Re: Pulsar 180 UG4 default carburetor setting?

2.5 turns is default. I recommend tuning it correctly.

Re: Pulsar 180 UG4 default carburetor setting?

Finally a reply😊thanks a lot.. 2.5-3.5 turns should be fine right? Anticlockwise from zero tight position?

Re: Pulsar 180 UG4 default carburetor setting?

IS it digital model UG3 or UG2?

Before actually tuning the carburettor please verify the Pilot and main jet screws diameter in mm are same for both the models.

Full turn clockwise (tightening) and screw will not tighten further (be careful not to use full force)---> Lean setting. Air is more fuel is less. Plug will show whitish deposit on electrode
Full turn anticlockwise (screw will ultimately come out from carburettor) ----> Rich setting. Air is less fuel will be more. Plug will have soot or become black.

1. First clean both plugs thoroughly.

2. Tighten fully the screw(clockwise). Dont tighten too much. Then to make things easier for you, just unscrew (anticlockwise) upto 3 full turns. Start your bike and ride for 2 days or some kms in your city thoroughly. Feel how your bike responds while starting, idling, pickup. If its ok then check plug , it should be brownish to some what blackish brown. Check for idle plug colour in google.

3. As per my experience with Pulsars plug will not turn either black or white at 3 full turns

4. 3. If your plug seems White , then further open the screw 1/4th turn (total 3.25 turns) and again follow step 1 and riding thoroghly and check ing plug colour.

5. For me 3.5 turns worked best for me. But for your bike you have to check that thing.

Some points.

--Bike silencer should not give popping sounds while going downslope roads, indicates lean mixture.
--Bike should not overheat than regular, which indicates lean mixture.
--Bike should not give black smoke and you should not notice drastic low fuel efficiency , which indicates Rich mixture.

Hope this helps

Hi srinivas,
Yes it really helped me a lot.
Thank you so much for the step by step writeup..
understood each and every step..
My Pulsar is 180dtsi non digital model.

I will go through the process and will reply soon..

Thanks and regards

Re: Pulsar 180 UG4 default carburetor setting?

I believe you had also purchased new "carburetor intake manifold rubber"(The rubber connecting from carburettor to Engine head). Google it if you dont know about it for pictures. If not the first thing to but is new manifold rubber which costs nothing when compared to carb cost. Many mechanics take it lightly.
Overtime the rubber hardens due to heat and produces leaks.

To further make the tuning perfect, there should not be any petrol moisture/mud moisture at manifold rubber which will show after some days if the rubber is faulty or if it was not tightened properly or if its a wrong model manifold rubber(happens when you change rubber and if it doesnt match your carburettor, once happened with me) .
If theres some moisture like thing , it means the petrol+air mixture is leaking which will never ever make your tuning perfect. and also it should be tightened good. Trust me on this part.

Also similarly the carburettor must be tightly attached to Rubber from filter box. Many mechanics will not tighten it properly because its somewhat difficult to reach in Pulsar and with small turner screws and most mechanics will not do the job. Its very bad and it will suck dust from outside environment and in the end the tuning will not be perfect and there will be clogged jets etc.

Re: Pulsar 180 UG4 default carburetor setting?

Hi srinivas,
Very very useful information again, yes what you said about the manifold rubber is very true.. But the rubber was purchased recently I mean like before a month or two.. As of now I don't see any such problem but point not to be ignored😊👌
Will surely check this again.. And keep this post updated.. The carburetor is now tuned to 3full turns.. looks smooth and fine with better pickup as well..yet to check the spark plugs after atleast running for about 100+ kms for better results.. 😊

Thanks again srinivas 😊

Re: Pulsar 180 UG4 default carburetor setting?

Ride your bike thoroughly. Also observe the bikes heating. Yours is UG2 with kick starter right.?? Ohh,,,

I am assuming you are using good oil with around 3K kms change interval and not just topping up.

Try this one thing.

Ride usually your bike in your town or city thoroughly for some good 10-20kms or even more (I have literally tried driving long distances) and try to hold the CURVED PART of kick starter rod. It should not get HOT and should be very very mild warm.
If its hot or very warm then your tuning is not perfect.
I have literally tried many settings observing my bike symptoms carefully. When the bike is in lean setting the kickrod used to get hot and you can trust me on this thing.
If your bikes kickrod is getting hot, i suggest to further open your screw by 1/4th turn at a time and re-check.

Now as you said at 3 turns your bike is behaving good.
You should not feel that your 1st gear is too short i.e; your bike is screaming/missing when you accelerate little bit in first gear or in any gear.
Better the setting, you will get better feel in each gear.
Also try to quick accelerate your bike to 70-80kmph(only if possible and dont take risk) and your bike should not make drama. What i mean is it should accelerate quickly.
UG2 are kickass machines as far as my experience is concerned. the pull is quiet good when compared to UG3.

What i have written are my own experiences on my Pulsar riding more than a decade and i have not taken this from anywhere. But i am sure you will get your tuning perfect.

Re: Pulsar 180 UG4 default carburetor setting?

You could keep it at 3.5 turns and forget about it.

Or you could go by feel of the buttocks and tune, basically when the motorcycle is warm hit the highway with a tester and crack open the throttle and pin it to WOT, now gently roll back on the throttle, if the motorcycle pulls harder when you're closing the throttle stop and open the screw 0.25 turns and repeat the procedure until you reach a point where the motorcycle stops pulling when you roll back on the throttle from WOT.

As for finding air leaks, when the motorcycle is hot, raise the idle to around 3k RPM and then spray WD40 around the carburetor, if there is a leak when you spray near it, the RPM will shoot up.

Cheers!

Re: Pulsar 180 UG4 default carburetor setting?

Hey Ashwin,
That was really helpful input, will go through the process and try to put it in best condition.. Will keep the post updated once I notice some changes.. It really helps😊👍

Thanks and regards

Re: Pulsar 180 UG4 default carburetor setting?

Hi Ashwin,

Good points. Yes 3.5 turns works best and WD spraying is accurate way as you have said.

little OT: Mods please apologize

I read your posts whenever a come across a thread and your explanations are quiet informative. Huge Thumbs up from my side.

I have read your bike trips on your Karizma and CT100B and enjoyed thoroughly and learned that to avoid having energy drinks often during trips on a bike. I have modified my Pulsar UG2 handle with Discover 125 handle many years ago and long journeys has been incredibly enjoyable without any strain and surprised to know that you too changed the handle of P220. maybe we are like minded giving priority to riding stance and comfort.

If you dont mind, a few questions:

1. Is there any specific problem that you have sold your ZMA? i know that there is spare parts issue and insane cost of spares.

2. you want to go on a tour or ride normally, you often write that P220 bores you? May i know what you mean by that.? I agree that riding a low capacity engine is easier and less stressful.

3. Is P220 still relevant in 2020 and now it is coming with FI. How would you compare P220 with P200NS FI/BS4 in terms of ease of maintenance? Would you still recommend it over P200NS?
I feel that P220F is better to ride in cities, towns and in tight lanes as it has only 5 gears and requires to shift gears lesser than P200NS. But riding stance is better as i have felt on Pulsar 200NS
Please share your thoughts.

Srinivas

Re: Pulsar 180 UG4 default carburetor setting?

Had the P220 and ZMA when I completed my course, due to nuisance from extended family for being jobless and owning 2 motorcycles I sold off the ZMA, regretted it cause it was my first motorcycle.

But from a practical stand point, Bajaj is like the Black man's penis as far as the White women are concerned, once you go Bajaj, you never go Back!

Jokes apart, the quality of metal and plastic used in the motorcycle is commendable especially considering the price at which they're sold, I can point of sections of the P220's ownership which my ZMA would never match up to, but one thing that cannot be argued is that the ZMA had character which is something the P220 lacks, it does everything better than the ZMA as far as my use goes, but it simply lacks the character.

The P220 is a really boring machine to ride(especially in KL Roads), it gets the job done with class leading reliability no doubt but there is absolutely no fun involved.

CT100B on the other had is Teeth Grinding fun! You can pin that screamer to WOT for hours at end and it'd still be as engaging as it was when you got on the saddle, on the P220 it takes mundane effort to not fall asleep.

Absolutely polar machines, P220 has a solid mid end whereas the NS200 has an amazing top end.

Going by rule of thumb I stay away from Liquid Cooled machines, my P220 has been leaking oil from the head since she's turned 10k and now she's at 60k and I've been ignoring the leak from the beginning, still runs beautifully with some oil drop due to the leak but since I'm a fan of early drain intervals(1500~2000km's) it is not even a bother.

If I had the same on the 200NS or any liquid cooled motor, forget riding 50k km's, I'd not even be able to go a 500 km's before the motor seizes.

If you already have a previous gen Pulsar then don't bother buying a P220, you could simply upgrade your current Pulsar to a P220 for peanuts.

This is a P220 at heart;



Alloys, Dual Discs etc would be added in the near future.

This costs peanuts compared to paying close to 1.5L for a brand new P220 in 2020.

As for P220 vs 200NS, both are polar machines and its really hard to compare them, so better for you to ride and choose if you do not have any other determining factors, the 200NS handles leaps and bounds better than the P220.

Personally I'd still stick with the P220, cheap to run, easy to fix, bloody reliable!

Re: Pulsar 180 UG4 default carburetor setting?

Really thats great of you for taking time and answering my queries.

haha.. You have nice sense of humor man. If you were in Hyderabad, i would have definitely meet you


Many of us might have gone that phase of not having a job and family(especially outside) poking us everytime. thats sad.

As you pointed out clearly in some categories Bajaj bikes are really serious in what they offer and very few can match them at the price they offer.

One of my close friend has ZMA(He bought 2 of them normal ZMA and later ZMA-R) and later he had sold it off due to non-availability of spares(genuine), we had fun on it and long distance touring is a bliss on it.

Your thoughts on P220 as an owner are similar with what i have in my mind always.

The liquid cooled engine even though great, with their performance but to maintain and to find a good service centre with good mechanic is always a headache.
And that engine wall cracking and coolant mixing with engine oil is always a surprise for me. If it happens in middle of a tour (especially in our country) GOD save us.
Here in Hyderabad servicing a liquid cooled bike is like a Jackpot to the service centres either its ASC or Outside mechanic.

Forget about the towns and smaller villages. You wont believe that a City(as status)(name is Eluru) (West godavari district headquarter) in AP state, you rarely find a liquid cooled engine bike. Its not like that they cannot afford but its the availabilty of spares, mechanics and service centers and the tech that puts them away from people. and P220 its everywhere. and here in Hyderabad both P220 and P200NS are on roads and obviously P220 have higher numbers.

The picture you shared of P150 with swingarm, 220 engine? right bro? Please share the link and details if possible. Hatsoff to the idea and that guy

I literally like touring on bike and done touring like 500kms+ on my Pulsar150 UG2, but on the same route always. Its damn reliable.
Many may argue that Pulsar is not that reliable. But you know what? I have once ridden it at 80-95kmph literally for 100+Kms non-stop in a 500kms+ trip without taking break and there is no drama of burning smell or any other kind from the bike. generally i would take break after 60-70kms non-stop.
Without being reliable can any bike sustain such torture??

Touring relieves the stress that gets inside is what i believe. But i wish to tour like you exploring new places.
Really you are one lucky guy Bro, really very very Happy for you. I really like to read the touring trip stories of yours.

As you have achieved touring the Golden quadrilateral, Wishes from my side bro. One day i wish to travel like you
