Re: Bajaj Pulsar 150 All Versions

Yesterday I went to ASC and told them the problem, They told there is not any problem with Spark Plugs, They tuned the AFR Screw and Idle RPM Screw and told me that the problem will be solved..........
But I don't think the problem is solved yet........
Today I will visit them again and will tell them to check Battery and Spark Plugs and tune the Carburetor again...............

Thanxx everyone for your help......

Re: Bajaj Pulsar 150 All Versions

Bro can you help me and tell me how to remove Spark Plug and How to clean and reinstall them, What tools are required and all that, I don't know anything, Plzz help

Re: Bajaj Pulsar 150 All Versions

Bro I suggest you to take it to local mech. I will post a video anyways for that. Spark plug head can be washed with petrol and tooth brush. Thats the way I do it.

Okk bro, plzz post the video...........

Re: Bajaj Pulsar 150 All Versions

Hello Friends,
Can anybody tell me the optimal factory setting of the AFR screw (From fully tighten position)of pulsar 150, will be servicing my bike in around 2-3 days so want to adjust it to factory

Re: Bajaj Pulsar 150 All Versions

Here you go : Pulsar idle speed tuning - YouTube

You can go through the video and check how to tune the AFR. Still I will suggest to leave this job for mechanic, because if you don't do it properly you will run on either lean or rich which will end up harming your engine.

This is not of Pulsar 150 but it will give you the idea of how to take out the spark plug and it is at the right side of your bike.

Re: Bajaj Pulsar 150 All Versions

Hello maadyy, thanks for the video but is for idle tuning(increase or decrease ) and not for the AFR (air fuel ratio) adjusting which is the small golden colour nut in the carburator..
Thanks

Re: Bajaj Pulsar 150 All Versions

Bro check this thread you will get the desired AFR rotation number. It is posted by somebody long time back. But ideally when you perform the idling you get the perfect AFR tuning. Setting of AFR depends on your engine condition and the running environment. Turning the AFR screw anticlockwise richens the mixture and turning it clockwise makes it go lean. My factory settings was something 2.7 or 2.8 but it changed later (1 turn = 360 deg rotation of the screw). If you miscalculate it, you are screwing up your engine. There are 'N' number of facts which makes every engine behave different from one another like the type of engine oil used, air filter, altitude from sea level (location), fuel quality etc etc. So i suggest to leave it to your mech for the best tuning. I was running on something around 1200-1400k RPM now its around 990/1000k RPM, that is the change I did when I changed my piston bore kit before that it used to be idle on around 1100/1200 and I kept that a little higher.

Regarding cold start problem of my bike,
I went to ASC, they tuned the AFR screw yesterday, In morning when I started my bike, it got started within 1 kick even without using Choke...
so that problem is solved by tuning the carburetor but after then I am feeling a low pick up problem, Pick Up seems to be a bit low.......
What can be the problem ??

Re: Bajaj Pulsar 150 All Versions

Bro it's not exactly low pick up problem but you must have been in rich mixture earlier because of which you have experienced a sudden thrust in throttle now since it is idled perfectly you are missing that thrust. I have the same experience with my bike. You can try adjusting the clutch and accelerator cable by asking your mech. What is your current RPM now? Also check your spark plug tip colour if it's black or brown.

Re: Bajaj Pulsar 150 All Versions

After watching the Video I removed the Spark Plug, It was something Brownish in color, Not Black or dark black, I forgot to take the pic but I am sure it was brown in color, there was no oil on the spark plug, It was dry, I cleaned that using sand paper and kerosine oil (Although it was already very clean still I tried to clean it a bot more) an then after some time I reinstalled it..........
Took a ride of 1-2 Km and checked that again, It was still brown...........
I think the tuning is perfect, Idle RPM is between 1-1.2k, When warm it idles at 1.2k around and in morning it idles around 900-1k

Thanxx 4 ur help............

Should I try cleaning AIR Filter also ??

Yesterday I calculated the Average of my bike using Reserve to Reserve method and it was something around 44-45 KMPL, Maintained the speeds of 40-60 always even though I got this, seems a bit low to me, It was done after tuning the AFR............

Re: Bajaj Pulsar 150 All Versions

If its light brown then its okay. 1.1/1.2 k RPM is okay. You can't change the colour as it comes into colours after getting burned. If any oil were there in spark plug that would have stopped or given you problem while starting your bike. Because if I am not wrong oil is a bad conductor of electricity.I am getting the same mileage as of you. The reasons are:
1. I am using fatter rear tyre.
2. When you are fueling make sure you are getting the right amount of fuel for which you are paying. There's a slip itself of the machine from which fuel is provided , the machine generated slip which will give you the exact amount of fuel given to you. Ask for that slip , that will ensure you if you are getting the right amount of fuel. Mileage also depends on the quality of fuel you are using and your riding condition, as in if you are riding more in highway your mileage will be little more than that of city.
3. You check your air filter if it's too dark I will suggest you to change it, it will cost you something around 40 rupees.

Ideally you should get 50 as in minimum mileage provided you don't use your clutch extensively something that happens when we are riding mostly in bumper to bumper traffic. Well Pulsars after using 2-3 years returns this kind of mileage if I am not wrong your one is of 2011 batch, so it is okay kind of mileage for that. You can also check with Pulsar riders in your locality.

Black colour means you are running rich, dark brown means you are running lean, light brown means it is okay. nothing to worry about that. As I have mentioned if your bike is of 2011 batch then nothing to worry keep munching miles and do service at regular interval. Try if you can use same fuel bunk for filling up your fuel and drain engine oil at regular interval and try to use same brand and same grade of engine oil. I believe this will keep your bike in healthy condition. So enjoy your ride.

Re: Bajaj Pulsar 150 All Versions

One of my friend also has same pulsar 2011 model, He says he is getting the mileage of 50kmpl
Next time while getting my bike serviced I would tell the ASC guyzz to check and increase the mileage if possible :P

Bro do we have required tools in our default tool kit that comes with Bike to open Air Filter Box ???
One more question, I have SAE 90 grade gear oil, I use it to lubricate chain, I have read somewhere that we should use 90 grade gear oil for Oil filter lubrication also but some members say that we must use 2T oil for lubricating Air Filter, Can you help me ???
I am having 90 grade gear oil ( 1 liter) whereas I would have to buy that 2T oil if required............

Plzz help me which Oil to use if we want to clean air filter at home, Where can I get the new AIR Filter and what would be it's cost ??

Re: Bajaj Pulsar 150 All Versions

Open the right side panel with your ignition key, then use the screw driver given in the tool to open the box. I suppose 4/6 screws are there. You can then take out the air filter. It has a fiber dissection in between sponge air filter. take that out, but be cautious while putting the new air filter coz you need to use that fiber panel to insert the air filter. For lubricating you can use Motul chain lubricant, its good. If pocket permits you can use Motul chain cleaner also. Chain can be cleaned otherwise with the help of brush or chain cleaner brush to be specified. You can use petrol to clean the air filter.

You may check this for any kind of Motul chain cleaner or lubricant.

Re: Bajaj Pulsar 150 All Versions

Friends, Yesterday bought the oil, but since the motul wasn't available gor the castrol GTX 20w50 but after coming home i realized that it is a car oil so is it safe to use in my pulsar 150 UG4.5
