Re: One help needed

@Cleaner Aye Aye Captain... here you go...!!! The one with the spring just in front is the Idle Rpm Screw... and don't unlock any unlock these screws... just touch the spring wala screw...

Re: One help needed

1. The method you used to measure FE is not the right way. For exact reading, disconnect the fuel tank's supply to carb. Purchase the petrol can with tap and fill it with 100ml and ride around. Start taking readings from 2nd refill. You will get this equipment at most spares stores. Drive at different rpms and ensure to make a note of readings. You can come back home and do calculations.

2. Again, idle rpm and tuning should be done on warm engine. 1350 rpm on cold engine will certainly go up. Not right. Before tuning carb, ensure you have clean filter and oil. I feel it is too early to lean out carb mate. Maybe around 5k kms when internal components bed in.

3. Engine harshness is expected. I am sure it is running on bajaj oil. Are you interested in SS or FS? I would always go with good mineral oil and change it every 2500kms. If SS or FS, change over after run in of probably after the 3free service.

How you ride your bike now, determines how the bike will take you for a ride later on. Hold your adrenaline, just expect the average and always remember it is a new motor. Good luck mate.

Re: One help needed


Thanks for response.

Whenever i go for refill i have only 0.5-0.6 litre in tank ( reusable reserve ). distance's dont favor me to go beyond that amount of petrol.

i reset my tripmeter everytime i get full tank.

Mileage stated was fairly consistent even after 3 tank fulls ( every 474 kms). one tank full was from different pump.

I drive 20 km per day ; 100 km per week.

I idle the engine for about a minute in the morning and evening ( after 6-8 hours of standing ) , before start moving, to bring the engine oil in circulation.

Cold engine rpm is 1-1.1k . by factory it was set to 900 ( that gave me cold start problem ). it is around 1.4 to 1.5 on a warm engine, its fine with me, because i don't encounter start-stop traffic in my route. its just minute long traffic lights where i turn off the engine.

Measuring fuel efficency : when i go for a full tank i only have 0.5-0.6 litre of usable reserve, i set the tripmeter to zero. then i get a full tank, note the amount refiiled and tripmeter reading untill next fill. it has been fairly consistent over last 3 tank fulls. i am able to drive approx 474 kms before heading to fuel tank ( when its absolutely necessary).

20 km ride per day, 5 days a week.

I will use the 1 litre method, after sometime as its not so important for me to know the exact value.

Still running on bajaj oil. i have read in this forum that SS or FS oils accelarate the engine seal lining decay in pulsars. Thats why hesitant to change the engine oil for now.

Kindly read my two other replies with this post to know the details of my fuel consumption and idling rpm.

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


Kindly read my other replies associated with this post to know my further comments.

Regarding petrol pump, its good. no doubt on its quality, otherwise i would have heard negative comments on it from my friend bikers.

I reached 100kmph only twice that too for a minute or two. Got excited

Otherwise i max out to 80-85 kmph only

Fuel efficiency is not such an urgent issue with me, otherwise i would have gotten a 100cc bike :P

i specially take half day from office to be with the bike while its being serviced. it also teaches me various things about how to remove various parts, while observing the mechanics there.

2nd was done @2800kms, 90 days after the first.

right now, i have completed 4000kms

Bajaj Pulsar 180 UG3 engin noise

Hello fellow Bajaj Pulsar owners

I have a "pinging/ratteling" noise when I drive steady speed anything above 50km/h and just letting the throttle off a little bit. Other then that the engin is fine. I have checked the valve clearance and they are in spec. Even have the sound after an oil change. I will only clean the oil filter in the next weekend or two. I cleaned the carb and replaced the slide, diaphragm and spring.

I use:

Oil: Motul 3000 20w50
Spark Plug: NGK CR9E
ODO: 20 000km

Any help will be welcome....

Re: Bajaj Pulsar 180 UG3 engin noise

Exhaust condition and bolts?

Re: One help needed

Again, Replies In BOLD...

Re: Bajaj Pulsar 180 UG3 engin noise

Exhaust is still in good condition, I also rechecked all mounting bolts with a torque wrench. I also can't reproduce the sound when the bike is on the centre stand and I rev it.

Re: Bajaj Pulsar 180 UG3 engin noise

Alright. Do the servicing on 5k. and at every 3k kms after that.

On the most pulsars the black dial around the keyhole vibrates after certain engine RPM and it does make pinging noise. To test this, when that noise starts put some pressure on that dial using your left hand and see if the noise goes away.
If it isn't that check for loose nuts and bolts etc.

One more thing that oil is good but being mineral it doesn't last more than 1.5k kms. It may last 2k kms on your roads but no more. Use semi synthetic at least like Motul 5100 if it's available there.

Re: Bajaj Pulsar 180 UG3 engin noise

Just follow the checks that [MENTION=25280]lockhrt999[/MENTION] mentioned... if you find the point then well and good else confirm me the sound, is it like 'trrrrrrrrr' sound and feels like coming from just below the tank when your accelerating regardless of a pillion, if it's a yes then get your "Rocker Arm" Checked, it should be that... coz you also mentioned that you've checked all the nuts and the bolts but still the sound persists... also I wud like to mention that its a sound like a nut is vibrating...

Re: Bajaj Pulsar 180 UG3 engin noise

I did what [MENTION=25280]lockhrt999[/MENTION] mentioned with the key ring and the sound are still there. Just for me to found the Motul 3000 20w50 was an issue in this place, even the agents wants sell you normal Castrol Activo 10w40 because that's what they use and they say it will be fine. I am more on the side what the manual tells me regarding oil.

prajwalmd the 'trrrr' is what I am hearing under the tank, but not when you accelerating only when you let off the throttle just a bit. When I think back the sound came more or less when I replaced the carb diaphragm, piston and spring as a complete set. I made sure the the E-clip was in the second from top position as mentioned in the manual. I had a bit of time this morning coming to work and I can reproduce the sound at a specific throttle position, saying that I also checked the reed switch with a multimeter and I can confirm it is working. Bike also starts with no problems. I am reluctant to take the engine top off to inspect the timing chain, because it looks to me if I loosen all the nuts ontop of the engine I will need a complete gasket set for the cylinder head that I don't have at this moment. Can anyone tell me if you remove the automatic cam chain tensioner, how much pressure must the cam exert?

Re: Bajaj Pulsar 180 UG3 engin noise

Don't use w40 oil in pulsars, it will kill the engine as pulsar engines run hot. They need w50. Valvoline is another tried and tested oil on our engines, see if you can procure that.

Before you go and open the engine again, consider another scenario. In P180, P200 (old) and P220, the drive chain rests on the swing arm at a location(near your left foot) when tension from the chain is released (that is > when you release the throttle). So that sound might be chain rubbing on swing arm rubber casing when you let go of the throttle. This sound will go away when the engine is pulling the bike. If this is the case then you need to lube the chain and adjust its slackness.

To know details about engine parts you asked, calling @Cleaner, tring tring.

Re: Bajaj Pulsar 180 UG3 engin noise

I'm here, thanks to the tag by [MENTION=25280]lockhrt999[/MENTION] If you are just taking off the rocker arm cover, you can reuse the gasket. The gasket is reused all the time, even by SVCs because it would be inconvenient to change the head cover gasket every time they adjust valve clearance. BTW from the symptoms you described, the cam chain tensionier may need replacement. I assume the sound you are talking about is like the vibration of cellphone rather than the sound of metal being turned in a lathe. BTW post a close up picture of your chain sliders too.

Re: Bajaj Pulsar 180 UG3 engin noise

thank for all the replies so far. i will look at the rubber chain slide. my chain is clean, but nothing wrong in lubing it again. Will take pic's on the weekend and post it.

The closest i can tell you precise what it sounds like is to take metal BB balls and put them in a tin can and rattle it. I just stumps me that it just do it at specific throttle position. I am still scared about the rocker cover, but that will be my last resort.

Re: Bajaj Pulsar 180 (All Versions)

Yes the bike becomes more smooth when you use bp petrol my bike has become smooth when I have changed it from Indian oil
