Re: Bajaj Pulsar 150 All Versions

Thanks for your inputs man.
I'll upload another one of riding sound and it's pure eargasm.
The sound is looking like a pop because I held the phone too close to the exhaust.
Actually I used two phones but the audio of lumia was a little high pitched and unnatural.

Although the bike does pop very rarely on a hot engine.
Spark plug comes out reddish brown every time.
And in 5 years of ownership I've never faced a cold start problem.
You're spot on about DC ignition the bike just starts with a bang no matter what weather or how long it's kept idle.
I can barely even hear the starter motor spin unlike my friends UG3.

The reason for the good exhaust sound is because my bike was mostly used on highways.
Dude enlighten us more on the electrical capabilities of pulsar.
I have no clue what this beast can do(Ironically I'm an Electrical Engineer)

Re: Bajaj Pulsar 150 All Versions

Hi Art,

not to oppose you.. But Pulsar stator coil is generally a good winded one.. But ont know whether its winded by hand or by machine... My 10 yrs old Pulsar UG2 is an example of it..

may be your one has a problem i think...

For your knowledge and long long discussions that has went on "Make bike full DC" thread... maximum ac voltage reported in many bikes rewonded stators (Uni. apache etc) was in and around 70-80 volts max ac from all the poles rewinded...

Some even said that pulsar magnet is weak and unicorn magnet is strong and so on.. i donot say pulsar is great or waste... let me give you readings...

Just plonk in AVY180 original stator and just check the 3 charging poles.. u will get 75+ volts max ac... No kidding here... That means just 3 poles voltage is exceeding the above bikes total rewounded stators.....

then what will be the total 7 poles ac voltage of normal avy stator ...?????

i have rewounded the avy180 stator and the voltage crossed a whooping 120-130 volts ac and i have never heard of such huge voltage atleast in this forum.. i have checked with two Dmms... Its a fact..!!!!

so dont underestimate your Pulsar...!!!!

"my pulsar always had starting problem using kick lever even i had to press self longer to start it"

no Honda can start with a single kick... but Pulsar will start in a single kick.. Please inquire it anywhere...

The longer time for the bike to start during self operation for bikes upto UG3 is due to: when you press self the magnet should rotate enough around yellow(ign) coil to produce high voltage then transfer it to CDI.. there multiply the voltage and then the spark will be produced... UUUfffffffff... but the kick will be strong enough to produce that effect....

From UG4... just press the self the current goes from battery to cdi.. then bang...!!!! this is what makes the self of UG4s a feather..!!

Theres no way to make the bikes upto UG3 self smoother.. only way is to make DC ignition and its not a hard job....

Adv of UG3 over UG4: If your yellow coil and pickup coil is good.. nothing is needed in your bike to make your bike move..!!! but UG4 the battery should be good and AFAIK the RR should also be good for a bike to start...!!! The DC cdi of pulsar AFAIK doesnt contain any ac to dc conversion mechanism..!!!

As for your inquiry:

I have checked voltage of lighting going max to 13.2-13.3-13.5 v volts max (from RR).. and if we throttle more the voltage reduces and voltage will not be constant and fluctuates like crazy.. may be shunting effect i guess..

For charging the voltage for UG2 UG3 (both are same) never crosses 13.5-13.8v DC voltage(from RR)... But using a AVY stator and AVY RR the voltage goes upto 15.2v(from AVY RR). As i stated above the ac voltage from AVY stator crosses 75v+ ac from charging poles and for the lighting its the same 13.5-13.4volts fluctuating ac..!!!

The ignition coil as i said in previous post surpasses whooping 200+ volts ac.. but i didnt checked at a particular RPM...

The controlled voltages from RR i stated above is max.. it will not go beyond it...

But as for ac is concerned i max rev the bike around 7-8 RPM and i never throttled to the top.. you know the reason... houses and families in and around and also not good for electricals while bike is not moving...!!! If i had revved to the top may be results will be more than i stated above..!!

befor finalising on your ignition coil.. Please check for CDI, Black coil(pickup coil in stator) (should produce around 2 to 3 to 4 volts ac may be 3-4 is max) and finally High tension coils (which gives current for your sparkplugs) black/white coloured.

CDI check is must..!!! it is mostly culprit...!!!

cheers,

Did i made bore..??? haha...

Hi dude..

At the end its popping sound right...??? May be a lean mixture (more air)....

may be you know it but i will pen down it... to confirm it go to a hill uproad area.. ride down your bike down hill.. engage in 2nd or 3rd gear or higher gear.. just leave it and dont throttle or engage clutch... if you observe popping sound it is definitely a lean mixture.. also you to determine it by seeing plug...

I can also tell my special way ... lean mixture pulsar bike will be hotter right..??
to know it ride around your city for a good amount of time... more than 30 minutes... now try to hold the bottom of kick rod where there is a curve... you should observe a no heat/medium temp that you can feel comfortably... but not a high/hot temp.. you are getting what i am saying right..???

in the other cases it may be worn out silencer.. but i think your bikes silencer is good...

Hi Suman...

nothing to worry.. it is may be due to static electricity...
just google it.. No worries.... Cheers...

Re: Bajaj Pulsar 150 All Versions

Hello guys this is my pulsar's exhaust sound on warmed up engine.
Looking forward to your comments..

Re: Bajaj Pulsar 150 All Versions

Thanks today I noticed a weird problem. While riding to nandi hills at some point of time fuel got over and while riding itself when I turned the fuel knob to reserve it gave a sudden electric shock. I just got confused wats tat.....tts no effect to bike but I don't know y it happened and now I am afraid to turn the fuel knob while riding as I am frightened that again if it gives an electric shock,..,...wats tis huys

Re: Bajaj Pulsar 150 All Versions

AFAIK 33-34SWG is generally used in ignition coil winding...I am familiar with auto and power transformer winding as one of my friend has stabliser manufacturing business...my pulsar always had starting problem using kick lever even i had to press self longer to start it...after some research i came to know that low ignition coil voltage can also cause this prob.....so want to increase some turns in it....IMO pulsar's coil is the worst wounded among all brands....thanks for your concern, I have one spare coil...it will be helpful if i get information regarding no. of turns...also it will help me if you could measure voltage of lighting, charging and ignition coil at these RPMs 2000, 4000 and 5000 (before RR or CDI)
Thanks

Re: Pulsar 150 garage

air pipe or drain pipe ?
dear you need to clean the carb. (esp. float and its jet)....also clean whole fuel supply line....you need to dump all fuel from the fuel tank and clean the pet cock....this problem usually happens when one rides his bike to last drop of fuel without refueling....the settled dust, rust and impurities in the fuel tank passes to the carb. causing improper/incomplete seating of the float hence fuel leakage....
temporary cure is to tie couple of tight knots on the draining pipe....

Pulsar 150 garage

Hi this is Suman. I own a pulsar 150 ebony black edition since 6 months. It was all fine till date and since 1 week it has started to leak petrol from the air pipe. When I gave to bajaj asc they checked it and told its due to petrol problem due to which float is not able to work properly and leaking petrol. It doesn't leak petrol when the bike is on or running but when kept off with petrol knob in on or reserve with bike on side stand. I need ur help guys

Re: Bajaj Pulsar 150 All Versions


The ignition coil winding generates a whooping 190-200+ volts of AC when revved, though with low amperage.. I have checked with DMM..!!! this means the guage of that coil is very very thin and we cant wind as accurate as the company did... Also the outcome may not match with the original coil and also life of CDI will be a question...!! The CDI of pulsar (AFAIK) is very very sensitive to voltage fluctuations as well as weather conditions(wet)..!!!

It will be better that you purchase new stator coil..!!!

Re: Bajaj Pulsar 150 All Versions

nice to hear you traced the leakage......get the tappets. front brake and chain slackness for the poor economy issue.....enjoy your ride....

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

couple of days later started severe starting problem and gas leakage from drain pipe ....cleaned the carb and its clogged float needle and valve...starting problem continued....plug giving spark......opened the stator plate to check the coils' resistance....all readings were perfect except that of ignition....it showed 25 Ohm whereas service manual specifies as 200 Ohm +/- 20.....So the ignition coil has shorten providing weak spark and stator plate heating.....
Can anybody tell me the wire gauge and number of turns of ignition coil? thinking of winding the ignition coil.....

Re: Bajaj Pulsar 150 All Versions

Glad you found it! The mending of broken box can be taken care. Could be fun. But look out for replacement if it is way too damaged.
Replace filter and hoses too if necessary. It becomes hard over time.

Re: Bajaj Pulsar 150 All Versions

Bingo! I found it, my AF box is broken and there is gap between it's cover and also AF is not properly inserted. Even the air is linking from AF box to Carb. Whenever I start in morning, I hear sound which is like cracker bursts whenever I kick bit hard. So this Sunday, once again I am going to be busy

Re: Bajaj Pulsar 150 All Versions

I have owned this model. Wonderful ride ��
Brings back lot of memories.

BTW check for air leaks in and around carb hoses, exhaust bend and AF box as well.

Re: Bajaj Pulsar 150 All Versions

buddy erratic idle is generally caused by lean mixture at idle due to air leak in intake or blogged idle jet.....double check the fasteners of the clamps of intake manifold......get the tappets set....improper tappets setting causes the engine to halt during idle (cold start) as the engine warms the prob. vanishes and also low mileage.....check drive chain for over-tightening and front wheel for free rotation...

Re: Bajaj Pulsar 150 All Versions

I have cleaned the Air Filter as mentioned and also retuned the Card, but still the issue is same, even after running engine for 15-20 minutes. Also the fuel economy is around 25 KM/L. I was having doubt on engine itself, but the strange thing is that the machines powers up in just single kick in morning. Last month the engine was open when the Kick Spring got changed, at that time got a chance to see inside the engine and eveything was looking to fine. Now since the engine was mounted again, there is no oil lick, all hose pipes are replaced and secured by fasteners, so no air leak, even Card was open and Diagraph seems to be fine, all jets are clean and not clogged. Also air screw seems to bit worn out as was able to see black lines on edge of the screw.

The problem is that when the engine is running below 2K rpm, it is not stable, but when it crosses above 2K rpm, then the needle stabilized like charm.

Re: Bajaj Pulsar 150 All Versions

First clean the air filter and retune the carb....if the problem remains then its time to clean the carb......is the idle unstable when the engine cold? report after doing these...
