Re: Pulsar 150 stalling issue while accelerating

Does anyone here feel that the first and second gear are really short geared and that the 2nd should have been the first gear? It pulls okay'ish in the first gear but post 3K RPM, it really starts giving vibrations and temper. 2nd gear is okay with the pull but near the same range of 3-4K RPM, it again shows roughness, vibrations and lacks that punch. There is no way to get the maximum possible burst of acceleration without having experiencing the vibrations. In 3rd, 4th and 5th gear, the bike pulls neat and clean without any fuss or drama.

Can this be altered? I feel there is not enough power generated in that 150cc engine and that the torque is a bit low considering the weight it carries which often gets me thinking of getting Duke or CBR. :'(

[MENTION=54284]Manan[/MENTION] : I guess you can get that round healights fitted to the current gen bike but not sure about converting the digital meter to analog. You still get that 15L tank, infact it drinks more than that, somewhere around 18L of petrol to the brim. I find the current digital speedo to be more easy to read and amazingly clean and neat design. It displays the required info quite easily and that is what I like about it.

Re: Pulsar 150 stalling issue while accelerating

I own a ug 2 model & recently did a continuous ride of 75 kms at a speed of 60 - 70 kmph. When I took a break, I found the engine to be extremely hot & light fumes were also emerging.
I have done so many long rides on the same bike but never experienced so much overheating!
I have recently changed the oil to motul 3100 20w50. The oil is still clear & transparent & its only 200 km old.
I checked the spark plug. Recently the AFR setting has been tuned & I thought may be the tuning is not perfect. But color of spark plug is light tan which seemed ok.
Also, during the ride after the break, the bike felt very sluggish as if somebody has tied a rope from behind & pulling it behind.
Earlier by bike felt so smooth & effortless & now its the opposite. Completely sad... I didn't speed over 60 kmph. I was riding with a pillion. The bike is 31000 km old & maintained perfectly.
What can be the problem?

Re: Pulsar 150 stalling issue while accelerating

Hi akash,, even i used to feel the same way until some time back.. the thing is, the gear ratios that these companies give are after a lot of research and keeping in mind their entire customer base in the country.. while the 2nd gear in place of first is quite tall, i do feel that a ratio between the 1st and 2nd can be used for first gear.. but that would be true only for us people living in cities in plane regions.. I used to feel the same about cars too.. but my mind changed after i recently went on road trip to lonavala and a small road trip to a small hill near our city where theres a temple.. and guess what.. there were climb sections in the road where i was forced to keep the bike and car on 1st gear only.. on 1st gear the vehicles would climb easily and the rpms would go high but as soon as i put them in 2nd gear, no matter what, the rpms started coming down slowly and then again i had to shift down... this was a continuous process.. shift up from 1st to 2nd, and then back again.. and then i realized.. that these gear ratios are given keeping in mind an all round usage of the vehicle.. there are people in cities and also hilly areas .. and people living in cities going to these hill stations.. at that time, this first gear wouldnt feel so short.. vehicles we drive are for an all round usage and not like racing cars which are optimized before each race for the track they are supposed to race on...

Re: Pulsar 150 stalling issue while accelerating

I agree to that fact mate. Its just that the vibes tend to irritate couple of times. Plus the crazy harsh gearbox isn't helping either. I again say, its a fantastic bike for city use and even though 1st seems to be short, it does help at some places. We don't have a lot of mountains out here with heavy two wheeler use

Re: Pulsar 150 stalling issue while accelerating

Hi guys,

I have my old pulsar 150 classic round headlights.. recently painted it at home, had the tank chromed and some other maintenance stuff.. but its just sitting around .. take it out for an occasional ride because it's really close to me .. am not gonna sell it..

now i was wondering about small tweaks here and there for slight performance gains..

know all the basics about air intake, free flow air filter and exhausts and jetting the carb etc etc.. i am interested in doing something more close to the engine and found out some stuff about advancing the cam timings or the valve timings.. many have claimed quite significant increase in the lower and midrange torque and power which is what i mostly use as I dont plan to take out this bike on long fast rides out of the city..

has anyone experimented this on their bikes.. if so, would like some first hand info about the differences observed after the changes . and differences in each aspect . not just power, the engine note, acceleration, fuel efficiency drop or rise while easy riding etc etc..

I need some guidance regarding this. sorry if this topic has been discussed before but this thread is too long to read all the way from the beginning and the search doesnt return any desirable results..

thanks..

Re: Pulsar 150 stalling issue while accelerating

sold my beloved P150 DTS-i ... it served me well since Dec 2006...lets see how the bigger brother P200NS fares in the long run.

Re: Pulsar 150 stalling issue while accelerating

This could of course be an experiment mate unless you remap the chip in CDI unit. AFAIK, you cannot advance the timing. It is controlled by the CDI unit that is under the seat. The CDI unit has 2 maps within - low end and high end. A reed switch on the carb sends signals to the CDI unit that in turn activates the corresponding map. This is just my opinion though. All the best!

Re: Pulsar 150 stalling issue while accelerating


I was about to say similar thing, to get the CDI unit swapped with bigger Pulsar bros. One of my friend's had suggested me to swap my P150 UG 4.5's CDI with that of the original P200 and that it is said they have the same layout and design. This will effect the fuel efficiency but since I am two minds of selling and keeping, I am not able to get the swap done. It will be an experiment and I want to keep the bike as close to stock as possible, so it all depends on your choice mate.

Re: Pulsar 150 stalling issue while accelerating

The power delivery of the bike lies not in the CDI unit but relies on various components. Primarily the bore/ piston stroke and compression ratio delivers power. The CDI just times the ignition to facilitate combustion.

+1 on that.

A 150cc can deliver only 150cc. Anything beyond that we are going against the bike characteristics and loosing the real pleasure it has to offer. Unless I have a big pocket I ain't going to experiment . Hope [MENTION=51207]puneetritehere[/MENTION] keeps us posted!

Re: Pulsar 150 stalling issue while accelerating

guys . i think you've me confused.. AFAIK the CDI unit that you guys are talking about controls the ignition timing or the spark timing and has nothing to do with the valve or cam timing.. cam timing is something that is controlled fully mechanically and has nothing to do with electronics. the opening and closing of valves will be controlled by the position of the cams relative to the position of the crankshaft.

what i am talking about is setting the camshaft in relation to the crankshaft such that the valves open and close a little before than they usually do. this is advanced cam timing. you guys are talking about advanced ignition timing. ie. how much in advance the spark plug delivers a spark so that by the time the piston reaches TDC the fuel is already burning and delivers maximum cranking power.

Re: Pulsar 150 stalling issue while accelerating

You are right and honestly I haven't come across anybody who have experimented this.
If my understanding is right, you are looking at a lengthened intake valve timing to allow more air fuel mixture for enhanced combustion and power?
The dynamics of engine change by advancing or retarding the intake camshaft relative to crankshaft/piston position and relative to the exhaust camshaft. I guess this requires extensive research and knowledgeable mechanic. Have you known anybody with such a modification for quite sometime? Check them out first!!!

Re: Pulsar 150 stalling issue while accelerating

Hi,
I just bought a new Pulsar 150 2 months before and covered 4000KM since then. Now I want to install HID for my trip to Musoorie. I'll be riding at night that's why I think HID would be a better deal to cop up with dark night on mountains. Please advice me some good HID which I can install on my bike.

Re: Pulsar 150 stalling issue while accelerating

HID installation might require alterations to the stock wiring and adding relays. The battery would not retain the charge with continuous usage. Many have experienced the same. Since it is a new bike, you need to consider the warranty as well. Know that some have installed HID by changing the coil of Avenger's.

Two options for ya-

1. the best solution would be to install fog lamps with a separate switch
2. change the stock bulb to Osram/Phillips

Drive safe!

Re: Pulsar 150 stalling issue while accelerating

Thanks for the suggestion
Can you please tell me which fog lights would be better? And how much will it cost for Osram/Phillips bulb? I want white light like the one in HID at 5000K. What will be the total cost including fog lights and bulb?

Re: Pulsar 150 stalling issue while accelerating

There is no OEM fog lamp for bikes. You get only aftermarket ones. They are reasonable and you can't keep using them all the time - only when bike's engine is running.Fog lamp - 350/-Osram/Phillps (check if it is available for P150) - 1200/-Aftermarket white bulb direct fit - 200/-
