Hi Prabhakar,

I'm not sure why this problem started. But the only change from the normal routine was the use of fully synthetic oil in my bike. The castrol mechs say that the second bore-piston change was required because the first kit, when installed was not properly done. (Please note that the first time, the Bajaj A.S.S did not open the entire engine assembly i.e. till the crank, connecting rod and stuff. They just did the bore-kit and maybe valves, seals and all) That's what the Castrol mechs had to say. The bajaj A.S.S did not correct the play (if there was any) in the crank and hence the abnormal wear of new bore kit and hence the need for second overhaul. Does it make sense? Sounds sensible but needs an expert opinion. :-?

Also, i wanted to do proper break-in this time for my mc. Can experts guide me on how to do a perfect break-in this time. The motoman's method might work good for international motorcycles with high quality parts. Will the same method stand good in case of Bajaj parts? I'll be getting my mc this Tuesday. I want to keep it in good condition this time at least.

All experts, please let us know more on this.

Some help here please. I'll be getting my mc tomorrow.
Should i just follow the manual and keep speeds below 50kmph (5000rpm) (oh and yes i know i need to vary the speeds all the time) or is there something better i can do?

Please do keep in mind while advising that i have a Pulsar 150 UG3 model. It's a Bajaj and as many of you might know, its quality is definitely not comparable with other manufacturers.

Thanks in advance to all experts.

Dude here is some deep info about Run-in / break-in thanks to Payeng for this clear article. Engine Running In- Comprehensive Details [What, Why & How] | The Bike Chronicles of India

first of all, if you are purchasing a new bike, how come you are getting UG3??

second thing, bajaj quality is definitely comparable to all indian bikes, no doubt about that, please clear it from mind, otherwise you may not be able to enjoy your ride.

third thing, keep your speed below 50kmph for 1st 1000 kms. a proper running-in procedure is there in your user manual, read it ASAP.

Haha i think you did not read my first post.
I have an old Pulsar150 UG3 2007 model. I'm just giving the engine an overhaul. Hence the need for break in procedure once again.

Hmm i'm a bit skeptical about 'Bajaj parts having equally good quality'. The Castrol Bike zone mechs even are not so confident even when they're getting my mc overhauled. They see a lot of Pulsars coming in everyday, they say. I don't think so many pulsar owners would hop into Bike zones just for chai paani. Bajaj parts obviously has some quality/endurance/reliability issues. Its a fact.

And I love my Pulsar very much. No doubts about it. That's the reason i'm investing for an overhaul. I might as well just sell off this and buy some better one. But no, this is my first mc and i'm keeping it forever.

Thank you Prabhakar, this is a very nice link. I'll go through it carefully.

You are welcome mate mc ??

Hai everyone,

have any tried to increase the performance in p150 here...i mean ffe,changing the air filter,sprocketing???..i want to improve the torque of the vehicle dont mind even if its at the cost of topend as i will be using it only in the city...any inputs guys??

Even i am looking for the details of P150 with performance mods. Could not find out. But swapping the camshaft with P220 increases the torque of the bike as per the user who have done it here. It is a longer duration cam, keep the valves opened/closed for more time than stock cam. Correct me if i am wrong.

And yes if you do undergear, the torque increases but mind you , you wont be happy with it. I have done it and the bike is really stressed and badly needs 6th gear. My top speed after under gearing is 105 kmph (speedo indicated), it does not go beyond that. may be 2 or 3 more if i crouch on tank. So dont go for it. Today i am going to revert back to stock gearing.

good info there....how about changing the sprockets??...IIRC it will also affect the top end(dont know for sure)...any ffes available for p150(not just for sound)....have anyone removed catcon from the bike..coz there will be significant improvement in the power i feel...

Stock settings and parts are best i think for overall reliability of the bike. increasing torque by changing a high lift camshaft might do bad things to the engine. If performance is the main concern, probably higher cc/better technology bikes should help. i'm referring to CBR 250 and R15. they should give you better performance but for a greater price however.

But i think instead of spending on increasing performance of the existing P150, one can think of saving up for a higher displacement motorcycle. This is what i think. Just my humble opinion.

Dude thats what i told in previous post. I have under-geared my p150 by changing the front sprocket. The acceleration has improved significantly but sure at that cost of top speed If you want better acceleration then go for it. Change your front sprocket(15T) with discover 135 sport's sprocket(14T).

Reg CatCon i think it wont make any difference in performance apart from increase in emission levels and sound.

The reason is simple for me. I cant afford a CBR or R15 as of now. I agree on the reliability part, anything other than stock will make it less reliable

No i wont mod my bike by spending more than a lac these are simple mods dude. The gain in performance will also be very little though.

@ab47..what you are saying is right..but i dont want pimp the ride in such a way that it will affect the relibility..and the quality of mods again depends on the person who works on it..for ex:consider the works done by joel on p220s n r15s they are as reliable as stock ones...

In my case,i use p150 exclusively in city so i dont mind in loosing top end for better accelaration(torque)..in case if i need top end i have another steed in my garage..dont get offended buddy..i am getting mods done to suit my utility and without abusing the engine much



@prabhakar...good info there mate!!..will try undergearing sometime soon..

Wow i've heard a lot about Joel in this forum and about his R165. Its amazing how much of techies you guys are.

Good luck Harsha. All the very best and please keep us posted on any updates.
