sometimes some strange things happen in pulsars, you may find a lot of pulsar owners running at 4.5 turns also. and just for record, mine runs at 6.5 turns. so keep on increasing till you find the heat to go down a bit.

above message has a warning sign attached to it: this is based on personal experience and collective experience of other P150 riders. take it or leave it. there are happy P150 riders at 2.5 turns too and there are others like me who are at 6.5 turns.

earlier my pulsar also used to run at company settings untill all of a sudden it started to heat too much with a burning smell. i tried everything but in the end had to increase this setting to get it right. similar things have happened with other riders too.

just one suggestion- while doing all this, keep an eye for fuel consumption.

Hi there,

Thanks for your help, prabhakar and rpmboy my problem is fixed .. i did exactly as you said I rode my bike for sometime and then found out the idling screw and turned it, Now my idling rpm is 1500 and my bike does not stop anymore when i let go my throttle...

But I ****ed my bikes engine real badly, my bike is nine months old and I take my bike to office everyday, I ride about 60kms daily... I changed the engine oil first at 1500kms reading.... the next oil change I did was at 5000kms .... I usally rode my bike at 110kms to office since i ride on the Chennai bypass road which is highway...and once day when i rode above 110kms/hr my engine was like out of breath and started to slow down suddenly.. i pulled over gave it a rest and started again and it started, but the engine sound was completely different it became more rough.... then I took it to my mechanic who told me I have busted my piston rings or the pistons themselves and the engine oil will get evaporated very quick...

now wat happens is I have to change engine oil every 500kms since it get depleted very quick... the reason is the piston collides or has contact with the bore and results in lot of friction which causes heat and the heat burns up my engine oil..... my mechanic suggested the only solution to this is to change the piston and bore ....and it would cost me around 8k for that seems...

Guys should i take it to bajaj service center to fix the engine...? or should i leave it to my mechanic.. my mechanic is experienced with pulsars and apaches... im confused now ... I dont know wat to do.. my pulsar is out of warranty too since i did not use the free service..im ****ed

To take the bike to an max out , there is a revved way to do that...where u need to understand the limits also . The indicative speed of 110kmph is hard on latest Pulsar150 as the machine is made more for mid end performance , but still you should not go to that speed every now a then . Stay away from that top speed as long as you can .

Also find any kind of smoke coming out from the silencer which means the engine oil is getting mixed in combustion chamber . But as you said an 9 month old machine thats comes to 13000+ kms approx , (60kms * 24days * 9months) , quite early for head-kit to change but yes a lot depends on riding conditions on the bike engine .

So , if you can detect white-smoke which is stable coming out with respect to rpm of engine for example as revs are increased the smoke will also increase like mosquito killing device bu Municipal Corp . , ask the mechanic to open head , see for wear & tear on piston head ,

If no scratches , on head , I think only a rings be changed until next problem arrives for full conversion i.e Piston-kit set . What ever you do keep patience to complete minimum run-in kms for your benefit of your bike's engine .

thanks for the reply rpmboy, i put on my bike on neutral and revved it to 7k and found black smoke coming out of the silencer .... wat do you think might have happened ?.....wat do you suggest me to do bro..???

Thanks in advance for your reply...

Small update on my problem..

I changed the bikes engine oil to castrol 4T semi-synthetic engine oil... I have been making some long rides and I made sure not to exceed 7k rpm.... now the past 1 week the engine oil level is constant its not getting depleted..

I know that there is something wrong with my pistons and I have to change them one day.. but as of now as long as i dont cross 7k rpm my engine oil level stays good..

the bike shoots black smoke in high rpm and low pick up.. the bike dose'nt pull.. if i have a pillion behind me, the the acceleration becomes really less. but fuel economy in ok. i'm getting 45-48km/l. when i accelerate it makes a wierd sound, as if i have installed k&n airfilter, but i have'nt. the sound is not prominent, but i can hear it with my helmet on.

can i change my all down gear pattern to 1 down 4 up in pulsar 150 dtsi 2004. The 1st dtsi model.

but all the mechanics say the engine is ok.. i have refered this prom in other site also n some people asked me to get a new carburetor. so can u lemme know the aprox price of a new carburetor. n ok i wont change the gear pattern.

Mileage update:

I have a 2004 P150 Dtsi which has done 58945kms till today. i just checked my bike mileage today. from reserve position i fill 200rs petrol which comes to 2.8 lts in Mumbai.
Today when it came back to reserve i had completed 150kms in 2.8lts which comes to 53.5 kmpl. I am very happy with the performance as i never thought i would get this mileage, was expecting 45-48 as my bike it old and i have done engine mods also.
Like KnN filter with jet modification and also done Head porting to adjust with more flow from the filter as i was not getting perfect setting with Jet.

If Black smoke is coming that means Carb is not set . The sign of warning will be white smokes while revving hard . No wonder , I hate Castrol for some really good reasons , I think Motul in 15W40 or Servo in 20W40 is just fine for our Pulsars .

Tell me one thing , have the CV Carb opened any time in past ?

thats great.. Congrats.. Evn i hv got a pulsar 150dtsi 2004.. Mine shows 45 47 and 1nce it showd 58. Bdw i got it 2nd hand few mnths bak...
