I've been reading this thread from the beginning. Frankly, it's disheartening to see so much negativity from the experienced modders whenever someone wants to mod their Pulsar. The immediate response is 'Don't do it, it doesn't work'. And then, on more prodding, the replies become, 'Yeah, we did it, the bike has awesome low end, runs at 120 all day on a 40T rear sprocket, but the clutch doesn't last'. Well of course the clutch won't last if you run it at 120 all day, and modify the engine to the limit. I'm no expert, but even I could have told you that.

Then there's the comment about how an R15 that costs more than 1.1 lakh on the road has better quality than something that costs 60K. Should I be surprised about that?

And the icing on the cake is that there's not a single tip about what exactly could be done to improve performance. No tips on how much to port the intake, no details on how the new intake was made, no tips on sprocketing, re-jetting, nothing.

Thanks for everyone who actually did provide useful information, like tyre selection and stuff.

@ doctorque: Yes, you probably need to upjet and tune your carb a bit. You didn't mention whether your bike is a 150 or a 180. If it's a 150, it's probably running the 107.5 size main jet. You can upgrade to a 117.5 size jet from the P180, or the 120 jet from the Karizma if you already have a 180. You can order the main jet kit (jet + holder) from most big ASCs. It will cost less than 200 bucks.

avinrichards: I know this answer is a bit late, but I believe that you will need to use the fairing mounts from the new model, or modify the existing ones. I know that it can be done.

Thanks dude.. just decided not to go ahead with . with no help from here went on a learning tour to different workshops and got a lot of so called "gyaan" and ended up keeping it stock. The discouraging factor being that i off road quite often (exploring you see) and lowering the fairing would mean the fairing touching the front mud guard. So..

@vivekGK - I have done quite a lot of work on the pulsars and we even went into building a 242cc pulsar back in 2006. At a time when the p220 was not launched and only the 180 existed.
The reason why a pulsar is not a preferred choice for mods is coz of the following reasons,
*Very weak internals, including crankshaft
*Structural engine deisgn is bad to take up mods
*Clutch, valve train and the power train snaps
*Quality of the components are bad and OE components snap when pushed just a little over stock levels
*Having a very bad design, mods do not yeild the right results
*Since the engine is not refined, harshness multiplies when radically modified
*Poor handling to take on more power and push to limits

A pulsar has never been raced around a circuit coz of the handling woes and engine reliability issues. Although FMSCI has homologated the pulsar 150/180 in 2006 not a single entrant has raced a pulsar.
We have been there and done that on a pulsar. The engine can take some mild levels of tune and not more than that.

Now coming to a few other bikes which can be modded to next levels. One of them is the humble and conservative looking Fiero. Costs lesser than a pulsar, back in the days and turns into something else when modded.
A few reasons why a Fiero/RTR is better to work on are,
*Super strong internals
*Valve train and power train can take higher rpms and abuse
*Terrific build quality of internals components
*Clean oil flow and oil pump failure has never happened on a Fiero/RTR
*Can take upto 250cc with good reliability and the OE components work well with mods
*Engine refinement does not take much beating and the engine responds well to good tuning

If you dont know what I have done, well I have built some 100 iterations of the Fiero since 2005 and my Fiero 200 was pumping over 22 horses back in 2007 and clocking 144kph in 700mtrs on the speedgun/sigma. With reliability that ensures the bike takes all my abuse everyday. Would do my office, home and track commute all on the same machine. I have build all possible combinations of the Fiero from 155cc to 200cc i.e - 155, 160,165,172,175,180,185,194 etc. We have even built a 250cc v-twin Fiero. All these numbers are in cubic capacity.

Coming to the R15..well the r15 has nothing much to make it cost 1.1L. Its the heavy import duty on the engine which makes the bike expensive. Else it would just about cost us some 80k. That engine again has strong internals (still not on par with the Fiero/RTR) and the engine can take some serious power and abuse. Something more surprising about the R15 is the fact that the engine is very compact and yet manages to give all that grunt.
Again, FYI I've built the fastest Street R15.

So, why would someone invest time and money on a pulsar when its been proven of its capabilities.
Once bitten, twice shy!
if you have a pulsar, just keep it. All of us got our rides after paying some hard earned money. if you are serious about modding, leave a pulsar alone.
Why would people world over work on a Honda engine and not a Hyundai?
Every engine has what is called as a "mod compatibility" and world over Japanese engines score the highest. A Fiero/RTR is basically a japanese Suzuki product and so is the R15 a jap. So is the Karizma(another super engine), old CBZ a good example of Indian made jap engines. Performance in stock can be whatever, but when the engines are pushed things will take the reverse order. The Bajaj R&D has serious shed some blood and sweat to make that p220 reliable and fairly powerful.
So a pulsar has a long way to catch up with the japs. Hope Bajaj makes an all new engine for the pulsar, it badly needs one.

Firstly, thanks for the reply. I appreciate it.

I remember hearing about the 242cc Pulsar on the old Xbhp. I was around then under a different ID which I've since lost the password for.

I agree that the Pulsar is not the bike for heavy mods. However, it would be useful to know what can be done to get a bit of extra oomph out of it for regular street use.
I agree. Pulsars are not track bikes. The classic 180 was awesome back in the day, with the short KB100 wheelbase, steering damper and the scary-brilliant handling aided by the rear 100/90. But then on, Bajaj has focussed more on stability than flick-ability, IMO.

Exactly. You guys know what you're talking about. So what exactly is the safe limit for a Pulsar? And I have really no idea what you mean by mild levels of tune. But I suspect that what you would call mild would be way more than what the typical xbhpian would hope to achieve. I don't doubt your credentials. I've seen your work featured in mags and on Youtube. Both the v-twin and the 3.5 sec R15.

Well, in my case, my bike is 4.5 years and 20000 kms old. Of that, 10K was covered in the last two years. It has low resale value, and I don't see the point in selling it off for a low price, so I can get another model and invest more in modding it. Besides, Pulsar parts are comparatively cheap. So even if something goes wrong and I fry the engine, it won't cost me the world to fix it.

Oh, absolutely. They need to start over from ground up, both in engine and in styling. After all, what use is having one of India's biggest R&D labs if all you're doing is well, modding?

I don't think it's possible. I asked my mech if it could be done, he said that the kit was not a direct fit. Mounting points or something are different. Mine's a UG2 though. Might be possible in a UG4 or UG3 with the short-skirt piston and the different pin. Check before you buy the parts. What you could do is bore your cylinder and fit an oversize piston. I've done it.

Hey guys,
I want to modify my Pulsar 135 LS but have some querries as listed :
1* I saw red LEDs in Air filter scoops,below the engine.alloys of warlock's Red pulsars in Stunt Mania underground. If i get some thing like dat will the wiring not affect while moving at high speeds/ in rains.

2* Where can i get extra mods of Rouser 135 in Delhi.

3* If i remove the rear mud guard and connected rods and saree guard, will it not interfere with suspension of bike.

4*I want to change the rear mud guard to semi mud guard as in Rouser 135(can see the pic).Where can i get that in Delhi and any idea how much will it cost.

5*Which wax or polish should i use for Red pulsar.Any name or brand and cost?

6*Some people use some kind of paints or sprays for blackening of tyres.What is that thing called?

7*which engine oil is best for P135?

Please help as i'm a new biker and doesn't know much about it.
Please also refer to rates where ever possible.
Thanks in Advance.
