvement ??

regarding engine noise any opinions ?? i am planing to change engine oil to MOTUL as i have read in several posts in this forum . can it help with engine noise reduction ??

Thanks

Just for one tank don't cross 4000 rpm while changing gears. Even on 5th gear then check the average.

(You should be getting higher kmpls, acc. to me, like 45-48 kmpl since the day you took it out... and after that its "your riding conditions that change the mileage values". I myself got a mileage of 48 49 ish when i took it out and in between i scored a 52-53 kmpl at all conditions (with a slight engine lag) but now i'm getting 42-46kmpl in all conditions with no lag or anything.
Secondly, dude you're just 2000kms old on your pulsy and you're sayin that "I follow gear change ratio strictly as mentioned in the user manual." and you've "sometimes reached 65-70-80-90 kmph" then that's IMPOSSIBLE...!!! that for the slightest bit you're even caring for the engine coz till 2500 km you should not be going above 65kmph as your bike is in run in ( theoretically its 2000 kms for run in) and attain higher speeds like 90s like once, twice or max thrice... personally during run-in i took it to 96 once then 83 and then 87 kmph all within an interval of 2-2.5 weeks and i completed my runin in like 2 months or so... so its a humble request with PLEASE...!!! STOP RIPPING YOUR BIKE...!!! )

No question of petrol quality its the most busiest and trusted petrol pump in the east delhi.

(Umm... Just being the most busiest petrol pump doesn't guarantee the best petrol or the promised price-quantity petrol... "agar dandi marni hogi toh marenge hi, just imagine if they even if they prick like 15-25 ml from each customer whether on four or on two wheels, how much profit would they make IF "its the most busiest and trusted petrol pump in the east delhi." and for quality no one's coming and doing QC coz no on has either the time or interest for it... so its just some people who actually make pinpoint measurement of quantity and quality and that too by patient riding...)

Since this is a twin spark plug engine and both spark plug works simultaneously between 4k to 6k rpm, (Correct)

when at 5k rpm and above 65-70 kmph; engine noise should not be unpleasant in this range ( i feel like i still have a gear change left ; that kind of noise ). I follow gear change ratio strictly as mentioned in the user manual. whereas when accelerating slightly hard or crossing 6k rpm , engine noise is more refined and pleasant to hear.

( don't worry its completely fine, even i used to feel that there should be a sixth gear too, but after some time like after 4500kms i never never felt the need for another higher gear, REMEMBER its just 2000kms old...

)

I have done first service only, running everything stock.

Only got idling rpm changed due to cold start problem ; 1350 is the recommended for a warm engine ( 5-6 km running ; 40 deg C oil temperature ) but i get around 1500 at warm engine ( its not possible to get engine sufficient warm after 3-4 hours waiting at the service centre )

(No Comments, for this ask @lockhrt999 (locky 'tippani' please), i'll tell you my condition from Lucknow, even in the coldest of temperatures my bike starts with a single crank at 1000 rpm and within 5 seconds i pull the choke for attaining the optimal engine working temp. (as told by locky in one of his posts how, why and when) and when the engine is super heated like run really a lot then the rpm is 1.25k - 1.3k or max at 1.35k... and till date i am facing no issues with starting

)

I am not in favor of getting my engine touched by a mechanic ( not expert ) until its compulsory, just for noise problem.

(That's a really good attitude and always get your ride serviced in front of you no matter what the SC people say... if they refuse to do so, fire a complaint BUT if your gut feeling says that something's not right then take it to the doctor and get her diagnosed IN FRONT OF YOUR EYES... )

So, is my fuel economy good or is there some scope of improvement ??(Definitely there's a scope for improvement and it SHOULD improve... as they say "It's never too late..." ask Taahir he is getting mileage of 50+

)

regarding engine noise any opinions ?? i am planing to change engine oil to MOTUL as i have read in several posts in this forum. can it help with engine noise reduction ??

(Observe a bit more, coz see during these 2-2.5k kms bikes undergo like the "HORMONAL CHANGE" so your bike is still in its puberty period so maybe its an effect of that but yes definitely be alert, if something's not feeling good get it checked... as for now i can make a guess that it could be requiring tappets adjustment at the max... and its completely normal
Use onomatopoeia for that matter...)

For MOTUL i think its too early and you have just got your first servicing done so i suggest you to stick with bajaj oil coz i have personally seen claim cases not being entertained just because they changed their engine oil too early and one of them was a MOTUL even though the mechanic accepted his fault. so up to you... enjoy the warranty get the tappets adjusted)

Yes, MOTUL is a really good oil and i too have seen the difference personally as my friend sgsarthak has just got MOTUL filled in his 4th service and his bike has become a charm now... but still i think its too early for the bike.

Thanks (You're Welcome Bro)

You probably didn't measure the average the right way or you were tricked on the petrol pump by putting less petrol in the tank.

Always measure the fuel average using full tank method only.

Re: One help needed

FE is okay, but the problem is the rider, he is not running in as mentioned in the manual but that should be okay. To measure the average, use a 1 liter bottle and drain the carb before riding, that's how you'd get the accurate FE.

You need to set the idle on a warmed up engine, not on a cold one, ride your bike for 5 kilometers and then set the idle, it is easy, you don't even need any tools for this. Just adjust the idle screw with hand. Somebody please post a picture of the idle screw here, I don't have a Pulsar 180 so I am not able to do so.

Anyway, your bike is fine. You are just in the process of getting used to a new bike.
